is it safe to have new seedlings under a 600 watt MH? the lamp is 36" above the tops of the seedlings. The reflector is air cooled and my temp is ~77-80F.
ok, i set the MH lamp up to 4 feet from the tops. i couldn't fit the shop lights, my cab is only 42" x 30". When should I start lowering the lamp?
I'll get some pics this afternoon. Its bag seed started in a Burpee germination tray. I just put the seeds in the wet plugs.
I plan on growing with a soil / perlite mix (i was thinking maybe 60/40) and transplanting to 4in. pots once the roots are well established and then to 3 gallon conatiners.
And yes it is a MH conversion lamp for my 600 watt digital HPS system.
The room itself is a small six foot tall box I built. For ventillation I have a twin window fan bringing in fresh air and a 500 cfm inline fan pulling hot air from the refclector.
