Need Some Help Designing Closet Grow Room

Okay I need some help designing my Closet for a larger grow that I'm going to do.

Right now I have 2 clones from a plant that was flowering so i reverted them back to vdeg and they are vegging under CFL's. These 2 plants are going to be my mother plants. My plan is to take 25 cuttings and root them and throw them in the flower closet I'm building. The Closet is built but not ready for grow. I may be doing a SOG grow but not sure yet. Anyway here are the Specifics.

The Grow Room Closet Dimensions are:

Length = 5.88 ft.
Width/Depth = 2.17 ft.
Height = 7.9 ft.


I have decided on either using a 600 or 1000Watt HPS with a reflector with a 6" vent opening.

I need to know the best way add an intake to the room and an exhaust. Also why size containers I will need for the plants to finish with good yields being thrown directly into flowering after they root.

Is this enough space for 25 plants?

my intake should drawing in air from outside? Keep in mind it is winter here. and Should the exhaust air be going outside?


Some simple questions but I want to have everything ready. I have probably a month or two before I take the cuttings and I'll have to buy this stuff in the mean time and get it together and test the area for temps/humidity etc.

Also open to suggestions on what kind of ventilation fans to use and size CFM they move.


Any help would be greatly appreciated. Thanks in advance.

Ok first of all regardless weather or not its winter you are going to want an intake and an outtake sucking the heat of the back of the hps because your gonna fry your plants in 100 + degrees without both. Second you are not going to be able to do 25 plants and an area that small unless you are flowering them at 4 inches. Go for like10 or 12 medium size plants grow them out to about a foot then flower them. If you dont overcrowd them they will reward you. i would do a max of 15 plants in a space that small. put a pair of pantyhose over your intake to keep bugs out of your grow. have your nutrient line ready to go and stick to the same brand. ppms tend to go nicely together when using the same line anything else just let me know

Okay yeah I wasn't saying it was winter so it would stay cooler in grow area. Just wondering if the intaje/exhaust if both or either need to bring in outside air or take air outside.

15 plants doesn't sound bad.

I kinda need a step by step setup for the intake and exhaust exactly what to use and what to do with it. Pantyhose idea sounds good. Do I need an exhaust besides the ducting I'm going to run the the light to suck the heat out. I have Fox Farm nutrients for veg and flower I have used them before with success. This is not my first grow but will be my first grow with HID system. This room will always be on 12/12 lighting and will be refilled with 15 new clones after each harvest. Do you know what size plant containers I should use. I have decided to use square containers to use the space better.

I'm just looking to get the best ventilation I want to keep temps between 70-78 degrees I know HID's put off a lot of heat but like I said I'm unsure how to do the intake/exhaust with the light and for the room and want to get this right on first go as it will be a continuous cycle.

Thanks blink1821984 for your post.
