Ok, this is my first grow, is it alright to use a 400W HPS light to veg my plants, im thinkin about growin 4 - 5 so that im hopefully left with 2-3 females.
Or should i use CFls, if so how many CFL lights will i need, would say 5, 20W cool white CFLs be fine for vegging?
As well when should i switch to my HPS light
Cheers
