Within the next year I hope to have a 6' x 5' room available for me to grow.

Entry to this room will be gained through a hidden door unlocked with a remote control that automatically opens and closes the door. Here are the two video's that show what I am speaking about in regards to the remote control...

As I have drawn this is beyond the limits that I would use the room for, but this is what is would be capable of doing.

I have decided to use DWC SOG using LED lighting. I already own two 150 LED Bars (4" x 40"). They are full spectrum, meaning;

50% 660nm deep red
10% 630nm red
10% 600nm orange
10% 3500K warm white
20% 460nm blue

you can check out what they are currently (legally) doing with a link in my sig, back to the room...

The DWC tubs I currently use are in my plans. They are called 10 gallon storage tubs. With 2 - 6 inch net pots they will hold 5 gallons of water and this is the method I currently use with veggies and the method I previously used scrogging...

However, in SOG and using the 4 plants per sq ft plan I will use 2 or 3 inch net pots with 8 plants per tub. 3 tubs per light, meaning 24 plants under one LED bar. And if each plant can just produce 7 grams dry that would total up to 168 grams or 6 ozs... over 1 gram a watt. I think it's very possible ;)

Also in the room I would need a clone and mother area under an LED bar or flouro's. This area would need to be framed out and basically turned into a cabinet, with doors. Or much easier, I could use a large piece of black pleather with velcro to attach it to a frame. This way it would prevent light leaks but could be completely removed when working with those plants. The reason I mention this is I have a friend who used to use this method, as his veg and flowering were in the same room.

I would also want a breeding cabinet or framed, velcro'd, black pleather area.

In the sketch up it's drawn with a mother/clone area, a breed area and the two lower areas for growing smoke. if you wanted to eliminate the breeding area, you could theoretically harvest 168 grms every 20 days, or over 1 lb every 60 days !!!! :eek:

so with a 4' x 5' footprint as i have drawn i think this setup could yield almost 7 lbs a year. HOWEVER, keep in mind you would be above the federally mandated number of 100 plants. This is a risk I do not want.

And since I can only smoke about 1 oz a month, I will not need more than 24 plants for smoke, 24 clones, 6-8 mums and 1-24 plants breeding. At the very most with everything in full operation; almost harvest, clones, mums and 24 in breeding, I would have at most 80 plants. More than likely most of the time I should have not more than 30-40 plants at a time... In my state the issue is weight anyways...

For odor and ventilation I plan on exhausting into a boxed area where the air will be treated with ozone before passing across a carbon scrubber and exhausted outdoors. The air conditioning duct in the room will be the passive intake into the sealed, negative pressured room...

Ok, so what do you all think? Suggestions, comments, compliments :dunno:

sorry, but I don't see you getting anywhere near those yields with LEDs.

well i guess we will have this thread to come back to if and when that does or doesn't occur.

in the meantime, google "LED GROW SHOW" and check out stra8outtaweed's plants and yields using these exact LEDs...

what is so unrealistic about 1/4 oz per plant?

i think it's very doable..

with that said ^^^^ i've already had a change of heart when it comes to the room design...

here's the new one. more floor space to work on the plants and an exhaust/ventilation system with ozone gens and carbon scrubbers.

the 4 black holes represent 4 PC fans exhausting into a chamber with an ozone generator. the positive pressure created in this chamber will force the exhaust across a layer of carbon into a secondary chamber where o2 cleaning and carbon scrubbing occur a second time. on the opposite side of the last carbon scrubber and not pictured will be another fan creating the necessary umph to get the exhaust out of the room and through a roof exhaust ;)

if that won't clean up the stinky stuff, i don't know what will...

I have my doubts on a gram per watt as well ,seems like a waste of money on lites when you could do better with HID IMO

I also see possible probs with 8 plants in 10 gallon tubs ,Its tough enough with 4 in a 10 gallon during veg.
I would go no less than 16-18 gallons with 4 plants maybe 6 but res size is critical with multiple plants.

i've been the HPS route before, did just fine. won't miss the heat...

i don't want this to be a LED vs HPS discussion. that decision is already made.

this problem i can deal with. i can easily upgrade the size of my reservoirs.

okay after reviewing stra8outtaweed's grow again (seems like that web site is down right now) he obtained a .88 gpw rating, producing 528 grams with 600 watts of these LEDs. so he produced 132 grams per light.

so using a .88 gpw rating this setup should produce 396 grams every 60 days or about 5.3 lbs a year, instead of the 7 i projected. this would mean each plant only produces 5.5 grams and not 7 grams.

this in fact may be a bit more realistic. the reason i say that is from what i have seen, LED's seem to need about half the power to produce a similar crop. in other words, the 2 - 150 HPS lights that i used to use to produce 5 ozs should almost be equaled with 1 LED (each LED would produce about 4.7 oz under the .88 gpw rating...)

with all that said, i still believe the 7 grams per plant is doable with good growing conditions.


and with all that said, it's pointless to me as i will only be using a portion of what this area could really do...

i am really just looking for an efficient growing area, that allows me to clone, keep some mums and play around with some breeding and selfing....

