Hey, lots of stuff to cover. From what i've read, you should have some sort of ventilation (a fan). This can be complicated further if you're planning on using CO2, but it doesn't look like it. The CFM (cubic feet per minute) of the fan depends on how big your closet is (you don't say) and on how quiet you want it to be. This brings me to the next topic, lights. You don't really have enough light to get decent bud. I would recommend getting an HID (high pres. sodium at least, maybe also a metal halide). If thats too expensive, get a few more higher wattage cfls and make sure to put all the fluorescents you have only a few inches away from the plants. You want about 40-50W of HID lights per square foot or about 2000 lumens per square foot for great bud. (I'm pretty sure thats right... )

Based on your description of the soil, it sounds like its meant for neutral pH loving plants which is perfect for now. I like a soilless mix (vermiculite, perlite, and worm castings) which drains more easily. When you transplant your plants you may want to add some perlite for better drainage.

You'll want to put mylar or some reflective material on the walls. Paint is the absolute minimum... paint the door for sure. I can't say how big your closet is, but 12 plants is a lot.

Happy growing :thumbsup:
partcleguy Reviewed by partcleguy on . NOOB CABINET Some quick questions: Can i grow without a fan? Best Reflecter for the walls? The soil says not fur use with acid loving/lime hating plants... should i change fast? Now for the essay: I guess I am a noob but i think this setup aint that bad... I got a "Arcadia" Fresf water fish lamp (14W, 15inch, (360mm)) that seems to really be bright i got a '2 feet' fluorecent tube (18Watt 230v (1150Lumen)) from "Wickes" and a 60W bulb from B&Q (yes i am in england) i got Cristal and Super Rating: 5
