I try for 9 plants per light - doesn't always work that way though. lol I start them off with Superthrive, and at two weeks, add Molasses, as well, and they get put into their three gallon bucket. This is their final home. At this time they go under the MH light.
At three weeks, if it's a strain I'm topping, I top for four colas. Finish vegging to six or eight weeks, depending on how big it is.

Nothing much to explain here. They flower, lol. No more than nine plants per light.
In either room, airflow is great, never had a problem with mold or mildew, the occassional fungus gnat in the veg room (from the soil) that I treat with Neem Oil.
That's pretty much everything! If you need any other details let me know.
So just the water? That alone is causing the lowered yield? I plan on an RO system as soon as I can afford one, but meantime...
