Downy Mildew Treatment – What Is Powdery Mold?
Powdery mold is a type of fungus that grows on wood. It may cause white spots or brownish patches on the surface of your furniture, carpets, upholstery, etc. The spores are usually found in damp places such as basements and crawlspaces where they germinate from decaying organic matter (wood chips). They grow quickly and spread rapidly through the house if not controlled.
The fungi spreads when moisture evaporates off the surface of the wood causing it to dry out and crack. The cracks allow spores to enter the air and multiply.
Once airborne, they will continue spreading until they reach other areas of your home where there is still moist soil around. If left unchecked, this fungus can become very difficult to get rid of because spores are able to survive extreme heat or cold temperatures.
How Does Downy Mildew Spread?
When the spores land on surfaces such as carpeting, they germinate and begin growing. These mushrooms then produce tiny white or gray spores called mycelium. Mycelium travels through the air and eventually lands on another surface where it begins to reproduce again. The cycle continues until all of the mushroom growth has occurred and the spores have dried out completely.
Powdery mildew spreads from place to place by the wind, animals and people. Once it becomes established in a certain area, it is very difficult to get rid of.
The best way to prevent infection is by keeping humidity levels low and making sure all plants are free of disease and dry before adding them to your collection.
What Are Some Common Symptoms Of Downy Mold?
One of the most common signs of downy mildew is white or gray patches on your plant’s leaves, flowers, and stems. These patches may be small or cover large sections of the plant. The leaves may also develop yellow spots from the fungi.
As the fungus spreads, the leaf may turn yellow and fall off. In extreme cases, the stem and flowers can also rot away completely leaving only a stick with a few withered leaves remaining on it.
Downy mildew can sometimes cause a plant to become deformed or misshaped.
How Do I Get Rid Of Downy Mold?
The best way to prevent downy mildew from growing is to keep the relative humidity no higher than 40% in your home or grow room. This can be difficult to measure and you may need the help of a hygrometer. Most experts recommend relative humidity levels between 35% and 40% for cannabis. Try not to go below this range.
Keep the temperature of your grow room at or below 70 degrees. Going above this temperature can cause the plant to lose too much moisture through its stomata.
The stomata are the little openings on the sides of the leaves that allow the plant to breath. This stomata can close when the plant gets too dry which slows down transpiration.
Another way to prevent downy mildew is to avoid wetting your plant’s leaves whenever possible. For example, try to avoid spraying the leaves when you’re watering it.
Always allow any excess water to drain away from the base of the plant before you give it more water. Make sure the saucer under your plant is always clean and free of mold or other debris that could cause problems.
You should also avoid overhead watering. This means making sure your plant is in a pot that has drainage holes in the bottom.
If you water from above, the water has nowhere to drain. It instead sits on the soil and runs up against the stomata on the underside of the leaves. Always make sure the soil you are using drains well.
Aerate your growing medium regularly to prevent stagnant water from pooling. Water should be able to flow through the soil easily.
If you have been having problems with fungus, clean your grow room well before trying these methods again. Fungus thrives in moist, dark areas where there is little air movement.
If you are using a hydroponics system, make sure the reservoir has proper drainage. Keep the pump and all hoses free of clogs.
Don’t add nutrients that contain nitrates. Fungicides may kill the fungus but they can also damage the plant if overused.

Here’s Everything You Get
The Lighting Chapter
Learn which lighting option is best suited for you…
MH (Metal Halide) – The most widely used grow light, these give off lots of light and heat. Ideal for a very large growing area.
They work best in a space at least 4 feet tall. They are more expensive than other options.
HPS (High-Pressure Sodium) – These lights give off an orange/red light. They work best in a space at least 5 feet tall, require special lighting and are very hot.
DL (Diode) – These bulbs are the most efficient when it comes to growing cannabis. Your plants need at least 4 feet of height to accommodate the lights.
They cost more than other lighting options.
LED (Light Emitting Diode) – These bulbs are not as strong as the other options, but work well in a space no taller than 3 feet. They save money and last longer than MH or HPS bulbs.
Learn the ideal distance lights should be from your plants…
HID (High-Intensity Discharge) – Lights should be kept at least 12 inches away from the top of your plants.
DLights – Keep lights no closer than a foot from the top of your plant.
MHLights – Should always be kept 24 inches or more away from the top of your plants.
The Indoor Growing Chapter
Learn how to create a simple, low cost indoor growing setup…
Table Top – Just a table (at least 2 feet tall) and something to rest your light source on. This is the simplest way to grow indoors.
It’s also the cheapest since you probably already have a table.
Stand-Alone – A regular light fixture (with no doors) with your growing lights resting on its lid is a perfect place to start.
Garage Farm – A garage or other outbuilding with constant temperature (or at least one that can be regulated) makes a perfect place to grow.
Secret Garden – Create a secret garden in an unused space like a basement, attic, or even a closet.
Learn where you can get everything you need…
Grow Bags, Grommets, Clips, and Cables – You can find this stuff at Home Depot or any other hardware store.
