See here we go again, i grow nothing but autoflowers for 8 years on top of growing outdoors for 40, autos are touchy, bitchy, and simple to burn, they lie about the yield and if grown outdoors you get even less, first off you need a nice cool mix, second make shure your seedstock is good, i generally grow sweet, mdanzig, Buddha, and methesto, these are quality auto seeds that seem to give me the least amount of problems, ok your on amozon looking at cheap lights, I have a 4×4 tent and bought a viperspectra 600w reflector series, this is a good veg light for under $200, I never tried to flower a plant with it beacuse I own a
California light works bloom booster $400, this set up works great for autos, when my autoflowers are done with there growth spurt is over around day 35 I then run both cycles veg and bloom this will help my flower grow till about day 50 when I flush out the food and add bloom nutrients, I then put my autoflowers under my bloom booster till they finish between day 65 and 80 depending on size of plant, now if you have a couple grand I would suggest checking out black dog great lights, or you can do what I did and buy a cheap light to get started, good seeds, use
smart pots, I use botanacare pro grow for food after day 21, as for bloom I use either botanacare pro bloom soil formula or
atami bloombastic, for medium I use ffoc
happy frog is a hot mix never had trouble growing with
ffof, in my opinion autoflowers are more difficult to grow beacuse there time oriented with a limited life span, but I do ok, if you need help don't hesitate to ask.
