50/50 Spagnum Peat Moss and Vermiculite is the soil mix I have been using.

Germinated seeds in 1/2 gallon pots, been under six 23 watt CFLs for a total of a little over 10,000 Lumens. Running 19 hours a day. Have a nice little fan in cab. Cab is l-12inches by w-12 inches by h-40 inches

4 of the CFLs are the regular yellow and 2 are Daylight.

They get about 15 oz (just enough to make water come out holes in bottom) pure, Brita filtered water with a few drops of Superthrive in it every time I water.

I usually have to water about 3 times a week.

I try to keep temps in the 70-80s, but sometimes they do get to 90 in the afternoons if it is a warm day and I am not home to open cab door.

I know hitting 90 slows growth to almost nill, but this is not the norm. For most of the day, at least 13 or 14 hours of the day, and all day on cool days, temps are in the 70s-80s. And they usually drop to 60s- low 70s at night.

I am getting a window AC soon for the room, hopefully it will cool the closet too.

Anyway, those are my specs and here is the prob. Growth is extremely slow, almost non-existent. Plants look healthy (although one is a pale lime yellowy green) but are just stagnating at a few inches tall.

Is this likely a soil problem using just peat moss and vermiculite?

I really cannot image the problem is the temps, as hitting 90 is rare and besides, plants would experience much worse outside.

I think I should change my medium perhaps? Any known problems with peat moss and vermiculite mix?

I checked Ph with 2 diff meters (a passive one and an electric probe one) and both said between 6.7-7.0 although I have little faith in the accuracy of any Ph test method I have yet to find in any garden or hardware store.


Any diagnosis for this stagnation?
