Growing marijuana is increasingly becoming more and more socially acceptable within society, and each year we see a significant jump in the numbers of people those seeking to learn how to grow marijuana. In this marijuana grow guide we will explain the best way to grow marijuana indoors. Our outdoor marijuana grow guide also covers everything you’ll need to know for growing weed in the great outdoors!
Growing Marijuana Indoors
Nowadays its the preferred method of the majority of cannabis cultivators. A quick search online for a marijuana grow guide, or a trip to your local grow shop is enough to give you the materials and knowledge needed for an effective and efficient setup. Quite often indoor growers begin growing their own weed out of frustration at the lack of decent bud on offer in their local area or don’t fancy the hassle of ducking and diving from the cops when doing so.
Be warned though.. growing cannabis indoors is just as illegal as buying it on the street. The advantage is being able to do it in the privacy of your own home and not having to run the risk of ending up in a police cell every time you run out of weed. For most though, it’s for the pure joy of nurturing those little seeds as they grow into some the most robust and potent bud yielding plants you could ever have imagined!
The best thing about growing marijuana indoors is that anyone can do it! Even if you’ve never tried it before, so long as you can follow and apply the instructions listed here you can be sure of a bumper harvest at the end of your plant’s budding cycle. And for experienced growers, or even for those who may have had some slight problems with past grows, there are a few golden nuggets to be found here too! Listed below are our four important steps to indoor cannabis growing.
Choosing The Right Seeds
It’s important to choose the right seeds for your needs. For indoor growers this means seeds that are specifically designed for indoor growing. If you have yet to purchase some you can view our our collection of indoor cannabis seeds here. We have some of the top indoor strains available including white widow, northern lights, and our personal favourite strawberry ice.
Germinating Your Seeds
You can of course just drop your seeds into some moist soil and hope for the best, but by germinating them in the correct manner you reduce the risk of your precious seeds failing to produce a plant. This is particularly important when using feminized marijuana seeds. Please feel free to check our guide on how to germinate marijuana seeds.
Using The Right Soil
After choosing your seeds the next thing to take care of is the soil setup. Trust us when we say not to scrimp on the soil since it can make a huge difference to the final yield. And if you’re thinking of using unsterilized soil or any low quality mix, you run the risk of contaminating your grow room with parasites. Then later by the time you find out your grow is infected, it’s already too late. Luckily however decent soil mixes can be found in local garden centers and nurseries, and even in K-Mart, Wal Mart, online, and in many smaller grocery stores. Your soil should ideally have the following attributes :
- It should be aerated or can easily drain. Many of the best soil mixes contain some sort of sponge rock or perlite to allow for this.
- Since marijuana thrives in soil soil with acidic to base levels at natual levels, a ph of 6.5 to 7 is ideal. Soil with a higher acdity than that is a common reason for producing more males than females.
- The soil should also be capable of keeping nutrients and moisture locked in
Some marijuana growers even make their own soil mixture by mixing one measure of perlite or any other aeration material like sponge rock, with twice the amount of moss for every four gallons of soil before testing it’s ph with a ph meter, litmus paper or any other soil testing device.
If you create your own soil mix and are testing its acidity levels you’ll probably find that it’s ph has to be raised. In order to raise its ph simply add 1/2 lb of lime to every 1 cubic foot of dirt. Doing this will raise its ph by 1. And though we recommend purchasing your soil, if you do end up having to use soil you took in from outdoors, remember to first sterilize it by heating it in an oven for a little over an hour at a high temperature. Sprinkle some water on before hand and be prepared for a strong earthly odour as your soil bakes in the heat. When that’s done just throw in 2 or 3 teaspoons of fertilizer (Rapid-Gro perhaps) and your good to go. However as mentioned, growing cannabis indoors is a hell of a lot easier with some cheap potting soil instead!
Marijuana Grow Pots
The next thing to check off your list are the grow pots your plants are going to need. If you aren’t using brand new pots, then it’s important to sterilize any old pots completely, and especially if they’ve been previously used with any other plants. The overall size and yield of your finished plant corresponds directly with the amount of room you can give it’s roots to grow, so it’s best to choose a container which is big enough to allow for this. Since ideally your plant shouldn’t be re-potted more than once, choose the best containers you can and stick with them. Transplanting your plants even once can shock a marijuana plant, a extra time is required for it to begin growing at its normal speed again.
The original containers you choose to grow your plants in should ideally be no larger than five or six inches in diameter, and can be made of clay, plastic or as mentioned in the next paragraph – jiffy pots. When its then time to transplant your plants to a larger pot, firstly you should have their new homes prepared by filling them with soil and then scoop out a hole just the same size as that of the previous smaller container. Place one hand on the soil at the top of the pot and allow the plant to catch between your fingers and gently flip the whole pot over. Gently pull the old container away, tapping it gently if you have to in order to release it from the roots. Treat it as though it is a sandcastle at this stage and gently place it into the larger pot before covering with soil and giving it some water.
Jiffy pots make the job of transplanting a lot easier. They are made out of compressed peat and when your seedlings begins to outgrow them they can be transplanted as a whole into their new homes. The roots of the marijuana can then find their way through the damp decomposing jiffy pots and begin to make their downward journey sucking up nutrients as they go. Ensure your containers have a volume of at least 3 gallons. Cannabis roots need an aerated medium to live in do not like their roots becoming pot bound. Keeping this in mind will save you having to transplant your plant when it’s fully grown in the future.
The small plants should be ready to transplant into their permanent homes in about two weeks. Keep a close watch on them after the first week or so and avoid root binding at all costs since the plants never seem to do as well once they have been stunted by the cramping of their roots.
Feeding Your Plants
While cannabis plants do love their food, feeding them too much fertilizer can damage them. If you’ve purchased your soil from a shop then it should come with enough nutrients to feed your plant for it’s first 3 weeks. After that you should begin gradually introducing fertilizer, initially with half the recommended fertilizer dosage and then work your way up.
During your plant’s vegetative stage it requires a fertilizer high in Nitrogen. Then later as it reaches it’s budding stage the nutrients should be switched to one higher in Potassium. A good mix of both as well as other one that includes the other other important elements for a healthy marijuana plant are often used. Rapid-Gro, Eco Grow, and Formula Flora are some of the top fertilizers for growing marijuana indoors on the market today.
The acidity levels of the soil almost always raise when fertilizer is added to the mix. However these fertilizers are especially good for cannabis since they prevent the soil from becoming too acidic.
