1st grow , indoors and outdoors

I was recently gifted 10 beautiful bag seeds , all but 2 sprouted . I am starting all 8 plants indoors . Notice that this was a spur of the moment decision and I have no expectations for this grow . I started them with 3 CFLs about 4 days ago and will be ordering a 300w mars hydro on Monday (actual output of ~ 150w) so between the led and the cfls I will have ~275 actual watts in my closet I plan to veg them all in my closet until they can be sexed , then I will toss the males . I plan on taking all of the plants excepted for the best looking female outside in 5 gallon buckets ( I understand that I will be putting them out later than usually recommend but I just want to see how it goes). My main question is about my indoor grow . I plan on using my closet . Currently I have my plants vegging in a fish tank surrounded on 3 sides by a car window reflector . Once I remove all the other plants it will just be the best looking plant in a 5 gallon bucket planted in kindsoil + cheap potting soil . My main concern is if the lighting and reflection I will be providing (only 3 sides covered) will be enough for a plant to properly flower ? (I know a few of these plants look suspect and will probably be tossed if things don’t improve , the plant that is almost all the way bent over has been supported with a string since the picture was taken )

 

It will be around ~6000 lumens and the area it will be covering in my closet is around 2.5ft x 1ft . Close to the minimum So I suppose I’ll give it a try
