I put together a 3-room perpetual grow and have a couple suggestions.
I think that choosing smaller 2-gallon pots was smart. Bigger pots mean there is a lot more variability in the size of your grow.
It is much easier to control plant height with the smaller pots, and, varying plant height will be one of your major headaches.
Stick with the 2-gallon pots.
I see you are planning on using monthly intervals; 6 clones this month, 6 clones next month, etc. Unless you are going to be growing
clones ONLY from the 2 original mothers this will be tough, again, different strains and varieties produce rooted clones at varying rates.
I would suggest the schedule I eventually adopted -- do every thing by the week, not the month. I take 2 clones a week, root them in the dome room,
veg them at 400W in the veg room then move them into my 1000W flowering room. I count on one plant per week finishing. I root 2, pick the healthiest
and scrap the other one. My veg room is actually a closet in real life, maybe 4' x 6'. So there is room for 5-6 plants to veg at a time. By using a weekly
schedule I don't have to worry about clogging up my veg room. I can fit 5-6 plants that are all a week apart in the veg room where I could never fit more
than 3 larger plants. A weekly schedule gives you a lot more flexibility bro.
