what do you guys think is the best setup for stealth?

i am thinking about insulated ducting.

but as far as hyro, i was thinking about DWC/SWC, but then you have the air pump running non stop and the sound of bubbles breaking surface.

what about ebb/flow? its just im limited on headromm as im in a cab.(specs are 2 posts up)

what do most of you guys run in your 250 cabs?

Mine is about the same size flower chamber 39 1/4" H x 25" W x 20" D
I have the Vortex 4" in another compartment sucking out the back into insullated duct and into a carbon filter works great and is very quiet.

Sounds like a central air vent or a desk fan on low as far as the sound level.
My temps stay between 78f-82f room temp is 70f-72f.
The space is too small to put the fan inside the same space with the filter.
If you choose to run like I did then I say go with the 6" Vortex which is also 49 dba as far as sound exactly like the 4" with much more power and use it on a speed control for lowering the noise further.

Here's my 250 cab

 

[VerdantGreen]

hi all - first i should say thanks for all the great info in this thread - very inspiring!

i have a new 250 cab with a diamond reflector , 24 X 28 x 4ft high , organic soil. personal medical grow.
finished my first grow a couple of weeks ago - a dry run with lst (i wanted to do this for the comparison before i went modular scrog)

got about 5 and a half oz dry off 3 of my plants (2xblueberry and a dolce vita) which i was pretty happy with. the fourth plant was a very runtish flo that i got about a quarter off even though it took up a quarter of my cab !!

so the maximum yield from a 250 is about 8-9 oz is it?

ill have to try and get some pictures once ive worked out a secure way to upload them etc.

new on the modular scrog is NL (atomic), Sharksbreath (DNA), Martian Mean Green (DNA) and burmesexFI. trying to grow this pretty full range of sativa to indica together in a scrog is a challenge but also it's teaching me a lot about the different stretch etc. its going quite well. the plants came from a friend all together and i had little choice but to run them together too.

cheers
V.

hey man what are you yielding with that setup those look like nice nugs what strain and how dense are those buds??

 

[dragongrower]

great pix under the 250watters!!
I my self have one of those too... Corrently not growing anything.. But it will come..

 

[SkunkyDemon]

Wow nice harvest! I love those pics from the 250watters. Nicly done.
Keep those sweet pics coming.
Peace

 

[smokeymacpot]

feat. some 250W nugsss

keep it rasta

thats a pretty bud, what strain is it ?

 

[Bill O'Reilly]

thats a pretty bud, what strain is it ?

The strain was gifted to me I have no idea of its origins. It acts like a pure indica. Some have suggested it is purple kush or maybe northern lights.

 

[luv2garden]

Wretched,

Not sure of yield it's curing now and I don't own a scale it's for personal use but I'd guess 4-5 oz. dry.
The strain was Bogbubble (bubblegum) and the budz are frosty, fruity smelling and dense but not like C99 hard rock golf balls more like Papaya or Blueberry texture not airy but not hard rock either right between if you know what I mean.
It was one plant that I vegged for 2 months and she's a huge giver.
The test bud was a very couch lock, heavy head stone which I use as a day ender

Very impressive Luv2garden, what are the details of that grow, veg time, medium, strain, nutes, seed or clone etc..? Looks like you took in quite a haul, what was the final weight?

 

[limey]

got about 5 and a half oz dry off 3 of my plants (2xblueberry and a dolce vita) which i was pretty happy with. the fourth plant was a very runtish flo that i got about a quarter off even though it took up a quarter of my cab !!

I squeezed only three quarters of an oz more from my grow last year. Reckon your 5.5 is pretty respectable

so the maximum yield from a 250 is about 8-9 oz is it?

Sounds about right, a gram per watt. That's what I am aiming for this year. Will be trying some White Rhino.

I reckon - all other things considered - that having them in veg for long enough (at least 3 weeks) is pretty crucial to achieving a high yield. A good hydro set up really helps too, in my experience.

 

[limey]

but as far as hyro, i was thinking about DWC/SWC, but then you have the air pump running non stop and the sound of bubbles breaking surface.

I run an adapted aquafarm driven by a water pump rather than an air pump. Works a charm. Would be very easy and inexpensive to build the same thing yourself. You would need:

A small water pump, for an aqarium or small "water feature"
A 5 gallon bucket
A 10 gallon bucket that the 5 gallon bucket can sit neatly into/on top of, so there's plenty of room below the 5 gallon bucket to use as a reservoir.
A piece of plastic/rubber tubing to fit the small water pump outlet
A T-piece fitting to join that to...
... a piece of plastic/rubber tubing to the other piece of tubing

Drill a bunch of small holes in bottom of the upper 5 gallon bucket, with one big hole for the piece of plastic tubing that will be attached to the pump

This piece should be cut to size to run from the pump in the bottom bucket, through the hole an up to the level of the top of the upper bucket

Use the T-piece to attach the other bit of tubing to the top of the first bit of tubing, horizontally, in a loop. Punch some holes in the downward facing side of this loop.

