This how i keep my cephs, id love to cover this entire shelf, with them.
t-5 4 bulbs, humidity 40 to 60 percent, though I dont keep that close an eye on the humidity,
day temps 75 to 82 F , down to 69 to 70 F at night.
Ive had one of them drop the lids totally, and to my horror it was almost bone dry , it took a week but i got it back in shape and its growing like a weed ( as cephs grow LOL), mine really drink lots of water, I think its due to the close proximity to the heat and intense lights, and fans. I do mist my pitchers, but am very careful not to let them stay wet for more than an hour or so, the fans and lights dry them quickly.
from what ive read there others that are growing in almost the opposite extreme of my conditions, dryer, less humidity,lower light levels etc. so are cephs really that picky?
