I'm using CFL's right now(going to be upgrading to T5's soon). The temp is about 80 degrees F, with between 50-60% humidity.
Soil is a mixture of seed starter and cactus soil(good drainage). I am not using any nutes right now. Just whats in the soil, and purified water.
I know these plants need to be switched into bigger pots, but due to light issues, I am waiting on the T5's before I plant them into their permanent pots.
I will be switching out the ones in the cups today though.
