DWC ppm

[Mopedstoner]

Good day growers I'm using a dwc system (deep water culture) and was wondering what is the highest ppm I can go using this system before my plant get burnt. I know different strains would have different numbers but I just wanted a general to know ones I get there I know to back off

you can go as high as 1200ppm in dwc, possibly even more. it depends on alot of factors including strain, room environment and size of the plants so its a bit of an open question really.

Ya I figured that. I'm in the high 800 to low 900 range and they are looking pretty good. Just was wondering if I bump it up I don't want to go to high but like what cultivator is saying it all depends. So I'm just going to do s little a week and watch them my goal is 1200. Thanks all for the help I've got 6 weeks left.

ditch the cool tube. they are horrible. I ditched them around 3 years ago and i will never go back. you can cool a dutch barn style ust as easily. no risk of smell leak and no light filtered out.

I keep mine from 900 to 1200 but I ended up with some tip burn in high 1200s. Jack Herer strain at 21 to 28 days in.
