cfls will not always generate low yield if you have them positioned right and enough of them so no shadow spots, you could say lol if your on a budget cfls work great good luck bud
for 1 plant yea its fine just get the 55 watters from walmart or somewere their like 10 bucks here. during flowering mke sure to have soft white bulbs. the good thing with cfls is they wont burn your plant unless direct contact to the plant.
yea early morning sorry just read your description n when the top seems a bit crusty water her usualy 1 every 2-3 days but water unit you have some runoff
