Grow update, multiple stage plants

[Ganj]

for flowering we're using Jacks Classic 10-30-20 blossom booster, and for veg Peters 20-20-20.

We're not using CO2 right now, but growth and health don't seem to be affected, and it's a small garden. I just can't wait until we set up the blower and are able to keep the plants where we want them.

Is it ideal to keep the plants in one room from a seedling to harvest time?
