coming out of the closet

hello. this will be my first time growing. my set up is in my closet i have taken several pics to show you guys. i will explain what i have on the way. so far only invested 75$ into it. and not looking to spend much more. i plan on trying to grow one plant and see how it goes.

here it is.i want to say its roughly 4 feet tall. 18 inches deep and 2-3 feet wide.this enough for one plant if so 2 plants?? it is basically the shelves that are built into my closet i have made into my grow room (or box i should say). i left a 5-6 inch gap at the top for ventilation. will this be enough or just right or too much? the shelves are movable so not a hard fix at all.

the front is made of other shelves that i stacked on top of each other to build the door. i originally had the whole thing covered in foil. doing more research i found that the plain white malmine shelves will actually work better so i ripped out all the foil. only a 2$ mistake...

here is a top view of the lights i have hanging on chains. the chains are long enough to touch the bottom of this so as the plant grows i can move them. they are 2 grow lights that have 2 6500k t5 bulbs on them 18 inches. so its a total of 4 6500k t5 bulbs. the lights also have a plastic cover over them. should i leav this on or take it off? it is really bright i hope this is enough. ha i have that attached to a 7 day timer. set to have the lights on 8am-8pm and lights off 8pm-8am so 12 on 12 off. should i run a different light time? iv read its ok to run 12/12 from young to mature plant. also i have read better to run 16/8 when young then switch to 12/12 when you want to flower.

it is not letting me load the last pic but it is just a close up of the bottom. i have a small fan inside at the bottom too. for the container i have about a 8 inch tall and 8 inch round pot with holes on the bottom for drainage. will i need a bigger pot? for the soil i got some cactus and palms soil mix. it is soil made for easy drainage. also i picked up some fish fertilizer 5-1-1. that's about it. i am open to any tips. thank you guys.

Seems like u have done your research,,,but one plant is a hard bet...better get femned seeds...

LL is right. 1 plant leaves no margin for error. I suggest 3 but keep them small. 4 weeks in veg maximum and then on to flower. Also, you need to think about ventilation. Even one plant will stink up your house. Or perhaps it doesn't matter? Your question about light cycle suggests that you have not done your homework. Start reading!
