scrap and kidsmoke---

i'm definitely in the same boat with the heat and my fucking portables.

i've got two blasting full bore 24/7, racking up huge electricity costs. i shoulda sprung for the minisplit from the get go but we wouldn't have had enough cash left to pay our bills in the months before the first harvey.

with the garden set up the way i have it, both flower and veg are exchanging air with the lung room/office space. i've got the portables in the lung. i have managed to get most of the dehumidification to be handled by one unit, so i'm only dumping one bucket a day, but it's a daily chore, twice on rainy days.

but they just don't cover the cooling needs during these hottest weeks of summer.

i've only been running 4 of the 6 gavitas basically since july started. at least that cuts down the electricity bill some.

i also have the three veg lights on staggered timers, so at least one is shut off during all flowering daylight hours.

with these conditions i'm maintaining 78--82* in flower with lights on. we get some bumps at the end of hot days (when it's dark outside but still 80+) and get up to ~85*, but the gavita controller starts auto dimming at 84*, full dim at 87*, and will do an emergency shut off if the temps climb to 95*

the good news is the lung is a pretty decent environment for drying, so we've been getting nice 10--14 day hang dries before trim and cure, and shit is coming out LOUD. we maintain a constant 65% rH which is right where i want it to meet the needs of veg, flower, and dry simultaneously. also the lung rarely gets above 75* so it's kinda functioning like a huge humidor.


oh! the mod! i love it so much! i built it myself lemme see if i can say all the jargon right: i've got a 32a samsung battery in a phantom mod with a doge RDA on a hybrid adaptor. my current coil i made with 22g nichrome80 and it's 0.35 ohm. i considered putting a stainless wick in there like flatslabs was recommending in the portable dabs thread, but i get such good legit dabs by buttering up the coil that i dont mind the inconvenience of packing one at at time.

i love my sssdh!

i'm actually itching to pop these 5 old rez stock SSSDH i got from the 'bay with my last order. in the f2's we made we've seen some decent variation from sour phenos to hazey, but even the fastest expressions are gonna run at least 10 weeks. she's in the same soil as everyone else and as you say, she feeds herself what she wants when she wants.

another thing to keep in mind when growing these longer flowering NLD plants is canopy management. if you're growing them alongside stout WLD 8 week plants they will not cooperate without your intervention.

you can pretty much bet on any sssdh seedling stretching like crazy when put in flower, so i'd start on the smaller side, and train or trellis them carefully to keep them manageable.

give the 12 12 from seed thread a read. seems like a great technique for growing sativa dom plants in a tent from what i have heard.

good luck!

Nice, your SSSDH reminds me a little of my ShirexSWL cut. 13 weeks and she looks like she could go longer! Yes, these ladies require tons of support, my tops are 1' above the tomato cages.

I have a nemisis mod (with magnets) with toby atty v3. I roll stainless steel with my Kanthal 24g coils and works nicely at <.5ohm. I'd love a coil jig for sure, those are sweet (beats my drill bits). Love the portable dabs thread...

I am dumping once a day now on 2 homemade portables (one for flower one for veg) that keep up nicely with the heat in Flower 75off /77on deg max at 81 for an hour when lights kick on. I like the gavita auto dimmer, I should see if my solistek do the same. My old true portables sucked and could not keep up like my upgrades can. I too will have a mini split for next summer.

Sounds like you doing well, especially in light of the wattge your running. I've been turning down ballasts on warm nights. And lately I even delayed lights on start up time until it was a more reasonable temp outdoors. The things we do to please plants, eh?

Wanted to stop by and show respect for helpin the community by documenting yo shit......and your time as well.....

First off , not trying to tell yas what ta do Heady , but portable a/c`s should always be used as auxiliary /emergency cooling if you will in deep summer , although I know you`re on a budget .....

I had good luck with 28000 btu wallbangers for the lungs and 12000 btu portables in each flip room for insurance , and they rarely kicked on except late Aug.....but.....

If your lung`s smaller than your bloom room , you`re probably gonna need to go to active intakes on speed controllers to not outrun exhaust and push smell out before routed through scrubbers.....now....

You spoke earlier about not lighting the plants but rather the room , and I`ve ALWAYS been of the mind from personal experience that if you make the room it`s own air-cooled reflector with proper watts per sq ft., and lastly covering everything that ain`t green in reflectix/prodex/orca of your choice so those lights bounce up , down , and all around those plants during lights on....

Upgrade to a minisplit and no worries bout lungrooms and such , I was always a tightwad and did shit cheap as I could without bitin me in the ass , but environment is everything......far more important than buncha light slung at em , but hey....

