Just wanted to post a few pics to see if anyone can dish out some valuable advice. I plucked a seed from a mandarin I bought at WalMart. Planted it to satisfy a curiosity but now I really like the little plant. First time growing anything so be gentle. With a non-existent sun and cold weather I have it inside under some CFL bulbs. I think I need to upgrade to a bigger lighting solution as the leaves seem to be curling toward the lights. How are the LED lighting systems? I also discovered the roots are crawling out from the drain holes at the bottom of the pot. Does that mean it's time for a bigger pot? Current pot is 8" diameter and 7" tall. Lastly what can be done with that curled stem?
