New member, NEW GROWER , Need HELP!,

i have had the hardest times rooting seeds in rockwool i always use a paper towel and after they sprout then straight into hydraton pellets, its a salt build up on your pellets. won't hurt anything , are you using well water? i always use regular peroxide for my plants and add 2 tbl spoon full of it with every refill of my res or adding nutes.. i have roots that smell and TASTE LIKE A FRESH SALAD. YES I SAID TASTE. i take a lil sprig that falls off and i will taste it for freshness unless its mushy and nasty.. taste like a bean sprout.. hmmmm refer salad.. how would that taste??? lol

can anyone tell me if this is good for now? its my bootleg humidity domes, and the second pic is just to show u how far from the lights they are, but my questions is this set up ok?

that will work put plastic wrap over the tops and spray the insides with water

Okay, so where I'm at today is i have them in the box just the rockwool with my bootleg humidity domes over them i recently put a clock/thermometer in my box an i saw the temp was at like around 88 so i opened the box up an took out my 2x18w cfls and put a lil fan in front to bring down the temp, now its at 80-82 with the door close an only 1 42w cfl on them i also lower them from the lights, is this temp okay for my seedlings?
