Aus - is this your first grow?

In my opinion - I think you'd be better off just taking 10 minutes every 2-4 days and just water your plant.

You being in the growroom/grow area alone, will also give them a little rush of fresh c02.

If you're looking for a hydro setup (which it looks from your picture), I would check out some of the grows/setups in the hydro forum to make your questions a bit more specific

Good idea, brotha.
