Right on!
That small veg cab limits my options, but it is EXACTLY what I had planned.
The two big advantages to running a single strain is that: 1) they should all finish about the same height (which is not important to me, currently, but good for SOG, SCROG, or other height limitations); and 2) they should all finish about the same time.
That second point is important to me since I'm going to be taking clones a few weeks before the plants in the flower tent finish so I can limit the time the clones spend in that small veg cabinet. If one of the strains takes an extra 30 days to finish, the waiting clones, again, will outgrow the cab.
I'll likely run multiple strains on the first round, just to get another harvest in ASAP. From there, it will be only one or two strains at-a-time, assuming I have two strains that finish about the same time.
