Nah. It's simpler to shorten their exposure. Or raise the fixture so the haworthias are farther away. Adros need more light than haworthias to stay compact.

Do you have room to put the Haworthias out of the 'hot spot' of the lights? That's what I do in my kitchen and it's working well, but my collection is sparse.

Maybe use a shade cloth on part of the rack for the tender plants. Or dedicate one shelf to them and raise the light.

Yup, put them on the edges where there is less light. Two T8 or T12 isn't so crazy and many Haworthia may be fine under that depending on your light distance.

I spend a fair amount of time shuffling plants around all year long under lights to find the perfect place for each.

For shade you can use one or two layers of black window screen.

Im not using 2 T8s, I am using 4! I did not know I was not using the old flourescent bulbs. Is that too much light for anything? Im thinking that some like it and some dont. I have moved those who want less to the outside, and taken off the mylar reflectors off the sides. Maybe I don't want more light.

I don't think 4x T8 bulbs is too much for most succulents (maybe for some haws? - I would go by what Pagan, Howard, Kevin do - they grow many 'exotic' haws. So do some other ppl - I can't think of all names:) . I don't use T12 anymore. Just got first T5HO recently.

The problem with too much light isn't generally the light itself but the heat. I don't think that would be too much light, even for Haws, so long as you harden them off to the increased light. I have a gasteraloe that would turn a dark purple green in the southern window but it didn't burn because it was accustomed to that spot. I've moved it to a western window and it's a boring green now.
