hmm, place your thermometer between the plant and the light and see what it reads there after a few dozen seconds. if it's around 90 or above, I'd raise the light.
get a piece of glass and some wire, make two big circles of the same length out of the wire, hang them over your light, then hang the piece of glass on the two wires
or you could get a cool tube, but thats a chunk of change.
that's not true. I can find morning glory at my local florist almost any time of year, the only illegal part is if you extract the drug from the seeds.
