400w aircooled digi - Dynamite + NL?

G

Guest

I recently got my medical card in Oregon for Degenerative Disk Disease (I've had pain and muscle spasm cycles for ten years or more). My wife and I have been thinking about growing for some time but until we moved to Oregon earlier this summer it wasn't really an option without a medical program.

We live in an apartment and we decided to convert a deep closet (42" deep, 27" wide, 65" to the shelf that forms the top of the cabinet, 9 foot ceiling above) into a grow room. We talked at one point about buying a BloomBox, but decided we could acheive the same thing for much less money ourselves in the closet space. Four hundred watts seemed like a nice neat number - I knew it would definitely produce plenty of bud if other conditions were good,
and anything larger seemed problematic for such a small space.

One of the local grow shops had digi ballasts in stock. I got a 400w Future Brite. It runs quiet and very cool. It turns out that the Sun Tube has built-in socket and wiring assembly, which is GREAT if you have a regular coil ballast, because you don't have to deal with any socket issues and you can just plug it in and in the wiring is beefy as hell. But it SUCKS if you have a digi ballast, because they have a plug pattern that's different from standard ballasts, which means you have to re-wire the reflector. Yes, I'll say that again, if you get a Sun Tube, be prepared to rewire it to work with a digital ballast (you have to cut the male end off the cord build into the reflector, and splice on a male end from the socket that comes with your ballast). In the photo of the space above the cabinet you can see the electrical tape on the wire to the lamp - that's where I worked my magic. It was a little bit fucked up, honestly, and I felt like the grow shop should have given me some heads up instead of leaving me to figure it out for myself and then being like, "Oh, it's a simple wiring issue". I still wasn't sure when I was first setting all the shit up if all of the stuff was going to end up working in that space or not, so cutting the wiring on the $200 reflector was something of a gamble. But I'm stubborn and generally don't hesitate to go hardcore in such a situation, and so the gamble seems to have paid off.

The hood is cooled with a 180cfm CanFan inline blower. I bought the smallest Can Filter I could get which is still way more than I need, but overkill in that department is probably good. For main ventilation I ran about two inches of ducting from the carbon filter to a 30cfm Radio Shack fan in the wall of the cab. The space is 40 cubic feet, so 30cfm yeilds an air exchage every 1.33 minutes, which is pretty good. The temperatures stay 80-82 with the light on, now that the weather is cooling down here. For a few days recently it didn't get below 80 degrees ambient in the apartment (it felt fine because it's not humid here, but it meant the chamber couldn't get below 85 with the light on). That's maybe a little bit high, but I'm planning to add CO2 soon, so that will raise the temperature ceiling by a degree or two.

Air is drawn from the space above the top of the grow chamber inside the closet, and expelled out the door. Cool air comes in the lower part of the chamber (I'm going to add an intake fan at the bottom soon, but it's currently just passive intake) and is pulled through the filter and exhausted at the top.


Top of the cabinet (intake for the reflector hood) and ballast.



Underside of the light. It just fits in the closet.



The closet is to the left of the open door. The light on the right is the T5 CFL, which is only there because we don't have anywhere else to put it since my slow ass hasn't built the veg box yet.



I don't have any indoor grow experience so I wasn't exactly sure how best to approach the ventilation issue. I decided to go with an air-cooled hood. The best thing around here in the shops seemed to be the Sun System Sun Tube. I purchased a 2' T5 CFL made by Sun System and and have been really happy with it, so I decided to go with their stuff again. The Sun Tube is a 6" tube, and as it turns out it's the perfect size for our space. The wing reflectors make it the needed width, and it fits perfectly lengthwise with the ducting in place.

Right now the light is just hung on chains from the rod in the closet. Fortunately, the rod is about an inch off-center, which means I can install a light yo-yo in the center to hang the light and not have to remove the rod. With the light at the top of the cabinet, it's a little under 6 feet off the floor. Even though the height is somewhat limited, the air-cooled hood should allow the light to be closer to the plants than it otherwise could be. The fact that it's a 400 as well should let me use most of the vertical space up to the light without burning the plants. Hopefully I'll be able to work with some sativas and not just have to grow short indica stuff.

Once I got my medical card I started buying the equipment and putting things together, and then about a week later some plants fell into my lap. I met another patient that is growing Dynamite, which won the Oregon Medical Cannabis awards here last year. It's a mostly sativa plant - tall and spindly, thin long leaves, lighter in color. It grows almost like a vine, meaning it's great for SCROG. The patient I got the plants from grows them in a very short (40 vertical inches or so) cabinet with a 400-watt light and trains them on a trellis. He keeps them short and contained and still gets plenty of bud.

