best way to germinate autoflower seeds

The chamber can be used with any type of medium, Rockwool cubes, peat pellets, coco fiber, perlite, or even soil and they keep the best environment for sprouting seeds and the first days of the seedling.

Most viable seeds will sink after a couple of hours and you should see the radicle after a couple of days.

So to help your weed seed germinate, you can use a knife or any other tool with a thin point to gently insert it in between the ridges and slightly separate it, after this process, you can soak your water and germinate it like you normally would.

Step 3

So here’s how to germinate cannabis seeds with the best-known methods and a couple of tips that will get you harvesting in no time.

If they haven’t sprouted after 72 hours, add a few drops of hydrogen peroxide to kill accumulated bacteria in the water and return to the darkness for 2 more days.

The goal is to thin out the shell so that the water can reach the embryo easily, just make sure you don’t overdo it and end up harming the embryo inside.

Place the seeds in the glass and leave it in a dark place, let the seeds soak for up to 32 hours.

Maintaining the ideal temperature (between 22–25°C/71–77°F) and moisture for germination is tricky. Leaving seeds out in the open environment or on a windowsill is far from ideal; a DIY climate-controlled cupboard would do a much better service. A warming mat is perfect for maintaining a constant temperature, but it doesn’t tackle the issue of moisture.

If you don’t like the idea of pre-soaking your soil, you can use a spray to moisten the holes before you plant each seed. With enough moisture surrounding your seeds, you can still encourage a root to develop.

The soil pots will need small holes (roughly 10–15mm deep) for the newly germinated seeds to be placed into. Once the seeds are secure, you will want to place a fluorescent light 13–15cm (5–6 inches) away to encourage growth. Finally, don’t risk overwatering your seeds at this early stage. Use a plant mister to make sure they stay damp but not soaking wet.

PLANTING DIRECTLY INTO SOIL

Before you can be met with bountiful hauls of dank buds, there are several stages of cannabis growing that take precedence. Unless you can successfully germinate cannabis seeds, you won’t have a plant to harvest. Give your seeds the best possible start in life by reading our definitive guide to germination.

Your growing pots will need to be placed in a damp climate that is within the temperature range listed under our golden rules. After 4–10 days, you should see a young seedling sprout, while the roots will have begun to develop underneath the soil. The entire plant and its soil can now be transferred to a larger pot, where normal growing routines should start.

Arguably one of the least effective methods, but it is still viable. Incredibly simple to facilitate, beginner growers may opt to germinate their seeds in a glass of water. Half-fill a glass or bowl with water that is approximately 22°C (71°F).

Start by filling pots with a premium-quality soil that has been soaked in water. Many growers also choose to lace the water with a root stimulator. Make a hole roughly 10–15mm deep. This will be your seed’s new home. Remove the seeds from their packet and place them into the pre-dug holes. Loosely cover the seeds, but be careful not to compress the soil above the seed too much. The root will struggle to penetrate solid soil, slowing plant growth. Lightly spray the top of where you placed the seed so that your growing medium stays moist.

Place the plates somewhere warm (21ºC) and away from direct light.

This article explains how to correctly germinate your cannabis seeds, covering everything from optimum temperatures, to potting your seedlings and transferring them outdoors (or inside under lights).

Step 2. Germination – How to germinate cannabis seeds

Place another few layers of moist tissue on top of the seeds, again allowing excess water to drain off.

When the first few millimetres of root have emerged from a germinated seed, each one should then be carefully transferred to a small container of growing medium (soil, coco-fibre or rockwool).

Within a few days some or all of the seeds should open and put out a root. It is common for cannabis seeds to open within 72 hours of being put in the germination medium. Less commonly, some seeds may need up to 10 days or even two weeks to open and put out a root.
