Turn your closet in to are Bud Factory



Clean IT OUT

The first thing you must do is to remove everything from your cho­sen closet and clean the floor, walls and ceiling thoroughly with a mild bleach-and-water solution and a new mop. Get a bucket of flat-white paint and roll or brush it on to cover all of the surfaces for the best reflectivity of light, and cover or fill any cracks or holes with joint compound.

You could also Bud Factory 01line the walls with special reflective foils, but I find they become more trouble than they’re worth because of the hot spots in their reflections tas well as the insects that love to hide in the space between the foil and wall. Flat-white paint reflects fine without any extra costs or issues.

When it comes to fans and electronics, it’s best to run a tight ship. Rubber and felt gaskets seal Leaks and buffer the sounds cre­ated by vibrating fans. Also, there’s no harm in double-bagging your closet grow with a tent, which tends to trap moisture and de­flect heat better than a plain closet, and also provides one more barrier between your skunky secret and a nosy neighbor’s nostrils.

Because of the high premium on real estate in your closet, run as much of the power and water controls as you can outside the tight space. Ballasts as well as air and water pumps give off heat and are not best suited to the humid environment your plants enjoy. As a general rule, any space you save by rerouting equipment will be converted into harvest I old at the end of the grow cycle.

separate chambers

If you really want to get the most out of your small space, you need to separate it into two smaller areas: one for vegetative growth, mother plants and cloning, and the other for flowering plants only. The best way to accom­plish this is with a shelf placed about one-third of the closet’s height from the top. The smaller upper area will be your vegetative space, and the larger, lower two-thirds becomes your flowering area.

The vegetative area must be completely light-tight, because even a glimmer that seeps into the flowering area when it’s supposed to be dark will cause your plants to revert to vegetative growth or freak out and turn into hermaphrodites. These Leaks can be avoided by sealing

the vegetative area completely with a dark plastic liner.

Your vegetative area should be lit with fluorescent Lighting, such as compact fluorescents or short T5 tubes, which will provide enough light to keep mother plants alive, root cuttings and keep vegging plants thriving early on. With these vegging Lights on, get inside your flowering area and make sure no Light is leaking into it. In other words, it should be completely pitch black in your budding space—and if it’s not, make it so before embarking on your closet grow.

High temperatures are your biggest hurdle when grow­ing in enclosed areas such as a closet or small grow tent. Ventilation is essential in smaller spaces, as the available fresh air becomes spent quite quickly. Leaves suck in CO2 and release oxygen in order to perform their photosynthesis functions, which means that re­plenishing the 002 in your grow space is essential to keep your plants thriving. This requires both an intake and exhaust fan, as well as a small oscillating one in­side your grow space to keep the leaves moving.

It may look odd to have tubing running from your closet, and if you’re growing in an apartment where that might pose a problem, look into cutting a hole in the wall or ceiling inside your closet and running your ex­haust fan through a charcoal filter and into that gap. The force of the exhaust will pull enough fresh air through the cracks in your door and create negative pressure, which prevents odors from seeping out and endangering your safety.

You can also purchase a CO2 tank and regulator or a generator, although both have their drawbacks: The tanks need to be filled regularly, and generators create unnecessary heat in your tiny space.