So all connected up.. the pump in the bottom bucket (the reservoir) should pump the water up the vertical tube and round the top-end horizontal tube and out of the holes, down into the top bucket...

You fill the top bucket with clay granules, such that the water runs out top-end horizontal tube the holes and down over the clay granules

You put your plants in the clay granules

You put your water and nutes in the bottom bucket

That's it.

I run this 15mins on/15mins off during the hours when the light is on. Works a charm

thanks for the feedback, limey - i will try and put up some photos when i can work out a safe way to get them online (any threads about that??)

i was encouraged by the yield in organic too. My Blueberry is a good yielder and not fussy in organic which helps, the dolce vita is a power plant cross and grew well but i still prefer the pp i think - got a cut of that now .
i think the modular scrog ive started now should help too as ive only got about 4' height.

 

[luv2garden]

Veg Time= 2 Months
Medium= Fox Farm Ocean Forest Organic Soil
Strain= Bogbubble (bubblegum)
Seed or Clone= Seed
Nutes= Bcuzz Nutrients
Final weight= Guessing 5 Ounces dry no scale

thanks for the compliment!

 

[ixnay007]

As I said earlier.. harvested, and I took pics (about 2 weeks ago )

 

[ixnay007]

Oh, it's a 250, but no longer HPS, I'm liking the CMH, although I think it may yield a bit less.

Plam tree plants

Plam tree plants

Hows everyone doing? Good I hope. Dropped by for little input.

I am running my 250 but decided to add a little more light to the mix . I hve a homebox s 2x2x6 and added 2 42w cfls 2600lumens at 2700k, 1 23w cfl at 1750lumens @ 2700k and 2 23w cfl uva/uvb reptile/lizard lights from the pet store putting out 5.0 uva/uvb rays. Read that uva/uvb rays are good during the bloom/flower cycle to help produce moe resin and hairs due to the radiation like effects of the bulbs. Can say that since putting these two bulbs in the tent i have seen a change in the bud production. The areas on the plant in the most direct path of these lights have shown significant hair prodution over the other parts of the plant. I have 3 plants in the bloom tent. 2 Super Lemon Haze (1 showing the sativa pheno and the other more of the indica phenos) from Greenhouse Seeds and 1 Barneys Farm Nightshade (This Plant is crazy Big leafed indica, even from early veg the leafs are huge i mean the size of fat basil leafs each part of the leaf not just the whole leaf .)

So this is my first true grow and have noticed some strange growth with my plants (not bad). I know everyone has there own tecnique but i have yet to see any plants like mine on any grow forum (grasscity, icmag, and here). For the best explination here goes.

Started with 16 seed and had never grown before and had terrible problems with the time from cracked seed to planting and sprouting. I could get the seed to crack but never sprout. I mean i tryed everything - tap water, ro/distiled water light no light, i mean everything.
So in the end what worked for me is the compleat opposit of what everyone suggest on these forums. For me to get past this stage here is what i did.

The day i put my seeds in papertowels (germed in wet paper towels sealed in a ziplock and set on my dresser) I also presoaked my rockwool and hydroton in a pre mixed gallon of 1/4 strength nutes)

PBP Grow, Calmag, Liquid Karma, Sweet, a touch of B-52, and Mycos - Stared with voodoo juice but now use humboldt nutes myco madness.

the next night all the seeds had cracked and it was time to plant. shook out the rockwool and drained the hydroton. Next instead of waiting for roots the plnts went directly into my dwc (at 300ppm/tds 198) with water filled to the second notch on the bottom of the net pots. Next i place some small plastic containers over each net pot acting like a humidome for each plant. Once the plant had removed the shell (sometimes with some very crafull help) and started on its second set of real leafs so the third set 1-water leaf - 2- 1st set of feeder/fan leafs - 3- 2nd set of fan leafs i removed the domes. This was all before the ddition of the cfls in the tent - so just the 250 was in there at the time.

This is where it gets different. i wanted to run only 2-4 plants (currently 3 plants) insted of the six on average for the size. I also wanted to top, supercrop, and lst all in the same grow. Didnt start this way but this is where i am at now. I started with topping my plants so as to keep them short bushes so the plant takes up the area of two. next i lowered my 250 to 4-6 inches above my plants just above the point i could feel the heat - so as low as i could go befor feeling the heat of the lamp. In doing this the plant remained short i mean short. I veged for 6 weeks from 3/3 - 4/12 before swithcing to 12/12. At this time the plants were only 9-10 inches tall max. On 4/3 i changed res water and damn near killed the plants ph was at 4.75 over night. Did another res change ending at ph 5.75 with ph nute lock out and over watered plants. cut off all affected plant matter and reveged till 4/12 when they recovered with all new leafs. 4/12 finallyswitched to 12/12.


because of almost killing the plants i ended up supercropping them when i removed all but the new grothw shoots. So at that point they had been topped and suppercroped, well as they recovered more for the first week of 12/12 i noticed a shit ton of growth. Worred i would run out of room and end up with a lot of smaller bud, i decided to lollipop all the brnches to one node below each top (each plant has a min of 12-16+ tops)
after this i added some tiedowns to a few branches and instaled an area for My scrog screen. Which will be installed in the next day or two as the plants are starting to reach the area designated for the screen.

