And get the cups RIGHT up to the light. The leaves of the plant should be about an inch from the tube.
You need another tube in there pretty soon if you are going to grow under tubes. I consider a pair to be the minimum; the multiple points of light are really beneficial and you'll see how when you add it.
Temp is good. Ventilation is necessary. A small fan circulating air IN the cab, plus an exhaust removing air FROM the cab, are both needed.
what about now? no seedling has come though the dirt yet. should i cut the cups and move them closer to the light or should i leave them be and put a bowl over the cups until the seeds start to come out?
