I think its a great question that needs to be answered. Everyones results will be different, but if the numbers are out there it could be very helpful.

These are rough estimates, but here it goes.

Xenia elongata: 500 watts of light, 32 sq feet of growing area = 200-300 stalks per week harvest. 16 sq ft used for mother colonies, 8 for settling and attatching and 8 sq ft for growout.

Zoanthids: 2000 watts of light, 164 sq ft of growing area= 600-800 frags harvested per month. 100 sq ft for mother colonies, 16 sq ft fits 800 frags. 4, 16 sq ft tanks used to allow 4 months of growout. (These numbers are from the old facility and will be changed in the new one. too much space was used holding mother colonies. New fragging techniques allow much less space in mother colony tanks)

Kenya tree: 375 watts, 24 sq ft= 60-100 frags per month harvest. 16 sq ft for mother colonies and 8 sq feet for growout. Need 2-3 months to achieve sellable size.

Anthellia: 375 watts, 24 sq ft= 60-100 frags per month. 16 sq ft for mother colonies and 8 sq feet for growout. Need 2-3 months to achieve sellable size.

Toadstools: 375 watts, 24 sq ft= 60-100 frags per month. 16 sq ft for mother colonies and 8 sq feet for growout. Need 2-3 months to achieve sellable size.

colt corals: 250 watts, 16 sq ft=40-60 frags per month. 10 sq ft for mothers and 6 for frags. 2-3 month growout time.

Acanthastrea: 500 watts, 32 sq ft= 40-60 frags per month.

16 ft for mothers and 16 for growout. 4-6 month cycle of harvest. (numbers are estimated since brood stock has not been fully developed yet)

fast growing sps species(monti cap, monti digi, elkhorn, etc): 500 watts, 32 sq ft, 16 for mothers and 16 for frags. harvest depends on size desired. 1"-2" frags =2-4 month cycle, larger can exceed 6 months. Appx harvest for this sq footage is 40-100 frags per month.
