Your going to kick some ass! do you have a controller that keeps the temps lower during lights off? are you running one burner or two to get to 1100ppms? you said you were looking for a dehumidifier, There is a guy that has a warehouse of overstock stuff in rancho cucamonga area im not sure how close you are to that.. But i got a 90 pint for 120 bucks brand new. I know there alot more at home depot, hit me up if you want that guys number.

Currently we are hitting around 67F lights off with no controller. I like that! I'm just running a single 4 burner that's PLENTY big enough for our sealed room size. I could be twice as big and still use this little burner. It's when running CO2 non-sealed (a bad idea) that one could need a bigger burner. We installed 140 pints worth of de-hu yesterday. That dropped the RH to 45%. Today I'm routing the de-hu drains to the nute res. Between the split ac's and the de-hu's, we're making around 30+ gallons of water per day! This works out to about 50% of what I use to water everyday.

I would still like the guys # that has the overstock on ac'c and de-hu's.

Sounds awesome! perfect room! and your running one 5 ton, and venting lights? how many inline fans are you using? My buddy uses the wings so he has to use two 5 ton ACs for 20 lights, i was trying to figure out how much more power he uses doing it that way.

that de-hu guys number is 909 908 6006 his name is Clyde. he has alot of shit there, he said he doesnt get alot of mini splits though :\.


i just got a 2ton mini split yesterday, if you know anyone that can hook it up/ charge it and is down with the cause, i would greatly appreciate it. Unfortunately being younger, i cant think of anyone that i know of that can do it and im sketched about calling a local AC and electrical guy.

Hey CG, what size dehumidifiers are you using and which type if you don't mind? When I've looked at some before, it seemed like anything at 45+pints/24hours said it was running about 500-600watts+. Is that normal? It sounds like a lot of power to me.

We switched to sealed, enriched, and air conditioned 3 days ago. Holy shit! I'm so exited I could just explode. My daytime temps are now 79.5F - 79.7F. The inverter mini splits are able to slow down the compressor, rather than starting and stopping. This makes perfect temp control possible. The Sentinal CO2 Controller is keeping the level between 1000 and 1100ppm's. If I crank the A/C's I can drive the temp as low as around 75F with lights on! We have plenty of extra cooling power. My RH is hovering around 50%-60%. I'm adding a dehumidifier today. While those levels don't bother me, I would like to be able to lower it during the night a tad. The A/C's dehumidify a bunch...producing 10 gallons each of water every 24hrs.

The A/C's are Gree 2 ton units. They are 22 Seer!!!

I had plants at 1 week, 2 weeks, 4 weeks, and 5 weeks when we switched. Now we should be able to determine at what week the CO2 makes the biggest difference. Look out Commercial J...I'm nipping at your heels.

That is some impressive fucking process control man. A delta of 0.2°F in a grow your size is amazing. I know process engineers that would be green with envy.
Also I agree 100% that a few hundred bucks on a lawyer is the best money that can be spent on setting up a big grow.
Keep up the great work man.

Hi CG

I read that you did some pruning to get to 4+ oz per plant. So an indoor plant that has leaves taken off it will produce more than one that is not touched? Can you elaborate on your pruning process. I would greatly appreciate it. Do you take all the fan leaves off? Do you supercrop, tie down or FIM etc?

Also, I am in the process of retaining a good MJ lawyer and possibly start a small collective. CA law states that when forming a collective you have to apply with state. Did you apply with the state when you formed your collective?

Many Thanks!

I'm pretty sure I detailed the process a ways back in the thread. Basicall, I remove most of the inner fan leaves on the upper 50% of the plant during early veg and keep doing so till harvest. Allowing light deep into the center of each plant developes more branching and bigger buds on the lower plant. Plants that once yielded 2 oz each now yield 3 oz each, with several 4 oz plants in the mix.

Whew, just finished 4 days of off and on reading of the greatest commercial grow diary ever! CG - big time kudos for doing this and for your updates, knowledge, patience, common sense and honesty to a very mysterious process. If this was the only grow diary that existed, someone could learn everything they need to start a successful operation.

I envy you as I'm on a 2 grow year hiatus and came to RIU for a fix, a thrill, as vicarious as it is to read about other growers experiences.

I have a question, early on you started DWC with Godzilla and then even started a whole RDWC system but then moved on. What happened? I've always loved DWC and modified version with DWC/Sprayers (low pressure aero). Once dialed in, all waterings are on timers and in my case, far less garbage for landfills every harvest.

No question that, once dialed in, RDWC is a very powerful growing technique...more powerful than soiless. But, doing it right requires quite a bit of complexity. With that comes more risk of a failure costing you the whole crop. We have chosen (like most commercial growers we know) to go the safe route. Money is best spent on dialing in the perfect atmosphere. If everything else is perfect, yet you still need better yield, going RDWC may be the ticket. Just remember that the grow is only as strong as its weakest link. I may go RDWC someday. But, not until I am matching my friends soiless yields. Only then will I know that I've maxed out my grow's potential with soiless. We are no where near at that point yet.

really inspirational thread man. have enjoyed reading through it over the last few days. props on the setup.

i started off trying to go hydro (big mistake) but i'm on the right path now. using sunshine #4 with worm castings. gonna try mixing in some coco the next time around. using advanced connoisseur with a few of their supplements.

thanks again for sharing all this info.

^ i agree with that 100%. why move on to something else, if you haven't mastered mastered what your doing now.

it probably says way back but... if i remember correctly your vegging with cubes..4 or 6 inch? are you doing a flood table for those?

i want to setup a 4x4 table for veg just to see if it maybe something i am interested in the future. My buddy does two of them and floods 3 times a day.. both tables are under 1k halides and i have never seen such even growth in veg. his canopy is tits everytime. It seems that when you got everything dialed.. veg really plays a role

Veg is everything. Spend enough time with a strain and you'll be able to predict yield from each plant before it goes into bloom...just from the look of the veg job.

I do not use flood tables. Everything we do is top feed, hand water, drain to waste. We use 6" blocks in veg then go to 2 or 3 gal pots filled with 2/3 rockwool croutons and 1/3 #4 perlite. While the Hugo blocks saved tons on labor, the crouton mix grows better plants.

I would love to see a commercial DWC or Low Pressure Aero system. I've seen tremendous results on a small scale.

im not too familiar with the crouton mix im going to check that out. does that just help with better with air for the roots? my buddy puts hydroton in the bottom of his buckets, is that along the same lines? Ill have to give that a try next batch, im just doing all sunshine4.

bravo on hand watering every little lady in veg. thats got to be a pain in the ass, but beneficial in the end. how many ppms are you pushing late veg?

have you tried 5 gallon buckets? from a 6 inch cube into a 3 gallon seems like a small jump to me. probably makes them too bushy you wouldnt be able to fit as many?

^ definitely not trying to tell you what to do. just curious

Crutons are made by growdan and like cg said they do grow better plants! Has to do with better aeration. I like the idea
Of perlite, cg do you line the bottom with it or mix it?

Oh no! Say it ain't so LOL you just got me switched to Sunshine Mix #4 but now perlite and rockwool! For the last 2 seeds I germinated I did a side by side in Rockwool vs Sunshine Mix #4. I germed both seeds of the same strain one in Rockwool and one in Sunshine mix. The one in Sunshine mix was twice the size of the one in the Rockwool cube so I converted.