No biggie on the led .We'll leave it at its "hard to teach an old dog new tricks"

I bet with cocoa in a sog you could hit some good #'s,I'm thinkig of making the switch fromm dwc.After seeing a grow less room less work ,more plants

I like your idea of exhausting into a box with an ozone generator... it gives time for the air to mix with the ozone.

BUT...

I would run the exhaust through a scrubber *before* buffering the air thru the ozone percolatin' box.

I'm considering a box, but for my ballasts and scrubber... might one day adapt your idea to the exhaust side... but I don't think smell will be a problem with two scrubbers or one oversized... slow air movement and negative pressure should do fine.

the EXHAUST BOX is a great idea. I incorporated it into a cabinet I used to grow in. The link is in my sig. The air was captured in a 6 sq foot chamber where is was attacked by ozone. The positive air pressure in the EXHAUST BOX pushed the air across 2 inches of carbon while leaving the cabinet.

Cleaned up every strain I ever grew in it except Afghani, which was some stinky shit. Never got a chance to grow out my Skunk seeds but I would bet that would have presented problems as well...

but yes overall, using a grow chamber exhaust fan to create negative pressure in the grow are and positive pressure in the EXHAUST BOX works well...

no problem jm420, should these LEDs do poorly I would revert back to HPS in a second, but this is what they are capable of doing: :eek:

these are 3 pics from stra8outtaweed's grow with these lights...

btw, what advantage would cocoa in sog give me? Please explain, maybe that's the setup I need... In my setup the DWC will give me 4 plants per sq foot...


again, these pics belong to stra8outtaweed...

I found one of that guy's older videos about a year ago when I was looking into this stuff.

The biggest problem I see with his idea is that unless his basement is a windowless, doorless slab that is completely covered by soil/bushes, you'd have to be retarded not to realize that he has a basement and once you know there's a basement you know that the stairs to the basement are probably in/near the kitchen. The fact that there is molding all around the "bookshelf" (who builds a recessed bookshelf in their kitchen? He should've called it a pantry.) makes it look like the doorway that it really is.

If that guy really wanted to go stealth, he could've built the "bookshelf" INSIDE that space behind the door, so that it covered the steps. Then with some shelving all the way around, it would look like a food pantry.

If you do build one, please let me know. I'm very interested in secret doors ever since I was a kid.

Here's my 2 cents, sorry to be a downer.

First, from my experience with cabs ... it's easier to cram things into a space in Google Sketch-Up than it is in real life. What you're planning looks pretty tightly packed. Now, I know some folks like Anti pull off great, tightly packed, stealth cabs. Those are the exception.

Second, I have doubts about your ventilation plan. I just think the idea you have of PC fans blowing into a chamber, and hoping the positive pressure created will push through carbon, etc, is not going to work, and that you will end up with almost no air exchange.

Third, you mentioned you pulled 5 ozs off 2x150w hps. So, 0.5g/w. And now you expect to get 0.8g/w+ just cause you're using LEDs? I'm not going to say LED's are better or worse ... but if you're only pulling 0.5g/w under HPS you have something holding back your yield - whether that's genetics or technique I can't say - but I can bet that you will not see an increase per watt switching to LED.

That's my thoughts, don't mean it to be discouraging, just realistic (imho).

not discouraged at all...

here's a cabinet i used to grow in. i understand tight and compact.

i understand stealth...

and i understand my exhaust idea, it was created and used in this cabinet. including positive pressure pushing the exhaust from the exhaust chamber across carbon... (on the left)

picture.php



link in my sig has more info as this cabinet continually evolved becoming more simple with each grow.

i can't wait til i can grow again ;)

i thought about this design in regards to the EXHAUST BOX. I can compare it with what i had done in my cab...

CAB:
passive intake --> 18 sq ft grow chamber (neg pressure) --> 90 CFM PC Fan --> 6 sq ft Exhaust Box (pos pressure) --> thru 2 inches of activated carbon. Air changed 5 times a minute in the cab based on the fans CFM rating. The back pressure from the carbon probably lowers that a bit.

ROOM:
passive intake --> 222 sq ft grow chamber (neg pressure) --> 4 - 90 CFM PC Fan (360 CFM) --> 12 sq ft Exhaust Box (pos pressure) --> thru 1 inch of activated carbon --> 4 sq ft Exhaust Box (pos pressure) --> thru 1 inch of activated carbon --> another inline fan or PC in needed. Air changed 1.5 times a minute in the room based on the fans CFM rating.

So it may that I need another fan at the end of the chain. If I do I will build it into the Exhaust Box space. If I need stronger fans I will use them, but I am hoping multiple PC fans can move the air enough. Really no way to tell but to build it :D

Impressive. I'm sure you'll build it just fine seeing that. I didn't have as much luck, and when my living situation changed I just switched over to tents, easy and quick.
