The Cannabis Under the Stairs – Part 2

Cannabis is legal to grow in many of our United States. If you’re able to grow, you should. It is easy, fun, educational, and not very expensive. The first post: The Cannabis Under the Stairs, assembled the equipment needed to start growing in a closet. This post is about the setup of the growing medium in your newly constructed microfarm. Hopefully this quick guide will inspire YOU to start your first grow.


Now that the grow tent is setup for growing Cannabis in a closet under the stairs, the growing medium needs to be considered. At this point a decision needs to be made: soil or hydroponic? I have been growing with soil for nearly two years. For me it was less expensive and easier to go with soil. I hope to give a hydroponic grow a try some day when I feel more confident with my growing skills and I can expand my grow area.

Making a soil mix that will maximize growth is not difficult, especially these days. With the legalization of Cannabis, growing stores are popping up like Starbucks! Additionally, more companies are competing for farmers’ dollars with specialized Cannabis products including premixed “megasoils”. How much soil mix to buy/make depends on the number pots and the size of those container. There are approximately 7.5 gallons per cubic foot of soil. The soil bags are usually clearly marked in cubic feet.

Remember, a little research goes a long way. Here’s a list of soil companies to check out:

Adding some Perlite will lighten the soil and help with drainage, letting the soil dry out between watering. Perlite is a volcanic mineral that is treated to create properties to aid with soil aeration and water retention. Perlite retains some water but more importantly, it traps oxygen on it’s textured surface keeping the soil aerated. I usually put in a handful of Perlite per pot and mix it in well. If you choose a Cannabis premix, check to see if the Perlite might already be in there. Once the soil mix is ready, the container must be considered.

Since a tent is limited in area, the pot size will be limited as well. A larger pot will yield a larger plant and a smaller pot will yield a smaller one. The correct size not only dictates the number of pots in the tent but how big the Cannabis could grow. It is important to remember only one Cannabis plant should be in each pot. Also keep in mind there are growth training techniques that maximize yield per area but, as a beginner, they are best tried after a few successful grows.

The bottom of the pot must have a layer of small stones so the soil can drain freely. Of course, you’ll need a tray under that pot to catch the water that will leak out from the drain holes. Use those clear plastic trays that raise the pot a tiny bit above the water. They cost about a buck at most garden stores and will keep water off the floor of the tent.

The tent I am using is 48 inches by 24 inches. I start with 8 plants in the tent but, as the Cannabis grows, I will remove any male plants as well as the weaker ones so that 4 plants remain. The foliage and buds of the four Cannabis plants will completely fill the tent by the time they are ready to harvest.

It is time to get some seeds or clones and get this party started. But that’s a post for another day.
