Pretty much says it all. the trick for indoor growers is to get basically, a very high level of light, but without the attendant heat and dryness which lights bring. Even flouros can heat up a space too much.
Healthy strong quick growing plants, also a very pest resistant, and if problems occur, they can often grow the problems.
Sun right now in in the Northern Hemisphere is almost perfect for outdoor growing, with shade screen or shady spots. Full sun is still abit much, but my entire patch is getting 1 hour at midday, which last year hurt it, but this things are "different".....
Peoples take those plants out for a walk around the block.

I have some stick cuttings in dirt, no roots..... which I have doing this too, rather then letting them rest in the shade, been putting them in FULL MIDDAY SUN for 5 minutes at a day.....man its like they are squirming green!!!!
I am very tempted to pull them up and look and see if roots are forming....(no no don't do it...OK I won't)....as they stems are so fat, and little nubbins of nodes are swelling.......
I have maybe 4-6 spikes started, about 2 inches long, I'll post them in an appropriate thread. Tallest plants first, for whatever reason...and the ones in the most sun....shady section is lagging....
