im not stateing something that hasnt already been said but here is my 2 cents..
i plant my seeds in peet pelets and put them in a humidity dome. u can use the cheepest most efficent piece of shit light u can find to put on top...it dont matter. put them in the bathroom on the sink and leave the light/fan on will work just fine as well. 3-4 days later the seed will sprout and start growing. i leave my little girls in the dome till they reach the top of the plastic dome and then transplant. 14-20 days and they should be at the top or close to. spray the seedlings with good ph water 2-3 times a day to ensure they stay humid. this is not foiler feeding!! because it is a seed and not a clone, it has a root that it feeds through and not the leaves. with a seed..u are misting to add humidity, not keeping the plant alive. with clones its a little different, but not much. by leaving them in the dome as long as possible u will get the max growth. ive done tons of side by side comparisons and when u leave them in the dome till they reach the top, its hands down twice as quick as pulling them out ANY sooner. once they reach the top, i gaurentee u can plant them outside. i live in east oregon and our late spring/simmer temps here are 90-105f and if u plant a small seedling out in those temps...they will die as quick as u can plant them unless the plant has enough veggatation on leaves to cool itself down.
