2 4ft t8's or 4 4ft t8's for mums?

I am getting 3 mini mums, about 18-20 inches tall that I will need to produce about 16 clones every two weeks (total, not per plant). I just bought a fixture with with two 32 watt 6500k t8 bulbs. Do I need to get another one for a total of four bulbs or should the two be ok.

this is my first "mom" experience....thank you!!!!

no one? need a little newb help...........

how big is the fixture 2 ft or 4 ft? how big are the pots for the mothers?

I'd just remind you that fluro fixtures have a foot-print that is pretty much directly down... not a lot of spreading out...

So make sure whatever you rig up... they can fit "under" the lights and get the light they need...

Go 4 bulbs or 4 weeks into flowering you'll be buying one. I grow 3 rows of 2 plants under 8 4ft T5's and I top my plants, they still fall outside the foot-print of my lights I constantly rotate them.

3 plants spaced apart will need 4 bulbs unless you are growing single cola plants!!