Reflective Fabric – You can buy this stuff online or at a fabric store.
Grow Light – Any shop that sells indoor growing lights will have everything you need to hook them up. Most of the time, they will also provide free consulting on how to use them.
Gardening Supplies – There are many places to get these. A local shop is ideal since you can talk to the staff and get their expert advice.
The Outdoor Growing Chapter
Learn how to grow your green babies outside…
Greenhouse – This is a fully enclosed structure, like a big backyard shed. You control everything about the environment.
This is the best way to grow herbs like marijuana in colder climates. It also gives you a bit more secrecy.
Tent – A large, sturdy tent also gives you control over the environment. Just be sure it’s anchored down good.
Woods – Grew in a forest?
Just make sure no one is wandering around where they are not supposed to be and you’ll be fine.
Container Garden – You can grow just about anywhere there is sun and soil. A basic container garden can be made from anything from a clean garbage can to an old oil drum.
Outdoor Patch – A great way to go completely off the grid is to grow your plants in a field. Be sure no one will stumble across them though.
Learn what you need to consider before planting…
Climate – Where do you live?
Some places are just better for growing than others.
Electricity – Do you have access to power or will everything need to run on gas or propane?
Security – Your garden needs to be well hidden. Most people have no idea how to disguise their garden, but it’s very easy.
The Best of Both Worlds
You can grow both chemically-enhanced plants and regular ‘ol regular plants. Marijuana and Hemp plants are often grown in the same area since they don’t cross-pollinate with each other.
This allows the same piece of land to be used for two completely different types of plants. Many people think this is the ideal way to grow.
The Hybrid Way
You can harvest both types of plants at the same time. There are many strains of each plant that are bred to mature faster than others.
For example, you can grow a low-THC marijuana plant and breed it with a high-THC hemp plant to create a strain that flowers early and fast.
The Chem Way
You can buy all of your plants, seeds, and supplies at the store. This is the least natural way to grow, but it’s also the most convenient.
See what kind of garden you have.
Are you stuck with one type of garden or do you have the freedom to grow anything?
If you have the freedom then you can use all of the tactics mentioned above to create a well-rounded and diverse garden that will thrive for years. If you are limited on what you can grow, then try to maximize the benefits of the plants you can have. Some places won’t allow anything but the basic herbs. If this is the case then stick with the basic herbs.
Learn how to defend your plants…
Plant Protection – You can place traps around the garden to scare away animals and people. You can also use them to injure or kill them so they will think twice about coming back.
Alarms – A simple tripwire is effective for letting you know when someone has entered your garden. This gives you time to grab your weapon and defend yourself.
Dogs – Having a dog or dogs around your garden is another good way to let you know if someone is sneaking around. Dogs are also great defenders and will savagely bite any intruders.
Walls – A tall fence or wall will keep people from seeing what you are doing inside your garden. It will also keep people out since they won’t be able to simply walk in.
Learn what to do when the harvest is ready…
When your plants first start to flower you need to decide how you are going to harvest them. You can either harvest all of your marijuana plants at once or you can harvest the mature plants and let the others keep growing.
If your goal is to make money then you should harvest all of the plants at once so you can maximize your profit. If your goal is to have the freshest product then you should harvest the plants as they mature.
After you have harvested your plants you need to dry them out. Fresh buds will rot if they get wet so it’s important to keep them dry.
It can also take a long time for your buds to dry depending on how big they are and the humidity of the air. You can dry the buds in several ways… You can hang them up, prop them up, or lay them out. Hanging seems to be the fastest way to dry them since water naturally falls off of things that are hanging. In humid weather you will probably need to turn them every couple of hours to make sure they are drying evenly.
When your buds still have a bit of moisture in them you should put them in airtight containers. Glass jars works well for this purpose.
Putting them in baggies will allow moisture in and you definitely don’t want that to happen. When the containers are airtight they will keep the buds from getting too moist and mold from growing on them. If you have large quantities of bud then plastic food storage containers work well. These are also good for longer term storage if you don’t plan on using the buds right away. Either store your containers in a cool place (such as a basement) or add desiccants to them to help absorb any extra moisture that could cause mold.
The remaining steps to prepare the bud for sale is up to you. There are numerous ways to prepare and package the bud for consumption.
Choose whatever method works best for you or seems the most appealing.
Congratulations, you now know more than most about the cultivation and preparation of cannabis. The world is your oyster!
(Or marijuana leaf if you want to get technical).
If you find yourself in need of supplies such as seeds there are numerous ways of getting them. You can try finding a local seed bank and make a decent exchange for some of your bud or you can steal them from the local drug store (be careful not to get caught!).
If you’re really lazy, money hungry, or just plain ole criminal minded you can always resort to breaking into stores to steal what you want.
I hope this booklet has been of some help and uses. Please remember that this is only a guide and in no way implies that you won’t run into legal trouble for your activities.
Always use common sense when dealing with illegal drugs.
Good luck and happy growing!
