how to grow weed from seed without lights

Firstly, the pot must not let sunlight through. Roots are not resistant to this. Therefore, it is best to choose a dark pot. Secondly, the pot must have drainage holes so that excess water can easily drain away.

The first step to successfully grow indoors with natural light is to find a sunny spot in front of the window. Preferably on a windowsill in front of a window facing south. That’s where your plant will receive the most light.

No sky-high energy bills, no unwanted eyes, no grow tent needed and a cannabis plant grown in a completely natural way! Isn’t that what everyone wants? Especially when you are growing for the first time!

Step 4: Choosing a cultivation medium

Tip
Place a (matching) saucer under the pot, so you can collect excess water.

This way of growing is also called window farming and is very popular in Canada, America and Australia. The popularity is not surprising when you look at the advantages of growing without grow lights.

In step 3 you choose a pot to grow in. The pot must meet at least two requirements.

Let’s start with some basic knowledge for the indoor grower.

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.

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.

Photoperiod plants need to follow a specific light schedule, particularly during the flowering period. These plants need 12 hours of complete darkness to induce flowering and throughout the flowering phase until harvest. “If you can’t get the environment dark enough, that plant is just going to keep on growing and might get too big for the space you have,” added Jimmy. Our homes are full of light, so to assure the darkness needed to induce flowering, put the plants in a closet each sundown and back out in their window each morning.

Autoflower vs photoperiod plants: what's the difference?

Flush your plant before harvesting. If you’ve been feeding your plant with synthetic nutrients or fertilizers, you’ll need to give it a good flush before harvesting. By flushing the growing medium of nutrients and fertilizers, you’ll leave the plant to use up its reserves before harvesting. It’s an important step that, if skipped, can negatively impact the final quality of your flower. Timing is important here because you don’t want to strip your plant of nutrients too early. One to two weeks before harvest is a good rule of thumb.

Keep it simple to start. When it comes to your setup, “I would challenge people to try doing as little as possible on their first plant and adding in effort or equipment only to solve issues as they arise or to better future plants,” shared Jimmy.

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.
