Hello,
i grow hydro using rotating sprinklers for seedlings and bubblers for plants over 2 weeks old.
So when i use rotating sprinklers, the light is 2 fluoros cfl and i have no problem.
After 2 weeks or so, i change the plants for the production tent where i let them 2 more weeks under 18/6 of lights, using DWC technic.
There is plenty of air, good air stones, very good PH, good water temp and low EC. There is a fan and an exhaust.
The light in this tent is LED's, High power COB's that gave very good results in the past.
The problem is that after the change to bubbler, after 12 hours of light, the leaves are droopy as if they did not like the light, and they recover after 6 hours of night.
And this is every day, they are not happy at the end of the day and recover at night.
I changed for new led's, i thought it was because of old led's, but the problem is the same, it does not fix the problem.
The plant's thrieve anyway but as the plants are not happy, i'm not happy either.
Do someone have an idea ?
I've been growing this way for maybe 15 years, and never had this kind of problem.
