A: I actually never recommend starting a marijuana plant from seed, because you have to determine whether the seeds are male or female, which is difficult. Only female plants produce the flowers that are most desirable in terms of cannabinoid content. Male plants are pretty much unusable (for smoking purposes).

An overview of the basics

Q:What’s next after obtaining clone plants?

So the best place to grow marijuana is in a room in the basement with a locked door so light doesn’t inadvertently get in when the plants are “sleeping.” If you don’t have a basement, a small closet with light-leak protection around the door will work.

Getting to harvest

First and foremost, you’ll want to use an autoflowering cannabis variety when growing on a windowsill. Unlike photoperiodic strains, autoflowers do not flower based on a changing light cycle. Instead, they start flowering automatically once they reach a certain age. This is really important when growing on a windowsill, as you won’t have enough control over your lighting to force a photoperiodic strain to flower.

If you want to stay away from fertilisers, you can take the time to prepare your own soil before you decide to plant. You’ll still start with store-bought soil, but over a period of months you’ll enrich that soil with all kinds of ingredients to create a nutrient-rich medium for your plants to grow in.


Not everyone has a good outdoor space to grow cannabis, nor is willing to invest in expensive indoor grow equipment. Meanwhile, most people will have at least one windowsill in their apartment. And while it’s far from optimal, it is possible to grow a healthy cannabis plant on a windowsill. Here’s how.


Leave your seedling to grow until it has developed a few nodes and at least one leaf with a full number of fingers (this will range between 7–13 fingers, depending on the strain). Once you see its roots growing from the bottom or side of the plastic cup, it’ll be ready to move into a bigger pot.

Not necessarily. “The more effort and energy you put into a plant, the bigger and better your harvest will be,” said Jimmy. “I think that’s a pretty universal truth in the gardening game, but I’ve definitely been surprised by how well plants can do without the elaborate tents, fans, filters, feeding systems, and so on.”

Rotate your plant. “Growing with just a window, your plant is going to bend itself towards the light constantly and will benefit from regular rotating. I was rotating my cannabis plant twice a day to keep it growing relatively upright,” said Jimmy.

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.

Autoflowering plants begin flowering automatically based on their maturation. When they reach a particular age, they flower, regardless of how much sunlight/darkness they are getting. These plants do not require the complete darkness that photoperiod plants do, meaning you could leave them out and about overnight and they will be fine. Another reason you might want to choose an autoflower variety is if you’re short on time since their growth cycle is shorter than it is for photoperiod plants.

Experience is the best teacher when it comes to growing cannabis — or any plant for that matter. Consider these tips before embarking on growing weed indoors without lights.
