DWC Sea of Green??

[wman44]

my last grow was an organic soil grow, one plant scrog.
it yeilded about 2 and 1/2 ounces. but that weed only lasted a month and im really sick of paying $50 for a sac of keifed nuggets.
right now im building a cfl cabinet for the purpose of creating the perpetual harvest in order to always have medicine. i've been reading up on dwc and i have pretty much everything i need to get started just laying around. i just have one question.
has anyone used a dwc for an sog?
im concerned with damaging roots when harvesting mature plants.
any thoughts or advice would be greatly appreciated
thanks

You don't have to worry about root damage at harvest time. If you are running multiple strains that don't finish at the same time, yes, you might have issues.
But DWC is suitable for a SCROG with some advanced planning; specifically, "How am I gong to maintain access to the res when the screen is full?" (hint: put the buckets at the CORNERS of the screen and train the plants INWARDS to meet in the middle)

Thats a great idea from Stinky. Also, the res does not need to be under the screen, it should be somewhere outside and fully serviceable. The problem I think is if you are doing this for the first time, how are you gonna get the males out once you discover which is male? That's of course not a prob if you are using clones.

You talking about sog or scrog? If you have a screen and discover males, it's not too difficult to cut them out. That is as long as you did as you were supposed to and provided access to the back, under the screen. Of course it's much better if you can just start with girls.

[herbie the love bud]

I don't do scrog right now for different reasons, but if I were it would only be with guaranteed females. If you don't catch your males early enough you risk disrupting the pollen even more trying to cut it out. So SCROG is really a better option once you have your strain dialed in.

[Opie Yutts]

Agreed. It would be beneficial either way though. You don't really start tying stuff to the screen until you've gone to flower and moved the plants to under the screen in the flower section.

actually if you read the title of the thread you'll see the question pertained to sog, but thank you all for your replies, and to stinky with the root info.
males wont be a problem in the flowering chamber because i'm in the process of building a cfl lighted mother/cloning chamber. with this i will be able to put say, 6 small rooted clones in the flowering chamber, 2-4 weeks later i would put 6 more in creating an alternating perpetual harvest with fresh clones being rooted in the clone chamber.
what i' m mainly concerned with is the size of the plant sites/ netpots or what have you in the top of my dwc. i was thinking of using hydroton in yogurt cups with slits cut in them like a net pot so i could use them to block out light if a site doesnt have a clone in it. would this 2-3 inch cup hold a nice cola ok?
also regarding maintenance of the dwc, i was thinking of using a small submersible pump in the res. to remove old nutrient solution.

[wman44]

well i googled netpots and found out that they are made in 2 and 3 inch sizes....looks like i wont need to use those yogurt cups
hahaha

well one thing to think about is having seperate res for each section being harvested so you can do a proper flush w/ out bothering the other ladies. otherwise yes i have seen it done. If using 5 gal. buckets you can stack the smaller ladies buckets so the conopy stays even. like a cascade. :)

I cannot believe in almost 3 years nobody could or would answer this guys question. He wants to know if you can gro SEA OF GREEN in a DEEP WATER CUTLURE. The answer is HELL YES you can. I used to do it! Because of legal plant number issues I do not anymore, I wish I could.

OK, I had 4x6 foot trays, made one piece lids out of 1 inch polyurethane foam (the pink stuff at home depot) each lid had 72 holes for 3 inch netpots.

on the bottom of the tray I glued plastic clips that would be right uder each hole in the lid, 72 clips for 72 airstones.

At the front of each tray there is a overflow riser made of 1 1/2 inch pvc so the water lever in the tray will stay 1 inch below the bottom of the net
pots. ( this is how the nutes get back into the reservoir)

At the back of each tray is a 1/2 inch pvc pipe fill line with 1/8 inch hole drilled along the bottom, ( this connects to your pump to fill the tray and keep them constanly recirculating) This iece is as wide as the inside of the tray for even flow(NO STAGNANT SPOTS)

One 1200 GPH pump was used to feed nutes to 4 of these trays.

I use a chiller to keep the nutes at 65 degrees, that where I like my nute temps, some may disagree, works for me.

Over each table there are 2x 1kw hps in air cooled fixture, My room was sealed and CO2 enriched to 1500ppm. You can do this just fine with just a good air exchange/ventilation.

The strains I used to get 2+ ounces per plant were, Frostbite from Chimera, Big Blue from the BCSB and Chronic from serious seeds. My buddy still does it this way and grows the SAGE.

@ 2 ounces per plant we got 4.5 pounds per 4x6 table of fat poles! Its really more of a shallow water culture but its the same principle, if you had deeper trays you would go broke filling the system with nutes. I just might have to do this again and post some pics, there is no information I can find anywhere on this technique, its really worth the setup effort, you can control your EC and PH so much better then you ever could in a rockwool SOG setup and there not 500 rockwool cubes to dispose of every 8-10 weeks, only a mass of roots!

SCALE THIS SYSTEM UP OR DOWN TO SUIT YOUR NEEDS AND GOOD LUCK, SORRY IT TOOK 3 YEARS TO GET AM ANSWER BRO!