As a side note the Dynamite really is aptly named. Dried bud is so sweet it just reeks - the smell is almost fuelly. It has a nice clean motivational high that lasts a while, and still has a relaxing body component as well so it's a good medicinal choice. The plant produces long straight swollen trichomes that cover even much of the leaves. I'm sure it would make excellent hash, although this particular grower hasn't tried making hash out of it.

He gave me three plants that are about a foot tall. They're all somewhat rootbound, and when I got them they were yellow and droopy as you can see in the first picture. In the few days they've been under MH light they've started to perk up and grow. I have improvised some training ties in lieu of fashioning the proper screen for SCROGing. The plants were in small (maybe 3") square pots, and I transplanted them into 5-gallon growbags that are about 2/3 full (so around 3 gallons of soil). Here's a pic the day I got them. They were under HPS light for a couple of days because I hadn't had a chance to get a MH bulb.



Our cabinet is the perfect size for three 1X2 flats with a little room to spare all around. Two plants in 5 gallon bags fit nicely into one of those flats, so that means the closet is well-suited to hold six flowering plants, which is our legal limit. Most of the time it will be exclusively a flowering chamber - I'm planning to build a separate veg box with CFL lights and its own carbon filter.
Rather than build a single screen for the whole closet, I'd like to have each flat have its own screen, so only two plants are fixed to the same screen. This way plants can be taken out two at a time, and also means that multiple strains can be grown.

Which brings me to the other part of the story: some very beautiful and interesting seedlings (plants now) that are unidentified. The week we found out we could start growing we got a bag of bud from someone that normally doesn't ever get seeded bud. It was limey green (a color I have only seen a couple of times) bud that tasted excellent and had a nice balanced high that tended towards the stone. Even though some of the buds were more than lightly seeded, they were still covered in crystals. The buds didn't look like anything I could remember in my direct experience, so I went online and also checked out the Cannabible to see if I could find something that looked similar. The only thing I could find with a color anywhere close to what we had was Northern Lights, but I still wasn't exactly sure.

We also had a few seeds from some good Humboldt bud we had smoked not too long before. It was some airy sativa bood, clearly one of the excellent old-school sativa varities bred for that specific growing climate.

There were about 25 seeds total. We put them between paper towels to germinate and only 2 failed to germ. They were planted in Ocean Forest potting soil in solo cups. Once they sprouted they were placed under an 8000 lumen T5 floro light. They all grew vigorously.

Strain X, the unidentified (non-Humboldt seeds) are now showing strong indica characteristics. They are dark green, and have BROAD leaves and short internode spacing. They seem almost totally indica, so the possibilities are narrowed to something like Afghani, Kush, Northern Lights, Hash Plant, and a few others. It wasn't like any of the Afghani I've smoked in terms of appearance. It looked closer to Kush than almost anything else I can think of, but the distinctive Kush taste wasn't very apparent. It had a totally different calyx structure than Hash Plant, so I think I'm ruling that out. I smoked Northern Lights a couple of times in NYC from one of the delivery services and I remember it being somewhat different, but that was a while ago so it doesn't mean much. It's probably too soon to be able to tell what they are but if anyone has any ideas let me know.





The local shop has SubCulture from General Hydro, so I bought it on a whim. Actually, the idea of using benficial micro-organisms and fungi was not a whim, but I had planned to order some Advanced Nutrients stuff and decided to use something else that was more available for the time being. SubCulture (like Tarantula from Advanced Nutrients) is a powdered mix of micro-organisms that colonize the root area and stimulate root development and nutrient uptake.

The seedlings were all planted between September 13 and Sept. 15, so they are around day 27. They were in the solo cups until about three days ago, and for several days the growth visibly slowed down. They weren't root bound but were getting close to the limits of the volume they had. We transplanted the best-looking twelve into larger pots (all of them were strain X). Since doing that, three of the Humbolt plants have shown female preflowers. Well fuck. We're trying to decide if we should transplant those also (we don't really have room, and they seem stretchy and delicate and not well suited to our purposes) or not. I think out of 12 of the X plants, I should get at least a few females, so I'm willing to take the chance just using them. I don't think the Humbolt plants would really work in our garden.

