that just came in from the garden outside? Did you just fondle your spider mite infested split leaf philodendron in the living room? Avoid such problems by washing your hands, and changing shirt, pants and shoes before entering an indoor garden.Once a crop has been grown in a potting soil or soilless mix, throw it out. Some growers brag about using the same old potting soil over and over. Unknowingly this savings is repaid with a diminished harvest. Used soil may harbor harmful pests and diseases that have developed immunity to sprays. Starting a new crop in new potting soil will cost more up front, but will eliminate many potential problems. Used soil makes excellent outdoor garden soil. Warning!Growers in Eugene, Oregon tossed their outdoor soil out in the back yard for many years. The soil was about 50 percent white perlite and had a distinctive color. This oversight eventually got the growers arrested.Once potting soil is used, it loses much of the “fluff” in the texture. Compaction becomes a problem. Roots penetrate compacted soil slowly and there is little room for oxygen, which restricts nutrient uptake. Used potting soil is depleted of nutrients. A plant with a slow start is a perfect target for disease and worst of all, it will yield less!Companion planting helps discourage insects outdoors. Indoors pests have nowhere to go and companion planting was not viable in the grow rooms that I have visited.Super Size Secret:Always plant about 10 percent more plants than you plan to harvest. If one in 10 plants can become infected or sickly, remove them from the garden. Removing entire plants is the easiest way to isolate and control most pest and disease problems.Plant insect and fungus resistant strains of marijuana. If buying seeds from one of the many seed companies, always check for disease resistance. In general cannabis indica is the most resistant to pests, and sativa’s more resistant to fungal attacks. When choosing mother plants, inspect them regularly for pest and disease resistance. I am always amaze

when I see infested plants alongside healthy ones in the same garden.Keep plants healthy and growing fast at all times. Disease attacks sickly plants first. Strong plants tend to grow faster than pests and diseases can spread.Forced air circulation makes life miserable for pests and diseases. Pests hate wind. Holding on to plants is difficult and flight paths are haphazard. Fungal spores have little time to settle in a breeze and grow poorly on wind-dried soil, stems and leaves.Super Size Secret:Preventing pests and diseases is much easier and more productive than eliminating an infestation.Ventilation changes the humidity of a room quickly. In fact, a vent fan attached to a humidistat is often the most effective form of humidity control. Mold was a big problem in one of the grow rooms that I visited. The room did not have a vent fan. Upon entering the enclosed room, the moist humid air was overpowering. It was terrible! The environment was so humid that roots grew from plant stems. The grower installed a vent fan to suck out moist stale air. The humidity dropped from nearly 100 percent to around 50 percent. The mold problem disappeared and harvest volume increased.Indoor horticulturists that practice all of the preventative measures have fewer problems with pests and diseases. It is much easier to prevent a disease from getting started than it is to wipe out an infestation. If pests and diseases are left unchecked, they could devastate the garden in a few short weeks.

Id switch to some kik ass expensive grow shop soil. I went with this cheap organic crap because I was on budget and ended up with whiteflies, silverfish. Just read on another thread something about sterile soil. DOnt know much about it but sounds like the crap me and you need. Bugs suck.

therein lies the problem....
get some different soil.. and different pots.
use a 10% bleach and water solution to wipe down the closet before you start another.

ps/edit:

you can sterilize soil by baking it in an oven @ 325 degrees for 90 mins.
just dont forget to add some moisture to it before you transplant or plant into the sterilized soil.
perlite shouldnt go in the oven tho.....
