How to Avoid Pests in Your Marijuana Garden

Once pests have invaded your marijuana growing room, it will take an awful lot of time and effort to get rid of them, and it’s likely that they will damage your plants in the process. Marijuana plants which have to fight off a pest invasion have much of their vigor sapped way, and it becomes less likely that they will achieve their maximum potency and growth. It is far easier to protect yourself against a pest invasion right from the beginning, than it is at any other point in the growth cycle. Here’s how you can go about doing that.

How to Avoid Pests in Your Marijuana GardenMake sure your space is secured

A well-configured growing room is your first and best line of defense against external interference from pests, so you should spend whatever effort is needed at the outset to secure your plants against any kind of external invasion. The two basic principles involved in securing your growing room are: making sure that it’s completely sealed off from the outside environment, and arranging things so that the room can quickly and easily be sanitized. A good start for handling both of these requirements is using white or silver Mylar, because it’s easy to clean, and it’s easy to apply to the walls of your room. If you’re using a grow tent, this will probably have its own protection against the outside environment.


Once you have secured your growing room from any external interference, you need to turn your attention to yourself, because the next way contaminants can be introduced into your growing room is if you bring them in. It’s a good idea to get in the habit of changing your clothes as you enter your growing room, because pests are great at attaching themselves to clothing and equipment. Spending a few minutes cleaning your clothes and your equipment will be worth it, in terms of the health of your plants.

Using seeds

Your best bet for keeping pests out of your growing room may start with using seeds, rather than pre-germinated plants. Since there’s no way you can be sure about the growing environment that young plants were raised in, that involves a risk of pest introduction. By raising your plants from seeds, you can be sure that sterile conditions have prevailed throughout their entire life cycle.

Soils versus other media

Even the growing medium that you raise your plants in has to be kept free of pests, and soils can often contain varmints that will cause problems for your plants. If you do prefer to use soil, make sure you buy it from a trusted source. Other growing media such as hydroponic setups, rockwool, or clay pellets are generally safe, and free of pests.

Sticky fly traps

It’s always a good idea to hang up a few sticky fly strips in your growing room, just to see if anything is buzzing around. The best-case scenario is that no pests ever get stuck to your fly strips, but if you do see some, it’s time to spring into action and do the whole sanitizing routine before things progress to some kind of pest outbreak. If you can follow all of the recommendations described above, you can be fairly confident that you will avoid any serious outbreak of pests in your growing room, and that your cannabis plants will reach their full potential.

How to Use Light Deprivation for Controlling Cannabis Growth

How to Use Light Deprivation for Controlling Cannabis Growth

It’s pretty well known that light is one of the essential components for cannabis growth – so why would you want to deprive the plants of that essential light? The answer is simple – to control growth, and achieve the best benefits of both indoor and outdoor growing operations. There are a good many reasons why you would want to exercise that kind of control over your plant growth, beginning with the fact that your cannabis plants would not be subject to the uncertainties of outdoor weather.

Being developed inside some kind of greenhouse setup allows them to have ideal climate control at all times, assuming you have fans and humidifiers included in your setup. Perhaps best of all, multiple high-quality crops can be produced in one year. Because you control when the plants changeover from their vegetative state to the flowering stage, you can also maximize their health beforehand, prune plants perfectly, and wait for the ideal stage of growth before letting them go to flower.

Inexpensive setup 

To setup a relatively cheap light deprivation growing facility, you can build a simple ‘hoop house’, using PVC, rebar, some fans, a light deprivation tarpaulin, and several wooden 2×4’s. After selecting your growing space, you’ll need the help of a friend or two to help erect the hoop house, and cover it with the light deprivation tarp. Usage of the tarp is critical to your operation, and it needs to manage growth by permitting light in at the same time every day, or the plants will quickly get out of whack. Once you’ve established your basic light cycle, stick to it as much as possible, and then control temperature and humidity by having openings in the hoop house, and using the fans to manage air flow.

Moderately-priced setup 

A permanent greenhouse is a step up in cost and also in the stability of your light deprivation setup, since a permanent structure would not be as susceptible to strong winds like a hoop house might be. Instead of having to manually operate your light deprivation tarp, it could be setup on some kind of pulley system, so you don’t have to go through manual labor in your light cycle routine. It will also be easier to setup your irrigation method, heaters, fans, and humidifiers in a permanent structure.

High-cost setup

If you have the means for this kind of setup, it can be highly productive and much easier to operate. This involves a permanent greenhouse system, entirely automated and controlled by computers. All aspects of growing, i.e. temperature, humidity, air flow, watering, and light can be at the direction of a pre-set computer program. By including interior light sources, your control over lighting becomes even more detailed and precise. The benefits of all this expense can make the cost worthwhile, as you can produce a number of high-quality cannabis crops every year.