Even though the females I got from this other guy were a foot tall, they were spindly and starting to yellow. They had also been overpruned, so they only have a couple of top branches which will need to be trained sideways to maximize budsites. So given the few days it took for them to recover from being rootbound, and the time they need to develop more rootmass and vegetation, I think they're roughly on the same schedule as the X plants even though the X plants are much younger. I'm think that roughly another two weeks of vegetation are in order. That should give the Dynamite plants time to branch more, and at the rate the X plants are growing they will be too big if I let them go any longer than that. I'm planning on keeping pruning to a minumum with the X plants, since they're short and compact anyway. I'm waiting to see preflowers. None have shown up yet, but if they show sex before flowering I'll know which ones to transplant and that will save some trouble. Once they are sexed I will probably take a couple of cuttings from each in order to preserve anything choice we might get.

I'm very excited about Strain X. The seeds came from high quality smoke (much better bud than usually contains seeds), and they sprouted and are growing quickly. They're pretty uniform. As you can see in the pictures, there is a little bit of variation between them - some are a little taller and the leaves a little narrower. They are growing into strong plants. Since they are mostly indica, they are suited to our growing needs. Out of the plants we have we should be able to find at least one or two oustanding specimens.



Right now we are mostly just waiting to see what the plants tell us. Hopefully the X plants will show preflowers soon and can then be transplanted again before flowering. The Dynamite plants are perking up and with a little bit of training will be fine plants. I won't get a huge amount of bud off of them but it will be good. The Xs are drinking water pretty fast. I think in the next couple of days I'm going to start giving all of the plants a small amount of Fox Farm Grow Big.

Here's a pic of all of them (12 X, 3 Dynamite) a couple of days ago.


I will keep taking pics and updating. It won't be long at all before these plants are all ready to flower. Yay!

Best of all, this grow is legal. Give praises to the people in the medical cannabis community because they are doing hard but important work.

Looks like you have thought everything out, the room is looking good! Good plan on cooling the light i have something similar its great to get your plants close, also helps if you end up a bit overgrown like me at the mo.
I look forward to seeing strain x and what they can do in flower!
Goodluck with your grow! Must be nice being legal :)

i went to the store today and bought a bottle of Grow Big by Fox Farms. I got home, mixed it up and watered the plants with it. Then later when I was checking out the bottle I realized it's not organic. Fuck. For some reason I assumed all the Fox Farms stuff was organic. Well, I guess it's back to the store for some Earth Juice or something else similar.

I have been watering all of them for several days with half-strength (1/2tsp per gallon) SubCulture.

The light yo-yo I bought doesn't work properly so the light is still fixed in place. It's about 30" from the tops of the plants. I think I can get it closer without any problem but they are hanging at the end of their chain and the yo-yo I bought doesn't have enough tension to support the light when you place it. I'm fairly certain that my light/hood setup doesn't weigh more than the 25 pound limit for the hanger, so my verdict is that this yo-yo is a piece of crap.

Here are some pics. The X have grown visibly since yesterday - they are responding well to transplanting. And the Dynamite plants are continuing to fill out - all three have horizontal branches with what will be budsites all along the length. I included one shot that was accidentally taken at long exposure so it's washed out but the effect is cool. I was trying to take a close shot of the intertwined branches from the Dynamite plants.

the current smoke is blueberry x haze. it's well grown and cured - smells like blueberries. Has a high that starts off very up and then a relaxing body buzz slowly creeps on over like an hour. Oregon has great herb. This was $20/gram (ouch!) which is unusual but this is connoisseur weed for sure.

In the last few weeks there's been some bubonic plague (white with crystals and tropically fruity), orange crush (mild but tasty and a balanced high) and some other very nice bud that I didn't know what it was. I'm looking forward to being free of the stress of worrying about where the next bag will come from and how much money I spend on herb. But as much good bud as there is around here I'm sure even when I'm self-sufficient I'll probably have to spring for an eigth of something special occasionally.

neil: yeah, the medical thing is great. the cops can still fuck with you and people still get in trouble but it takes a big load off my mind. Plus around here since there is an active medical program in Oregon it's easy to get put in touch with growers and caregivers. So even though there aren't dispensaries (yet) it's not too hard to get some cuttings or plants when you get started. I'm hoping to get hold of some old school pacific northwest strains (Northern Lights, Hash Plant, stuff along those lines) and it shouldn't be too long since there are regular member meetings.

core:no, this is my first grow. i've been researching all aspects of cannabis genetics and cultivation for about two years though so i'm not totally starting from zero.

Thanks dre and core for the comments and for checking in. Peace everyone...

I never heard of dynamite getting covered in trichs.
I have been growing dynamite for a few years. Does it finish up purple or green?

