My 1st growing cabinet. Mistakes???

This is my first post. I would like to give you the general plans for my first grow cabinet and would appreciate any advice.
I have two kitchen corner cabinets 22" x 22" x 28" high. Each cabinet will contain an adjustable top panel of 3 compact fluros: 100 watt, 1600 lumens each. I'm going to line the cabinets with aluminum flashing that I have laying around.
My plan is to grow 4 plants in 2 gal containers using 1 cabinet for veg. using 6500 kelvin lights for 1 month, 24/0 (hopefully 12-15" plants). Then transferring them to the other cabinet using 3000 kelvin lights for 2 months, 12/12.
Any problems??
How much additional growth should I expect during the flower cycle?
This forum is awesome. Sometimes the internet still amazes me!!

your plant will almlost if not double in size. depends on the enivorment control, nutes, etc.

Welcome to RIU! Glad you decided to join us. Like damon420 said they should at least double in size before they finish. The only thing I would recomend is using flat off white paint insted of the aluminium. Its right behind Mylar for light diffusion. Aluminium causes hot spots and is at the bottom of the list above black paint for diffusing the light. Good luck with your grow Bro. Peace Out!

with only 28 inches of height , you will definately run into height problems...
your plant in a 2 gallon pot will easily outgrow that...

a suggestion ... either buy some good auto dwarfs (an autoflowering strain... autoflowers and stays short in height) grow sog. or flower at 6-8" your going to have to keep those fluros very close to the plants..

Thanks for the warm welcome and the tips. I will be utilizing them all. My seeds came TODAY. So, let the games begin! I'm going to treat this ride like my golf swing:

Relax
Go slow
