I am a beginner grower. and have some questions about my grow room setup. i have ordered some jock horror seeds from nirvana and on step 6 of 7. about the grow room i have a closet where i plan on growing but it has no door. any suggestions about building a door? it is 27 and a half inch by 76 and a half inch. and i need help with lighting, the floor is 42 and a half inch by 76 and a half inch. will a 200 watt mh or hps work good for six plants? also i am going to seal the walls and floor with mylar, how many feet of mylar do i need?

yep, don't build one buy one. They make prehung interior doors 24" wide. Gives you enough clearance around to install it. You can cut it for height. If its just veneer you will have to put something in the bottom if you do have to cut it off. They stabilize them with cardboard at the bottom, only goes up a couple inches. Around $40.00 on sale at the big box stores.

it is 27 and a half inch by 76 and a half inch. and i need help with lighting, the floor is 42 and a half inch by 76 and a half inch. will a 200 watt mh or hps work good for six plants?
It will do ok not great. I always recommend t-5's to closet growers. They produce less heat and can produce as much light as a 600watt hid light, bulbs can be mixed, no separete ballast, saves a foot of height etc.

also i am going to seal the walls and floor with mylar, how many feet of mylar do i need?
Bad idea. Mylar will not last on the floor and isn't necessary. Use some regular visqueen for the floor. Doesn't really matter how much you need for that space. the smallest size I've seen for sale is a 25' by 42" roll, plenty for what you need.
I would suggest covering the walls and making a light curtain for across the door opening using panda plastic first. Only put the mylar where the light is going to hit it and reflect it back to the plants.
In order to tell exactly how much you need add up the dimensions of your walls including the height. VV

you can use a 400 watt hid light. You will want one that is air cooled because it will produce a lot of heat. The t-5's are florescent lights. They come in 2' and 4' sizes. You can get them with as many as 8 bulbs, unlike the hid light which has one bulb. With the hid you would need a switchable ballast if you wanted to use both the mh (metal Halide) and the hps (high pressure sodium), or two separete ballasts. With the t-5, all of the spectrums of bulbs fit the fixture, no seperate ballast is needed. Because you are spreading the heat over a two foot or four foot fixture you have less heat to deal with, you would not need to air cool the light and it will take up a foot less height. The ballasts are in the fixture instead of being seperete. The 4'- 8 tube fixture uses 440 watts of electricity and will put out light equivalent to a 600 watt hid. By the time you add the cost of running a fan to cool the 400 watt hid, the electric costs will be about the same, but you will have more usable light. I don't own stock in any light company. This is just scientific advancement in light fixtures. Folk look at the hid's and the are bright so they assume its more light and it maybe. Problem is you have a lot of heat and can't get them as close to the plants. The light is lost as far as the plants are concerned.
I started with 3-400 watt hid's, still have one in use which I will replace with a t-5 fixture. If I were growing in a closet, I'm not, I would get the t-5's not the hid's. VV

but will the t-5's produce an equivalent amount of bud? From a lot of the posts here it seems like people go with the HIDs for yield...
