I am a newbie and i have 16 ssedlings in a closet. 8 at 4 weeks and 8 at 3 weeks. No specific ventalation yet. I have closet doors open 4-8 hrs per day.
1 4 bulb 4 foot 40 watt Flo +160 watts for 24 hrs day at 6-12 inches distance.
Organic potting soil. Water every othe day. Mist every other day and i skip one day a week. I put a fan on them on medium every night for several minutes and it really seems to have helped strenghten the stems i no linger have to support them. Planning to start feeding and changing to a 20/4 cycle. All seems fine. But I have one plant that has leaf shoots comming out at leaf stem base starting with the second set. It allready has 7 leaf sets and most have 7 points instead of 5. The largest leaves are over 4 inches across. This seems very advanced at 3 weeks.
Any suggestions or hints will be helpful
