I dont have a seperate veg room, so they spend 12 hours under a 600w, 6 hours under a 20w cfl and 6 hours in darkness,
My water is treated with chloramine yes, but letting it sit overnight wont do any good as it doesnt evaporate
Nutes are canna aqua vega/flores, ph is about 5.5
The roots have grown through the net pots into the water.
I have grown for 4 years using this water and havent had any major problems
Also i cannot afford a r/o filter
