I was thinking about using CFLs on the seedlings and then switching to HPS for vegetative growth. How many watts would one seedling need and how long should I wait until switching to HPS?
Yeah, just get a 25 watt CFl (6500K), maybe 2 if you are ambitious. Keep it within a few inches so she won't stretch towards the bulb. Good Luck!
That really depends on the yield you're trying to achieve, and the characteristics of your particular strain of herb. 4-5 weeks of veg. for a clone should be good. If you're growing from seed, keep the plant vegetating until you have several internode (branches, not fan leaves) before you switch to flowering. 5 weeks of vegetative growth
I bought three of the undercabinet lights from walmart.I then switched the bulbs to 2 grow and 1 daylight.The new bulbs are a hair bigger but fit.This setup is rather cheap but works great for my propogation..You could prolly get away with just one lamp at first tho.GL