:yoinks: then you are doing a great job IMHO..whats you soils ph
two years you say..that long my friend...i started only with the knowledge of tastes of weed ....lol
after 15 years of smoke i build me a room bought some white widow seeds and NLx clones and i jump from that cliff....now i harvested the NLx last week ...
nway maybe i shouldda done the same thing :chin:
gonne :lurk: a bit if ya dont mind... :joint:
good luck mate

rule: the plants are pretty dark green. Thin leaves, long-spaced internodes, sativa for sure. I wouldn't say these have any purple in them. The bud cures to a lighter, limey green. It might be a 'local' dynamite, something someone around here bred. I know Next Generation seeds has a "Dynamite" but it's described as heavily indica so it's not that. Perhaps it's not even Dynamite at all - whatever it is, it definitely won the Oregon Med Cannabis awards last year. It's some amazing herb. What's your Dynamite like?

Core: haven't gotten a ph test kit yet. that will be in the next couple of days. they seem to be fine with tap water so it must be within a reasonable range. good luck to you too mate!

i took the fairly radical step of downgrading the Dynamite plants from 5-gallon to 3-gallon bags. I had just realized that they would never grow into all that soil, and they won't yield enough to really be worth taking up that much space in the closet. Now all three plants can be trained into one screen.

Got some Earth Juice Grow.

Pics soon...

OK, so it turns out I'm not growing Dynamite. I'm 99% sure now that the plants I got from another grower are White Widow. They look like all the White Widow pics I could find. Widow won the Oregon Awards in 2004 so that was the confusion

Took bad I can't change the name of the thread...

Well, that's a fairly pleasant surprise. It doesn't really matter because whatever it is, it's good bud. One clue with these plants though is that the trichomes cover even the leaves, so it definitely looks frosty.

I have DDD as well my friend, I was diagnosed with it when I was 23, I am mid 30's now, holding out well, been a while since I was incapacitated. My last Dr's visit, I was told I would need to get some implants(titanium discs) but they will not do it till I get to be an older man, and I would most likely have to travel to the US to have it done. That would be alittle beyond my means I am afraid.
Anyways, will be pulling up a chair, good luck here dude.

core: amazing my friend! i realized yesterday that if my indicas turn out to be northern lights we both will have started off with the same strains =). those leaves look even a little more sativa than mine. i'm pretty sure my plants are more on the sativa side than some white widow (they're VERY viney, and the high is almost medicinal but also very up and clear). that bud formation is amazing. do you have c02 and what is your setup? i read your diary, congrats on your efforts! i never thought of white widow as a SCROG strain but these widow plants are perfect for it because they are flexible and almost formless - they'll stretch into anything you want them to

rule: amazing buds! thanks for helping me figure out what my plants were, which is definitely not dynamite... i'm sure that smoke is terrific. like i said, once i actually found some pics of widow i recognized it instantly as what I have. another feature is that the white widow i've smoked before always breaks up very easily, as though it's overdried even if it's not. it seems light but it's incredidbly resinous.

again, sorry for the lack of pics. my camera batteries died and i'm trying to get another lens anyway. the plants are looking very good with the new ferts. i'm planning on getting a c02 boost bucket in the next couple of days as well.

thanks everyone for the great energy to go into this grow. the more love the better!

peace

rule: beautiful plants!

the cured bud looks exactly like the stuff from these plants, although the plants look a little bit more indica than mine (the leaves are a bit wider). but you can definitely tell it's the same genetics. where did your plants come from (seed or clone)?

i think you can use WW for scrog quite good..if you can train them right it will be a big yielder...its quite a tall plant and mine are just in 2 gallon pots ....and my biggest 1 is 1.6m H ....they are quite sensitive IMO ...they also tend to yellow verry fast at the end of flower.
and i dont realy have a Co2 setup ....i use Bio Co2 in a 5 gallon bucket...

I was gifted a few seeds from a guy that has been breeding this plant for 5 yrs. The seeds were female and the plant is decent, not one that I am going to keep.

FLOWERING: DAY 5

FLOWERING: DAY 5

sorry for the lapse in pasting for a couple of weeks. i have been busy with other projects as well, but still watching the plants carefully.

the last time I posted the plants still had some vegging to do but much has taken place since then. at the time the tallest was around 8" i think.

i purchased a CO2 Boost bucket. this is a new product that has probably received some attention here at ICMag. it's a bucket filled with organic matter that produces CO2 as it decomposes, and it comes with an air pump. they cost $125 and the buckets last 90 days if you put the pump on a timer (so they say). replacement buckets are $100 which seems kinda pricey but it's still cheaper up front than other CO2 methods and there's basically zero setup. i personally like these a lot. $100 is probably a rip for a bucket of mushroom compost but the concept and execution is really good. with such a small space (8 sq ft.) i don't need much CO2 so even a bottle is really overkill.

