How can I help my cactus?
I've had this cactus for a little while, he's been through a few moves with me now. I'm not sure what type of cactus he is.
He's started to get kind of tall and I'm a bit worried that bulb-like part at the top may break off. Is there something I should do for him? Is the top part breaking off something I should be worried about? Is it a sign something is wrong that he's growing like this?
I'd appreciate any advice! He's currently under a grow light and gets water sporadically, if that helps at all.
