Neat lookin girl you got there! I would throw in at least a 100w-150w hps if you can find one there usually pretty cheap less than $100 as far as yield your lookin at a few grams possibly.
dont even bother..... this person seems to hate taking advice. And asks the same questions over and over and over. Im surprised they got this far, but i think they still wont finish a grow. I've come to this conclusion after reading almost everything they've posted, trying to decide whether to help or not.. The first few threads set the tone....
This person had a 6 week old plant on its 3rd-4th node, and asked for help.... by saying they've grown with their 40w cfl setup before and had no problems so it "couldn't be" what everyone was saying (fan, more light, better soil, etc). It was.
Then when the plant hit flower op admitted to never growing a flowering cannabis plant.
I thought op had grown in that setup "fine"?
Someone got really fed up trying to help this person and basically did what i am now doing, warning helpful/knowledgeable people not to waste their keystrokes. Someone else out there (who listens instead of acting like a stubborn ass on a hot day) is much more deserving of help.
Ill give my two cents, but i really hope Covered Society listens and stops posting the same lighting/yield/will it be fine questions day after day. His questions were all answered more than once in his first three threads, yet he continues on.
The sun will help, although constantly switching spectrum/temp/humidity will likely slow growth to about the same speed.
As for yield, you seem like a .2 gpw cfl kinda person so you should get ~5-8 grams if it finishes right.
As for whether these lights are enough to flower, you don't seem to care. General consensus is no, or only if you focus on the 2 main buds at the top and remove everything else. The general answer is at the minimum pick up 2 socket splitters and 2 more 20w 5000-6500k bulbs.also pick up an emergency blanket. A successful cfl grow using 80w-150w of cfl can grow easily grow 25-80 grams. If you add 2 20w (80w grow) and yield .3 gpw, you would yield about 30 grams, ~1 oz.
But again, you seem utterly against doing the baseline standard. You insist on less... So I doubt you'll get the required/recommended lighting. I hope one day you learn 6 23w cfls is not "overboard." Its very baseline minimum. Just read some damn cfl grow tutorials. They'll all recommend 80+ watts per plant,and often are recommending 4 40w bulbs. With that 120w, .33 gpw gives an even 40 grams. And obviously, if you have any skill and get say .5 gpw, you'll have 60g.
Tbh, I think you should just screw trying indoors and try guerilla growing.
edit: also, if you had a mh hps setup, about 2 days from now would be optimal for reveg, as you'll get a monster cropping effect and have the plant go from 2 tops, to 20...
