How to Grow Autoflowering Cannabis Strains

In order to grow autoflowering cannabis strains, you have to prepare some important things. In fact, they can be able to grow quickly. Let’s take a look at these tips for the success in your gardening.

Training Your Plants

It’s important to train your plants in their vegetative growth. This period is short for autoflowering cannabis. In fact, it just should be 2 weeks for the limit.

In order to start, you should top them after developing three nodes so as to promote a more even canopy. Besides, you can also consider pulling it down in order to create new upward growth.

When they do begin flowering, don’t top them. Then, prune them for no more than 7 days into flowering.

Climate Considerations

Growing autoflowering plants means that you are letting them flower when they need to be in vegetative growth.

It’s not essential to follow photoperiod light cycles. Therefore, many growers start these plants early in the season of Mar or late in the season of Sep. During this time, you still need to keep them warm to grow.

To combat the risk of rot, you should grow them in a greenhouse in order to give them protection from the elements.

Go Easy on Feeding

For autoflowering plants, you needn’t feed them heavily because of their small size. Also, they have a short amount of time in the vegetative cycle. You just need to feed them very lightly.

They require a small number of vegetative nutrients when your plants reach two weeks of life. Feed them a higher amount of nutrients gradually over time till they’re six or seven weeks old.

Harvest Gradually

These plants don’t have time to develop a canopy. That’s why you keep buds lower down on your plants. This is also the reason why you should harvest them sequentially.

It seems to not easy to choose the time to harvest. Normally, you have to check your plant’s trichomes to know when 59% of these plants are amber.

Keep in mind it’s important to stop watering your plants 1 or 2 days before harvesting them.

Prepare Your Next Crop

If you want to receive the most out of autoflowering seeds, you should prepare your next batch of plants. That’s why it’s best to pop seeds before harvesting the current plants.

Because you are growing autoflowering plants, there may be some plants which just start out in the same room.

Don’t Over-Water

Avoid giving your plants too much water because the roots may be suffocated. Then, they can’t carry nutrients to the plants. If you over water your plants, you will have to face stunted growth. And, this may be a nutrient issue.

It’s best to weigh them with their pots dry. You just need to add 5% or 10% to that weight.
