Help me out, Full information on my grow project

Ok here is the situation.

Light
This is the light i'm using, i probably will have to upgrade once they get bigger, don't really know how strong it is. First grow ever. Right now i simply have the light strung up about 2 inches above the plants considering its LED.

I have 3 plants already started i'll add pictures later. 2 of them are about 3-4 inchest above the dirt. One is a midget at 2 inches. They came from decent seeds from a seed bank.

Soil

They are currently in a pot of miracle grow basic soil.

I will buy nutes, but i dont really know what to get/how they are administered to the plants.

Also if i'm using nutes will a ph meter be required? I dont have one but will purchase if it is neccessary.

Grow area/ventilation problem

I want to grow it in a box or something stealthy so how many wholes should i cut in the box and will i need fans or anything or are wholes sufficient, and is there any other equipment i need?


Anything else i should buy?
Any good products for stealth growing such as cases or anything like that?
Also is my light strong enough? If not should i A. just get a different light completely, or B. (better for my budget) is there any cheap smaller lights i should just add?

Any help would be greatly appreciated. So far the community has been helpful. =]

well LED light i can't help you on that no exp

But you defiantly need a fan so the air circulates so the plant can expel toxins and the stalk gets strong so it won't topple under its own weight. A 12V pc fan wired to a 12V adapter will do the trick fine put it so it blows the air into the cupboard and at the bottom seems to be the best.

have you it lined with mylar as it will increase your crop harvest by about 20% also the bottom of your box/pot needs to have drainage like grit or stones i find bits of aero-board (cavity insulation in a house) broken up and added to the bottom does the trick as it leaves little pockets and doesn't deteriorate

well thats all the help i can give hope it helps
