Using FIM, Suppercropping, and scrog together ok?

That guy again ya'll. I had a few advanced questions. So were better to go? I recently went with a cheep co2 method. (6 cups sugar, 1 gallon water, 4 tablespoons active yeast.) Will this release enough co2 for my 8 plants?

Also At harvest I intend on this grow to try everything at once. I intended on scroging the plants and prunning them thill I get a nice canopy, then using the FIM technique I read about on here. Anyone know if that is a good idea to do all at once? Or would that be to much on the plants? If they can't handle it I was gonna do the FIM technique. But another question; Can you do it to all the bud sites or just a few?

Please help anyone...

Well, not much help yet but I got time. My girls are only an inch and a half tall. Anybody tried any of these techniques have good results? Are they worth doing? Help please!
