Hello BKSkillz.Since no one eles is posting i throw my 2cents in.Ok first things first i am assuming that your 100watts cfl's are truely only 23watts of true fluorescent watts.That will just not do for so many plants.Your gonna need about 6 of those for about 2 plants (Also keep in mind i say 6 because it's close to 2200lumens psf.so 2200lumens psf= good lighting).Also the foil need's to go it focuses light to one spot and burnes it and really doesnt reflect much compared to white paint or mylar or the saftey blankets.As for ventalation ''Redeyed'' is right those small pc fans would work great in your situation.Also is there any air movement in your tub.a good fan will make your stalks thick and then can suport it self.For now thats all i see is wrong that is keeping you back from a perfect grow.Also lay of nuts.
