how to grow autoflowering weed

Photoperiod strains need to be on a 12-12 light schedule to initiate flowering. When growing outdoors, photoperiod plants naturally start making buds as winter approaches and days grow short. However, most indoor growers put their grow lights on a timer to initiate and maintain a 12-12 light schedule during the flowering stage until harvest. This need for uninterrupted darkness is why it’s important to create a light-proof growing environment when growing photoperiod plants indoors.

Outdoors, your yields depend a lot on your climate. Warm and sunny weather with many hours of light a day will produce plants with bigger yields.

I hope these two examples help show why it’s important to get the right auto-flowering strain for your goals and setup! If you want a small, fast plant you won’t be happy with your results if you purchase a tall strain, or vice versa.

Once the flowering cycle is initiated, your plants are more “set” as far as their overall health and structure. Once a cannabis plant starts budding, there is basically a countdown until buds are ready to harvest just like autos (this amount of time is mostly based on the strain). Though the plant may have an initial last “stretch” of vegetative growth when the light cycle is first changed over, as the plant approaches harvest towards the end of the flowering stage, almost all growth halts except for the development of bigger buds.

Unlike traditional (referred to as photoperiod ) strains, autos don’t need any special kind of light schedule to “tell” the plant to start budding. With a photoperiod strain, a cannabis plant needs 12+ hours of darkness a day to initiate flowering.

These are my 4 x Fastbud #2´s (this strain has now been bred into Ice Cool Auto, which may be even better). I chopped 2 a couple of nights ago and the others today. Day 65 from seed under a mixture of 400 & 600W HPS.

When growing photoperiod plants outdoors, it’s important to make sure you plant your seeds at the right time and choose a strain that is suitable for your climate.

Auto-Flowering Strains.

These two auto-flowering plants are also the same age and and grown in the same environment! The small plant is Auto Chemdawg & the huge plant is Super Lemon Haze Auto.

Auto plants are suitable for growing outdoors in almost any climate that has at least 2-3 months of warm, sunny weather every year.

Smell, Taste and Visual Appeal – When it comes to smell & taste, the same rules apply. While there are fewer auto-flowering strains to choose from (though the list is growing each day), the smell and taste of each strain is similar to their photoperiod counterparts.

Do autos need a special light schedule to start making buds?

Do auto strains needs a special light schedule? In a way, yes!

Most indoor growers report getting great growth rates when keeping light schedules on an 18/6 light schedule (18 hour of light and 6 hours of dark each days). 20/4 is another popular light schedule for indoor auto plants. Some growers will give 24 hours of light to auto plants, but others believe that auto plants develop better when given at least a few hours of darkness each day.

Auto-Flowering vs. Traditional Cannabis Strains.

CBD is a cannabinoid that is known for having medical and anti-anxiety properties. Most photoperiod strains these days are high THC, low CBD, and it can be hard to find high-CBD photoperiod strains. Learn more about THC vs CBD.

Photoperiod.

For beginners, germinating the seeds is an important part of the entire process. To get better results, soak the seeds in plain water for at least 24 hours and wrap them in moist paper towels for a day or two. Use a ziplock bag to store the towels.

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.

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.

2. Time it right.

It’s important to start autoflowers in their final containers rather than planting them in smaller ones and transplanting them later. Sure, growing cannabis is like growing tomatoes, but autoflowers have a limited time period and can’t afford to lose days while the plant settles and searches for roots.

Here’s a quick table to help you understand pH better:

This may vary according to the genetics and growing environment, have in mind that it’s just to give you an idea of what to expect, some autoflowers may take less and others take longer.

After all, a plant that gives you lip-smacking buds in just 2 months deserves some research, eh? Autoflowers may scare you at first, but if you avoid a few common mistakes, you’ll harvest much more than you can imagine, and it only gets better.

You’ve come all this way, and the end is almost near, so don’t screw this up now! Now you’re probably asking “ how to tell if my autoflower is ready for harvest? ” Well, after you’ve put in all the hard work, wait for the right time. Growers use microscopes to check the trichomes that usually indicate the right time, but you can harvest when at least 50 to 70 percent of the pistils are amber in color.

It’s important to keep the towels moist because the seeds can rot if there’s too much water. Similarly, the seeds won’t sprout if the towels are completely dry. Don’t make the mistake of directly planting the seeds, especially if you’re doing it for the first time. Once the seeds show a tap root, plant the seeds in the final container .

Macro and micronutrients.

In general, autoflowers stay for 4 weeks in the vegetative stage, so about 4 weeks . Then your auto will start developing flowers for 3 weeks, and fattening up the buds for the last 3 weeks.

And this is true for all plants. Can you expect to grow tomatoes if you’re clueless about using nutrients? Or, can you harvest cucumbers if you don’t even know when to harvest them? No? Similarly, autoflowers need you to follow a few basic guidelines like other plants, and you’ll do just fine if you take the time to understand them.

Please don’t stuff seeds in plastic containers that make life hell for the poor roots. Use porous containers such as fabric pots or even Airpots to help the plants grow as much as possible. Autoflowers are typically small, but they need containers that are at least 5-8 liters in size.

A way to check if the soil is dry is to use your index finger and stick it in the soil, if it comes out moist then the soil is still humid, although by doing this you won’t be able to know if the bottom is still wet so in order to get the timing right, lift the pots and check the weight.

6. Do not transplant.

Autoflowers are really easy to grow but there are basic guidelines you should know, just like when growing other plants or vegetables. All plants are different and even though you can successfully harvest the first time you grow cannabis, there are common mistakes that are better to avoid.

For example, cannabis needs more nitrogen in the vegetative stage. In the pre-flowering stage, nutrients with more phosphorous are preferred, and in the flowering stage needs a lot more potassium than nitrogen or phosphorous.

This solely depends on your climate, you need to remember that autos prefer dry sunny days so if you’re planning to have just one grow cycle, you can start them 1-2 weeks into Summer , and if you’re planning to have 2 harvests, start the next one right after finishing the first one.

The yields depend on genetics, environment, stress, growers skills, and etc.. But in general, you can expect between 50-110 grams per plant .

Autoflowers (aka self flowering seeds) are suited for beginner growers but it’s crucial you know the basics if you want to have a successful harvest the first time you grow cannabis, although you can learn as you go, it can be disappointing if you waste time and money, and end up with nothing to smoke.
