Hey guys this is my first grow. The strain is 8ball kush and it is 12 days from seed. The other in the pic is 3 days from seed. It is an afghan milk strain. The soil is FFOF mixed with perlite. The mix is about 60:40 FFOFerlite. The first seed I didn't put a plastic cover over, the second I did and it looks like its starting off a little faster. How long do you keep the cover on? Also I read that the seeds wont need nutrients for about 2-3 weeks in FFOF, is it about time to start giving my 1st one nutes?
