I wish I got that far, lost the plants from root rot, I'm 1 week into starting over will start a new journal when I get to flowering

yea know one helps out on here, with some REAL help you probebly coulve prevented and saw the root rot comming

Hi there.....I'm a newbie on this forum, you are my first contact (congrats! ha ha ha)
I'm doing DWC right now in tote tubs, like your set up....only I'm using Sensi A+B, Aqua Shield, Hygrozyme, and rapid start root food.....

I'm 100% pleased with the results, but the price is killin' me.....it's about $150 worth of nutes for 3 maybe 4 grows with two 13 gallon tubs.
I've had good yield with only a 126w T5 flouro, then finished with a 150w HPS. Yield increased dramatically with a scrog setup on my last two grows, and I'm finding out how critical the timing and maintenance is with scrog....but it's worth it

My friend in Canada has been telling me he uses only plant prod 15-30-15 all the way through the life of the plants, and has XLNT results with a 400w metal halide bulb. He says he uses it at about 1/5 the strength it says on the container...

My (long winded!) questions to you are....did you have a good harvest, good flavor/yield/size, etc...and would you say switching over to plant prod foods would be a good idea for other folks trying to save costs with DWC setups? (without sacrificing quality, of course!)

Thanx,