i set it up with the air hose attached to the back of my circulation fan. since i have such a small space that fan blows directly onto all of the plants basically so they all get lots of what they need.

the plants were strong and healthy all along but when i added the bucket to my cabinet they blew up. with the C02 they were growing roughly 1 inch / day! it was pretty ridiculous. i vegged them for almost two more weeks after that point, then took a couple of cuttings from each plant and put them all in an oasis starter flat under a 2' shop floro. the cuttings are still rooting. (pics soon). i gave them a few days after that to recover, and put them into 12/12 under the HPS bulb (w00t for digi ballasts).

they ranged from 16-20" when flowering started and are now between 18 and 23".

here's a couple of the representative ones




they're pretty bushy.

any thoughts on what strain they are? i'm still thinking NL maybe but it's just hard to be sure.

they are now on day 5 of 12/12. i finally switched the light cycle because i couldn't let them get any bigger. them began to preflower immediately once 12 hours of light was introduced - by the second day identifiable preflowers had formed on all of them. and the results were:

8/9 female! not bad for bagseed (although the genetics are definitely high quality even though the seeds came from a bag)

so i had to take four plants out to have room left and to stay within my plant limits. these plants went to other patients along with two of the white widows, since the largest one was growing into the canopy by itself after the addition of the CO2. so now i have six plants remaining (one WW in a screen and 5 unknown but definitely indica plants)

in the last day or so they have really started the first stage of bud formation. here is the top of one of the plants (none of the indicas have been pruned at all except removing the first pair of branches as clones)




flower appearance is working its way down the plants steadily. the main flower and next two subsidiary branches are showing tufts of hairs on all the plants now.

here is a shot of the top of the longest side branch on the largest plant




the last two weeks of veg they all received half-strength earth juice grow with each watering. this is pretty frequent i guess but they never showed any signs of problems. the root mass development on these plants is really good - they grew into the 2-gallon bags in a matter of days. the combination of beneficial micro-organisms and fungi is a effective for sure. basically what you're doing is replicating a more complete outdoor soil ecosystem.

with the switch to 12/12 i modified the fertilizer regimen. they now receive a 2:1 mixture of Bloom: Grow (both Earth Juice) so 2tsp of bloom and 1 of grow with each watering. i have also continued with a maintanence application of the micro-organism and fungi mixes (once a week). I think I will continue the fertlizer mix for another week or so and then switch entirely to bloom.

i'm considering using microblast or something like that (a micronutrient blend). the plants aren't showing any deficiencies but i think at this point they have probably depleted the soil completely which means they are receiving nutrients only from added fertilizer. the soil (ocean forest) is a wide mix of stuff so i think i might need to add another element to the fertilizer to compensate. any advice in this area?

the plants are happier now that the space has been thinned out. the last few days of vegging they were dropping lots of bottom fan leaves which were shaded out because they cabinet was so full. with 6 plants instead of 12 they are much more comfy now. here's a cabinet pic:



they are very lush as you can see. i have been very happy with the growth on the indicas. i'm hoping to get an ounce or a little more off each plant (perhaps 8 ounces total). is this feasible? particularly with the addition of the CO2 i think they will be fat beasts when they finish.

temps in the chamber stay between 77-82 with the light on and 70-75 with it off (no a/c here so it's kinda variable). they've never seemed to have any problems even on the hottest days so i'm not even really thinking too much about it anymore. even when the tops grow within 4-6" inches of the light they don't seem to have a problem (this has happened a couple of times). In general i'm trying to keep the light 8-12" inches above the canopy.

remember the light intensity diminishes with the SQUARE of the distance so if you double the distance from the bulb to the plant, the plant will then receive a QUARTER as much light. so even the difference between having your light a foot from the plants and 18" is big in terms of usable light (factor of two in this case). this is a definite advantage of smaller lights (400 and 600 watt vs 1000 watt). a 400 watt light that can be placed a foot from the canopy will deliver as much light as a thousand watt light two feet away.

a smaller and more reflective chamber offsets the diminishing effect (since more of the light that doesn't initially strike the plant is reflected back). this is one of the perverse advantages of growing in a small space. another is that even a small circulating fan can keep all the air in the chamber moving so there's less of a hotspot directly under the light.

i'm thinking the flowering time on the indicas will be in the 50-day range. they seem very typically indica so it will surely be on the short side. hopefully within seven weeks or so i'll be able to harvest. the widow will probably take a little longer, probably around ten weeks.

that's it for now i guess. even though flowering just started i'm pretty excited. i should be able to post more often here in the next few weeks so i'll try not to let the thread go unupdated for so long again.

peace everyone
