Many hobbyist growers elect to use grow tents, closets, or other enclosed spaces when growing cannabis indoors, often outfitting these spaces with lights and even humidity and temperature control systems. Depending on your level of interest and enthusiasm, these systems can cost anywhere from hundreds to thousands of dollars.
But can you simply stick a cannabis plant in a nice sunny window and let it do its thing? Read on to understand what to expect if you choose to grow cannabis indoors au naturel, along with a few tips and tricks from experts to help your indoor plant thrive in a minimal setup.
Consider your indoor climate when choosing a strain
Successfully growing a cannabis plant indoors is all about covering the plant’s basic needs: air, light, temperature, water, and nutrients. So, if you get those things right, your homegrown cannabis plant could provide much more than a fun experiment. And considering that indoor cannabis plants can grow a few feet tall and equally wide, you should anticipate young plants to take up more space by the time they reach maturity.
When growing in your home’s natural environment, choose a strain that will best match up with the general temperature and humidity of your home. If you use air conditioning in the summer, then you might want to select an indica-dominant cultivar that can thrive in milder temperatures. If your home is hot and humid during the summer, then a sativa-dominant strain might be a better choice.
There are two types of plants a grower might consider: autoflowering varieties or photoperiod varieties.
Will growing a plant indoors without grow lights leave you with wonky plants? Lower yields? Less potent flower?
Be a good plant parent. Keep an eye on its growth and development. Trim yellowing or dying leaves that often present at the bottom of the plant when they get shaded by the top canopy. Keep an eye out for insects and act quickly when you see them, then continue monitoring closely because pests and disease can be persistent and difficult to get rid of.
When it comes to pot sizes, you’ll want a small pot (1 gallon or less) for seedlings, but you can also just use a plastic cup. After that, you want to transplant the plants into ever larger pots.
2. Get Pots And Soil
Since we’re keeping the process simple, I’ll leave it at the bare necessities. If you’ve only got a cannabis plant or two, you’ll be fine with that.
I know many beginning indoor cannabis growers want to spend as little as possible, so they start by growing bag seed. I did this myself, so I won’t tell you not to, but you should be aware of the problems you may face.
