As long as you understand one thing, it all makes sense. The one thing is this, whether you wrap your seed in a damp paper towel and put it in a small dish, covered by Saran Wrap, and place it on something WARM(like a cable box which is what I do), OR just stick it a 1/2 inch down in some moist soil and put a lamp over it, what is eventually gonna make it sprout is the warmth of either the cable box or the light. It's NOT the light that makes it sprout(or not sprout), it's the warmth from the light(or the cable box). So what I'm sayin' is that it doesn't matter if it's dark or light, just warm and moist.This is so inconsistant. So many people swear by germing in the dark. Which is it?!?! Does it matter if your using rockwool as a medium?
You can either keep the lights on 24/7 in veg, or keep them on 18 hours and off for six. Loads of ppl do both. I like the 18/6 times for a couple of reasons. One, the main goal for growing, FOR ME ANYWAY, is to duplicate "Mother Nature". Plants have a dark period in nature. Two, saves $$ on the electric bill. I don't know about anyone else but I don't just have a light on in veg. There's the light, the humidifier and the fan. I "Veg" all my plants under CFL's(see photo). That one was vegged for 6-7 weeks. So, I like to veg under CFL's. I do AGREE 100% with indianaman as far as flowering goes, HPS is the way to go.leave the lights on 24-0 until they're like 45 days old. if they haven't pre flowered switch the light to 12-12 to induce flowering. i find that 24-0 makes your plants crunk! hate cfl tho HPS all the way.
