Several months ago my girlfriend bought a small cactus at our local Home Depot. It came in a very small pot and has a large, bulbous red head with little yellow "things" sprouting out all over the top (shows you how much I know about cacti). All was going well for a few months and the little guy grew and flowered a few times. Then a few weeks ago it seemed to get sick. The green stem is now a nasty brownish color, but the head remains red and yellow. She asked my to try to save him and I naturally said yes. The thing is (as I mentioned earlier) I know NOTHING about growing these plants. Right now it's sitting in one of my grow chambers under 80 watts of light.
Can someone please give me some tips on how I can go about saving this little guy? I have some diluted fertilizer that I use on my CPs...can I use it on the cactus? How often should it be watered? Is 80 watts of light suitable? Can this plant even be saved? I really need to read up on cacti...
