Less than a month and a gallon of Nutes??!1 What are you using?

 

[mikey]

Yes...using Dynagro using t-5 lamp set up with light mover. Grow light is four bulb 2' 100 watt for veg. When I switch to flower will be using 315 watt CMH.
Have you ever used Kratky method? This my first time growing DWC without air stone. Have always used airstones constantly and changed water weekly

Not really no. I'm still trying to wrap my head around a gallon of nutes for 3 plants in less than a month, lol. Having used DynaGro, that must be some method/system you use. Now I gotta go look it up,..

No boasting here... started plants from seeds in rockwool, placed them in beer cups and by second week started feeding them 1/2 strength dynagro in cups filled with perlite. by the 26th of june with enough roots showing placed them in 5 gallon buckets with perhaps 1/4' of nutrient in netpot. filled netpot with hydrotron to cover rockwool. Plants are now just bumping bottom of scrog screen! What I'm wondering now is how much to refill buckets....cause the plants will start using more water more quickly as the root system increases. I'm guessing that when they use all but the last gallon I'll dump what's left and add two gallons. This should leave about 1 1/2 gallons shy of being full. Is that enough of an air space for the air roots? I don't want to drown them!
