I had almost killed all 4 of mine, aphid attack, I was keeping them to wet.. I got one into a hydro bucket really late... I only have them in 2.5 gallon nursery pots, how big are you pots swilllx2p? I think mine are very close to root bound. because the one I transplanted was like a head of hair, and was growing up around the side of the container.
I'm definitely taking some clippings once I figure out if its a true bhut.. its sounding EXACTLY as you said... for sizing though..
I got mine in late June, and they are tiny compared to your plants... but about the same when I got them.
One of them looks to be ready to set flowers on this huge sideshoot, off the side of the plant.. its also seeming to grow strangely wide not tall (like a Christmas Tree, big bottom and pointed top.), I had a lot of vegatitive growth going still.
I put my largest, into a DWC bucket, and the roots are now budding around the basket, so it should be reaching for nutes soon, and grow like a weed, I hope... in the next month I can get it to set at least a few pods that I can harvest for indoor grow 2011/start of 2012 season.
