Hi 420, new grower here.
I just germinated 10 white widow seeds. They all cracked (10/10 props to Crop King) and grew taproots, and once the taproots were about 1/2" long, I planted them into solo cups. It's a coco coir / perlite medium. Moistened with pH'd water. I put the cups under about 90W of CFLs immediately. Nothing has grown and broken through the surface yet.
First of all, I'm wondering if it was a mistake to leave the cups under my CFLs constantly. I understand that seeds want darkness, but is 1/2 inch of coco medium enough to protect the seeds from harmful light? The bulbs are about 4" - 6" away. Should I have waited for them to break through the surface before exposing them to light? I think they were briefly exposed during the planting, as well.
My second question is in regards to my new Mars II 900 LED grow light. I'm really excited to start using it, but I'm worried that it's too strong to use on freshly sprouted seedlings. I'm also worried that if I start them under CFLs, that they'll have a hard time making the switch to the LED.
Hoping that somebody has some experience with this particular LED or growing with LEDs in general. I've done so much reading and research about growing in general lately, and there seems to be so much conflicting information about simple things like light distance. Need someone with experience to reassure me that I can do this LED grow!
Thanks for your time.
