put the sprout in root first. cover with about 1/2" of dirt, water lightly, then put it under the fluoros. and keep the fluoros about 1"-2" away from the plants at all times
Well u can´t ever have enough light but that will sure get u started, u can do a whole grow from seed to harvest with fluoros.
If u can add a few cfl´s to those fluoro tubes u already have, cfl´s are cheap easy to use and u can place them almost anywhere near the plants...Peace and Pot
I allways veg my plants at least 6 weeks, sometimes more...then i put them under the big gun.
To keep the mother u will need as much light as u can get, but your fluoro tubes should do the job.
