You have some great looking cacti

Hello all. I've been collecting cacti and succulents for over 15 years. Currently I have about 200 succulents with most of them being cacti. The succulents are grown outside in the greenhouse during spring and summer and grow under fluorescent lights during the cold months.

I'm trying to locate an Ortho book title on cacti.
I remember the book had a back section that would give care information and flowering cycles for each individual cacti.
If anyone is able to tell me the book title, it would be greatly appreciated.

Thankyou

I use the t8's for my cacti during the winter. Some warmth from the lights/ ballasts are normal. If the ballasts are hot the the touch, your ballasts could be going bad.
