The sand I bought was labeled "pool filter" sand and was the most coarse I could find without driving all over creation comparing grain size. How can I fix the drainage issue without repotting my plants? There are 1" holes on the bottom for drainage; could I stir it through those?
Elaine, about the fertilizer. Mix it with water, or apply directly to the soil around the base of the plant and water thoroughly?
I've got seedlings that I think are ready to harden off. They have 2 and 3 sets of true leaves. My concern is that I'm going to kill them. They've been in a climate controlled environment wih 24 hours of light since they've sprouted and I don't want to ruin them. Any suggestions, other than the run of the mill answers on the web?
