I too have become hopelessly enthralled with them. I just bought a brand new LED growlight set up for them, hopefully they'll like it, too!

The most important thing, i've learned through the wonderful members here, is to ensure that there is a noticeable drop in night-time temp. I've been growing them for eight months with little success, but after opening the window that they grow on at night (after a members suggestion), i've got roots and leaves going out all over the place!
