I am, and I have them under a grow light but their leaves have been turning black. I think I'm just frying it with the direct sun that comes through the window, but I've blocked that so hopefully they turn around.
I'm not sure what else could be turning the leaves that black color before they even mature, but if you had any tips that'd be great. Hopefully closing the blinds on that window are all I need to do.
They can take the sun, I'd look at your water. Distilled or reverse osmosis water only, TDS should be below 50. You can get a cheap TDS meter for under $20 if you're not sure.
