Been gone a while, just read your post. I think the closest you could get with a flower would be the Chrysanthemum morifolia (morifolium), one of those. I forget, its been a year since I had plant Identification class. Anyway, Chrysanthemun needs 2-3 weeks veg cycle, long days. Then 10-12 weeks flower cycle, short days, long uninterupted night. If you can successfully grow Chrysanthemums indoors you can grow just about any Cannabis you like.
Both have the same characteristics for light requirements. If you dont give enough light they will stretch and become ugly, not marketable. If you disbud, reduce the amount of flower buds in one location you will be rewarded with full beautiful flowers. If not you will have smaller but more flowers. Same idea as topping Cannabis. Does all this sound familiar? Hope so.
Good luck.
I'd like to hear back from you, and hear how your plants are doing. I'm not usually in the gardening forum, but hit me up anyway.
Right now I have schefflera, pieris, spathiphyllum and a few other plants in a wardrobe closet under a 100w fluoro. 18 Hour light and pc fan. All are growing nicely.