Keep doin what you do , and upgrade as budget permits....that`s how WE grow...:peacock:.....

Peace....DHF....:ying:......

P.S. Are those 1KW gavitas that actually dim down to 600 watts ?......awesome shit....:biggrin:.....

DHF---

thanks for stopping by my friend!

much respect to you for all the great advice i've gleaned from your posts over the years.

YES you're totally right about those worthless portables. they were the biggest compromise i had to make during the build out and they will be the first thing to go when we are able to make some upgrades.

i know it's all about environment and limiting factors, so nothing gets pushed or pumped or bumped until we have total control over temps and rH with the touch of a dial.

according to my calculations we need a full 4 tons of cooling power, which seems right about in line with your suggestions, although i had been thinking one big banger in the lung vs. the three.

would i be able to get one condenser to run all three units even tho they are different power levels?

i'm anticipating needing a bit of heat during the dark hours when we're in deep winter, so we've been looking at units that do both.

as soon as the weather cools down i'm gonna do a simple duct fan (with a filter of course!) hooked to a thermostat to bring in some cool air from outside and hopefully shut those portables down for good.

in the medium future my buddy wants to build an arduino unit to monitor and control all aspects of environment. the way he talks about it we'll be able to dial it in remotely on our phones lol. sounds good to me!

my lung feeds veg and flower rooms, and is about the square footprint of both rooms combined. it's also got the prop room open to it, although with no active ventilation and only like 100w of lights burning in there.

so far smells have not been an issue. i'm getting intense negative pressure in the flower room, almost too much--- i think if i added two more passive intakes i'd improve the flow enough to drop temps a couple degrees closer to the lung room ambient.

upgrade as the budget permits---money and TIME both--- that's the plan.

come by any time fred! :deadxmas:

:thank you:

ps---yup 1k gavita pros turned down to 600w to allow us the minimum clearance of 24". at the full 1000w we'd need over 36" from bulb to canopy. we may try doing more, smaller plants when the temps drop and turning the lights all the way up, but only after i finish fine tuning the environment of course!

Never was a better area for drying than a lungroom.......worked perfectly for me more than 20 yrs.....now....

My old wallbangers had heat pump capability for cold winters , but rarely did they come on down here in Hell.....but being in Maine presents a different X factor to be dealt with and dialed , but if you`re staying where you are the minisplit with - 40 degree backup is the way to go in the future....that way....

Yas can put it in the lung area and pump perfect environment in as well as suck out back to lung for re mix and re use....that said....

I know folks that heat their house for the winter with bloom and vegroom exhaust air using air exchange twice per minute , and have for many yrs.....It`s just how far down the rabbit hole yas wanna crawl with our lil hobby...

Ichabod Crane `s 1 that uses his exhaust for winter supplemental heating , and he`s in Mich. I `m fairly sure , so maybe he can give yas some pointers.....anyways....

Keep up da faith Bro........

Peace....DHF.....:ying:......

hehe hell yes. we're looking forward to the radiant heating in the livingroom upstairs.

the dogs and kitties have been loving the cool floors during the hot summer.

Win win as they say!

In cold weather I pull air from the unheated interior of my pole barn, though insulated ducts to my lights and dump that air in my veg room. My flower room intake then comes from the veg room. So the veg room kind of works like a lung room too.

I still need electric heaters, but can heat my rooms when the lights are on down to the mid 20's. It helps a lot compared to using heaters all the time. In the coldest part of winter, I barely keep air coming in but suppliment with tanked co2.

Using 2600 watts of light and using two electric heaters, I can keep most all my electric bills under $300, and that's for house and everything.

i'm hoping to survive mostly on the ambient temps of the house, but i think i'll need to heat a bit during dark periods to keep temps above 55. we shall see.

i don't want to open the lung to the rest of the house because of all the animal hair from the menagerie. i've got a "hair-lock" (haha yes, that just came to me) room at the bottom of the basement stairs that is not part of the garden. lung room is through another door, and there are allergen filters on the intakes to the flower room.

i'm hoping the radiant heating will be substantial. house holds heat pretty decently with those new doublepane windows with vinyl sashes. most of the heat last winter was provided by a single potbelly stove and compressed sawdust logs. i guess we'll see!

i thought i'd put up a quick insta-update while i sort through the pics from my good camera for a real update.

Heady,

I was referring to converting a window unit to a "portable"/interior one. I had true portables and they sucked. I followed the foam board DIY thread on ICMAG to build them, both with vortex fans and insulated ducting. I had 8000 portables that were awful where the homemade 6000 are more effective. My main problem is draining or dumping buckets, but that will end very soon. My house has a wood stove in basement and used it a handful of times due to radiant basement light heating, very effective and highly recommend.

