autoflower grow

Autoflowering cannabis plants are hardy, fast, and easy to cultivate in confined spaces. What’s not to love? Learn how to grow them week by week below.

Because of this unique trait, outdoor growers can achieve multiple harvests during a single growing season. By germinating seeds week after week in early spring, you can theoretically rake in your first harvest after

HOW LONG DO AUTOFLOWERS TAKE FROM SEED TO HARVEST?

Many growers elect to cultivate autoflowers because of their speedy growing rate. Their hardy genetics and forgiving nature also make them easier to grow and therefore more beginner-friendly.

If you’re wondering what the term “N-P-K” printed on fertilizer bags means, it’s nothing but Nitrogen-Phosphorous-Potassium. The plants also need other micronutrients along with calcium and magnesium, so it’s extremely important to get the dosage right.

Frost must be avoided at all costs. Typically, most growers begin planting when spring is just around the corner. Depending on where you live, you can plant the seeds as soon as the frost clears. If you reside in a location that doesn’t receive any snow, go ahead and plant when the temperatures range between 22°C to 28°C (71°F to 77°F).

6. Do not transplant

Yes, you can, although it’s not recommended because it can affect the yields. To prevent shocking your autoflowers and consequently affecting yields, it’s recommended to transplant 7-12 days after germination and if possible, use rooting cubes to prevent damaging the roots.

Most plants die if you over or under-water them. Yes, autoflowers need water to grow, but it’s critical to supply it only when the plant needs it. It’s obvious that the timing is important even when the plants need water.

Often referred to as popcorn buds, the lower portions stay small. However, harvesting the main colas and leaving the popcorn buds on the plant for a week more will increase yields dramatically. Be patient, and let Mother Nature do the rest for you! If you avoid these common mistakes when growing autoflowering cannabis, you’ll soon be rewarded with potent resinous buds that will last a long time if stored properly.

The successful autoflower grower will also fully understand the importance of optimised grow room conditions. Avoiding wild fluctuations in temperatures/humidity and maintaining your autoflower plant in the ‘sweet spot’ of steady environmental conditions is key. Avoiding over feeding and under feeding is one of the more important rules. If you can maintain stable, optimised grow room conditions and if you can combine this with good cannabis genetics then you should be set for a great harvest!

Autos are potent too, on the same quality levels as the best feminised strains. But what causes the occasional auto to remain small and ‘dwarf like’? Is it always down to poor quality seeds? Or are there any professional tips and tricks to get the best from your autoflower seeds? Read on for expert advice.

Your autoflower is root bound (not enough root space)

Experienced autoflower growers will use a proven grow medium which is usually light and aerated. They will often use plant containers such as airpots or felt sacks. These allow greater levels of root oxygenation. Remember, healthy cannabis roots mean a healthy cannabis plant.

The professional cannabis grower may also invest in a light meter which will accurately measure both the power and the spectrum of the LED light at canopy level.

A good practical example of this can be seen with the high quality Fluence LED grow lights. Consider the Fluence SPYDR 2x (330w) and Fluence SPYDR 2p (645w) (note that there is also a Fluence SPYDR 2i at 630w). All the lights are made for a 1.2m x 1.2m grow room. The 330W SPYDR 2x is perfect for autoflowers under 20hours of daily light. However, in the same tent both the SPYDR 2p (645W) and SPYDR 2i (630W) are simply way too strong to be used for autoflowers on a 20/4 schedule and you will risk light burn on both the leaves and flowers.
