If it's just for one seed. 23 watt 6500k bulb will do. Just keep it 3 to 4 inches above the seed when it pops out. If you don't have a 6500k bulb 5000k will do. Best of luck with your grow.

How much should i water in the beggining?
I'm growing Green Gelato Auto from RQS, this is the first day and it's hot outside (31ºC). I don't know if I'm watering too much or too little. I spray with water 10 times but it dries up after a few hours. Should I water it more?

Is this Shell membrane crucial to life? Will this bag-seed Seedling survive?
Will it survive? The seed was pried open with saliva and pruners once it broke soil. I see some brown (what I suspect to be) membrane that maybe needed to stay with the cotyledon.

Help with seedlings falling over and dying :/
Could someone please look at my two seedlings and tell my why they are falling over? I planted four golden goat seeds, which all sprouted. However, two have already completely fallen over and died. The one with the makeshift supports was completely flat this morning. Thanks
