It depends on what u want to get out of the grow and what strain you are growing. Some have longer cycles.
From what I'm learning with my 1st cfl grow, the more lumens the better but u dont have to spend a ton of money for 1 or 2 plants. Patience is key, too. The longer the veg. the bigger the plants. The same with the light. THE MORE, THE MERRIER!!!!
I started the first 6 weeks vegging with (2) 100 w. daylight with aluminum reflectors that increase by 50% for 2 ladies. I have since added a couple more cuz I will probly be flowering in a couple weeks. GET THE REFLECTORS!!! They are a huge, cheap, effective asset.
I have an indica strain, so my total time will be like 60-80 days more once I change they're light to 12/12...I believe and a few weeks longer for sativa strains. heres my cfl babies!! 6 and 7 weeks from germ.
GOOD LUCK and keep updated!