So Lets Recap- Plants have been
1- Topped
2- suppercroped
3- Lollipoped
4- LSTed
5- and soon to be screened

in doing this my plants are crazy looking I mean they looked like mini trees. one plant my largest is different. i have net pot covers and straigt out of the top there is not really a stalk/ stem it branches out right out of the top.
the other two ave about 2-3 inches of stalk before the branching out. at each section of the plant where growth sprouts from the branches are swollen i mean nottie just huge. They have finnal reall started to strech and brought a friend by that has his own plants- to take a look and tell me what he thinks- This is whyi have posted he told me that he had never seen a cannibis plant that looked like mine - not in person or on any video he has seen. And i should post a video and pics to see if anyone has any input.

Now i know that i have tryed to much on my first grow (simplest is easyest and learn the basics), also if in the end crop is no good or small i will have a hrder time narrowing down what might have been wrong, but i am a really fast learner and like to experiment. No excuse! but ta all i got. so if you have any ideas on the possible outcome or ideas please let me know.

To late for pics as it is past lights out for my babies but i will post some tomarrow to give you some visuals to go with this long post.

It can.... mostly the "blue end" promotes leaf growth - you will notice that outdoor plants have more leaf as they are exposed to a balanced light spectrum throughout the grow. What you wil have to figure out is whether the extra wattage (and so spend on electricity) is really worth it. Some people swear by blue end top ups. Myself, I have never really seen the point: if you veg for long enough in the first place, I reckon you have set the plants up properly for flowering and a HPS (especially and enhanced HPS) will work fine.

Started with 16 seed and had never grown before and had terrible problems with the time from cracked seed to planting and sprouting. I could get the seed to crack but never sprout. I mean i tryed everything - tap water, ro/distiled water light no light, i mean everything.....

Have you tried shaking the seeds for a minute in a matchbox half filled with coarse sand? helps to weaken the shells on the seed, they will shuck more readily when sprouting.

Myself, I swear by presoaking in water + rooting solution and a light solution of hydrogen peroxide (works as a fungicide) for 8-12 hours and then planting directly into rockwool cubes that themselves have been presoaked in pH adjsuted water/light dose of veg nutes. Put them in a propagator for a few days until established, then in to the rig.

Your nute mix looks like overkill to me but if it works for you, it works for you, so fair play.

So Lets Recap- Plants have been
1- Topped
2- suppercroped

4- LSTed
5- and soon to be screened

Question in one word: why?

1. you have vegged for 6 weeks plus. That's great if you want to grow monster plants but it uses alot of electricity. If you have used this time to develop a really huge SCROG (like 1 metre sq ; 3.3ft x 3.3ft), for example, then this makes sense but I dont think you could light a scrog of this size effectively under a 250w, you would, more like, need 400w or, better still, 2x250watt lamps.

2. the most likely reason that a the plants "are crazy looking I mean they looked like mini trees" is that they are very stressed and distorted from all this manipulation. The best thing you could do at this stage is leave them well alone for a week or so, feeding them gently and leaving them to stabilise a bit. Then flower them off.

I reckon you will get alot of small-medium sized buds from this grow. You risk ending up with a very crowded grow space so I suggest you remove the branches from the bottom third of the plants when they are two-three weeks or so into flowering, to promote growth at the tops, where they get more light.

Sorry to be a bit cynical, mate, and I really do hope it all works out for you. As discussed earlier in this thread, your benchmark for yield should be a gram per watt - the closer to that that you achive, the better you have done. If you wildly exceed 250g under a 250watt lamp, you have done very well ; if you get less than 125g under a 250watt lamp, you should revise what you are doing.

Next harvest, I suggest you keep it simple: stick to LSTing and a SCROG if you want a flat profile. Veg for 3-4 weeks... put em in flower, that's it. Simple, quick, inexpensive. Focus on keeping stable, consistent flowering conditions and be patient with your harvest time.

As many great men (and women) have said "Nature doesn't make mistakes, people do" so it would make sense to say that messing with the plants less and creating conditions that most closely resemble a natural grow will give you the best results.

good luck

this is a pic of my 250 personal med cab, organic soil, modular scrog. 34 days.
im quite pleased with the canopy for saying that i have 4 different strains that had to be flipped at the same time.
back left is NL (this was the least stretchy, couple of gaps in the canopy there)
front left is 420 (burmese xFI )
back right is Martian Mean Green
front right is Sharksbreath.,

good thing about modular is that you can still get the pots in and out and that you can adjust the height of each screen.

Very nice!! Will get humid though. Hope you have good extraction, your NL will not like it humid, I reckon.

Good stuff though...
