autoflower tips

An excess of nutrients will cause the leaves to adopt a claw-like form, and the plant will stop growing due to salt accumulation. While it’s true that many times the growth doesn’t slow down too much, an excess of nitrogen can affect the flowering period.

This type of strains can be grown in small terraces or balconies, as they tend to produce small plants of no more than 1m in height, provided they are grown in pots. When cultivated on soil, autos can easily grow higher than 100cm, and produce more bountiful harvests than in pots.

These pots should be much taller than wide, so the roots can penetrate more deeply into the substrate and the plant can become bigger and more branchy. These containers are called 18L Automatic plant pots, or square pots, but we also recommend smart pots and Alchipots, which burn the tips of the roots creating more hairs for enhanced nutrient uptake. You should use pots of no less than 20L.

Watering autoflowering plants

A mix of white and black peat, perlite and coco is a good combination to create a quality substrate. We recommend mixing coco coir with soil to make it fluffier, and also to get lower water retention to facilitate the drainage and the drying of the substrate.

Think Different halfway its growing period

Since you’re only going to repot your seedling once, and the first container will also be the final one, the plant will always be at odds with the size of the pot.

Therefore, their vegetative period is limited to a few days, and the number of days can vary depending on the strain, but it’s usually between 15 and 30. This is the timeframe needed by automatic plants to feel mature enough to start flowering. Cannabis needs a certain amount of time to grow and start producing flowers, as well as trichomes, in order to catch the male’s pollen and be able to reproduce the species.

Cannabis growers are always on the hunt to understand the tips and tricks to maximize yields in autoflowers. Most growers have the talent, but they lack information. And that’s a serious handicap when growing autoflowers. Autoflowers grow fast and produce yields in a short span of time, but that comes only with experience. You could grow them just like photoperiod plants, but there are several stark differences.

Growers produce good yields with 24 hours, but the quality isn’t as good as plants grown in an 18/6 cycle. The light setup also plays an important role here. Although autos grow well under different types of lighting, they prefer HPS or LEDs over CFL and fluorescent lights.

5) Keep an eye on the pH

It’s also critical to transplant only after the roots have filled out in the container since the soil will drop off in clumps with the roots stuck to them. In other words, wait until the plant is a little root bound. Since there are so many conditions, it’s best to start directly in the final containers. With no disturbance, you’re all set to get great yields.

7) Use proper training techniques

Like repotting, topping, and SCROG-ing, over watering creates stress for your plants. Hence, always avoid over watering your cannabis autos and only give them water when their soil is nice and dry.

However, one constant criticism of autoflowering varieties is that they produce lighter harvests than regular strains; while autoflowering seeds have improved greatly over the last years, most growers will agree that auto harvests are a little on the light side.

Cannabis plants thrive off light. Hence, another great way to improve the yields of your autoflowering plants is to make sure they get plenty of light hours all throughout their life cycle.

Obviously you’ll want to experiment with each individual strain to see what works best on each plant given its genetics. However, some growers get great results giving their autos 18, 20, or sometimes even 24 hours of light per day.

Using airy grow mediums is a great way to do just that. Consider growing your auto plants in rockwool, perlite, vermiculite, or coco for best results.

Autoflowering plants are the latest craze in the cannabis world, and with good reason. Autos are extremely easy to grow, have short flowering times, reach manageable heights, and still produce great herb.