In my other space, I am also planning to flip room ventilation with lighting times to heat the dark room twice every minute. In addition, I am getting a mini split next Spring (just upgraded to 400a). My calcs for two 10x20 rooms on flip was two 18000 indoor units and one 36000k outside unit. I don't expect to need very much heat, using electric heaters this winter to get by.

WOW!!! Everything looks grand Heady.l Very stoked for you friend. I recently watched a tutorial put on by the CEO of Gravita on the new lights. I think they are fantastic. I upgraded ( or thought I was..lol) last winter on one of my rooms. I replaced the 1k's with the double ended bulbs. Man are they strong..whew. I never thought I'd ever mutter the words too much light but indeed there was. They need to be mounted on minimal 8 ft ceilings. i had a single one in a 5 x 5 7" tent as well and the same thing..
A word of caution on your ducting outside air. Use a bunch of filters. There is a terrible tomato blight going around Maine and it'll kill your plants or at least cripple them to minimum yields. I got powdery mildew through my intake as well. I'm still going bring in fresh air but a friend has designed and built a box with a bunch of reg furnace filters that rectifys any bad stuff coming in. Hes got two shops in Maine. shoot me a pm if you are interested..great thread Heady..peace

good call guys.

i should consider the flip rooms for the winter. it is the most sensible efficient way to deal with nighttime environmental issues. plus free humidity for the daytime side!

i'm still not 100% on the outside air, but good filtration is a high priority for sure if we go that route. honestly i'd like to just buy the minisplit now for peace of mind. gotta keep grinding for those upgrades!

it would be nice to get a break in this heat so i could run all my fucking lights for once! at least i'll have a bump in yield to look forward to when we have all bulbs blazing.

i've had lots going on the last couple weeks. thrips are fully under control. then those uninvited august visitors were spotted munching on the beyond the brains: two spotted mites. i don't freak about those, but i don't ignore them either.

we took those gals down immediately upon identification of the pest. they were on 9 and 10 weeks so not terribly early. did a super speedy wet trim and chopped them up put them into gallon ziplocks, then they went straight into the freezer for fresh frozen extraction.

over the next two days we took down the rest of that half of the room. it was partly as a precaution, but the timing actually lined up perfectly. CTOG and cody had at least 10 weeks. sssdh, cbdb 1, and moon 4---12, 13 and 14 iirc.

we've been on a disciplined 3 day neem foliar since the first sighting. i think we underestimated the importance of a good foliar IPM regimen in addition to the success we've been having with beneficial insects. we're spraying the prop and foliar rooms, plus the plants still in stretch mode in flower. for that spray we do neem oil, ag-sil, yucca extract, and sometimes a bit of aloe.

picture.php


i kept a few plants ready to reveg. i ended up doing a root prune and transplanting sssdh and cody. keep your fingers crossed! there's still some old cuts in the cloner so i'm hoping one of them will save my ass lol.

11917760_432116506994024_1041841632_n.jpg


today i was reading avianish.mile's thread and the point was made that sst/enzymes could play a role in pest defense through foliar application. duh! chitinase right on the mf'ers! i am not sure it would be good for my beneficial insects, especially the pirate bugs---which are super hard and shiney looking like they are made out of lots of chitin---but maybe with the right timing it would be effective.

any thoughts from my fellow gardeners?

i've done some light digging but haven't yet found conclusive statements about the enzymatic content of malted barley.

my research around chininases is interesting but just starting. i think i'll be incorporating some ideas into practice soon.

even with only four lights on for their entire flowering life i think we got a decent return on all these gals. plus we saved some money in electricity. and most importantly we kept temps in the 76--84* range so the quality of the flowers is intact with gorgeous plump resin heads and delicious aromas. i've vaporized my share of terps in my former closet days during this time of year, and i'd rather have less volume and more quality. i don't much care for shitty weed, and a few extra ounces won't change that.

anyway enough boring nerdy stuff. i've got some pictures, although they're already almost two weeks old!

i'll start off with a nug from one of the gg4 x fbpk. week 3--4 maybe? these poor gals have been a bit neglected but they're backed up and will get another chance. even with the neglect they look pretty fucking awesome tbh.

picture.php


along with the three gg4 x fbpk sisters, we've got two satsuma gals. one got super droughted and is not gonna be a good representation of her potential, but she still wins the smell catagory. it's like those minute made orange popsicles. also in there are two more bagseeds because apparently we fucking love bagseed lol. we've been calling the kushy one in the corner "tangie maybe" and it's from a bag of tangie kosher (probably) my partner got a while back. the other one is bagseed from a bag of lady cane he got a while ago. she's dead center in this pic.
