The watering aspect should be one of your main concerns. Watering when they need it is key. If the dirt looks dry and the cups feel light then its time to water. The plant looks great. The first 36-48 hrs of germ is key. Try getting yourself some flexiplugs, tray of 50 slots, Water collection base and a clear plastic humid dome. Works for me every time and one 50 plug setup should run you about 20 bucks. The dome has 3 vents you can crack slowly around day 7 to get them used to the oxygen. This also promotes a strong straight stock. Mist the dome occasionaly and leave a VERY small amount of water in the base to promote good humidity. as close to 90% as you can. Once they have a mean root comming out the bottom with smaller "hair-like" roots branching off move them to 16oz Styrefoam cups with small holes poked in the base to allow excess water to drain.. I start from seeds every time. As for the light, IMO I start em' off on 24's from the rip. It gives the beginning shoots something to work towards. . The 18/6 works well later if you so choose. T8's work great, and their pretty cheap. After you water you can always mist the smaller plants with a SMALL amount of water from a sprayer to simulate rain. AGAIN this is all just my methods and preference. I just dont want my first post on here to be flammed over n over. hope this helps. let me know. good luck bro
