There is not enough detail for me to see if it would work or not. I can assume it would be fine for growing a few plants very small. To do a cycle grow you would need to have more then one unit. All the plants grown in unit A have the same light, same nutrients and should be on the same grow cycle. This plants nutrient requirements change quickly with each cycle it grows through. So to have a perpetual crop you need to grow from clones so you know the sex and you need at least 2 places separate from each other so when one is in 12/12 flower the other one is in Veg 18/6 light cycle.

So what you were thinking was correct in the first place.
