best way to grow autoflowering strains indoors

You’ve reached the best part of this autoflower grow guide – the end. Depending on your specific strain, you may be ready for harvest anywhere from 10-12 weeks. You’ll know it’s time when most of the trichomes are whitish, and the pistils are brownish-red.

It takes usually 3 days for autoflowers to germinate. This process is when the seeds come alive. The root travels into the soil and leaves sprout above ground.

This characteristic makes growing autoflowers outdoors perfect when you want to take advantage of mother nature’s natural light source. Whereas most plants can only grow during a specific season, autoflowers can successfully pull off two to three seasons instead of one. As long as you germinate your seeds by the beginning of spring, protect your plants from extreme temperatures (the 90s and above), and the humidity stays between 70 and 90%, you can enjoy a very long outdoor growing season.

Week 7 – 8: Monitor and prepare

To start germinating your seeds, you will need the proper soil mixture. In general, autoflowers will need fewer nutrients than regular seeds; still, they will need rich potting soil to help support their rapid growth.

The downside to an autoflower grow is that the yields will not be as large as traditional seeds. However, a smaller yield on something you are nearly guaranteed to be successful at is better than no yield from something a bit harder to grow. If it’s your first time growing these quick-growing seeds, try using an autoflower grow journal to document your journey. This way, there’s a record of your work, and you can improve upon it in the future.

Grow Year Round

Metal Halide lights are usually used during the vegetative phase of growth, but can also be used during flowering. Their bluish light is perfect for vegging plants, and while this will get the job done, many dedicated growers switch to another lighting solution once buds start to form.

Soil is what millions of years of evolution trained cannabis seeds to grow in, and there’s nothing wrong with germinating, planting, and trusting the plant’s genetic to take care of the rest. The only caveat we have to add is that you find high-quality soil, either on the internet or your local hardware store. Cheaper, low-end soil is meant to grow small flowers, not giant cannabis bushes. In our experiments with bargain brands, we’ve found that plants grow quite well through the vegetative stage, but the once flowering starts our plants quickly exhaust the available nutrients and begin showing signs of malnutrition. This problem can be corrected with the addition of outside nutrients, but it’s just easier to buy high-quality soil in the first place.

Autoflowering seeds grow, well, automatically when cultivated outdoors. Plant, water, and fertilize them, then let the sun and mother nature do the rest. Indoor growing is more technical, but just a bit. Whereas the Earth and the sun provide abundant soil and light, you’ll have to provide those for your plant. You’ll also need to pay a bit more attention to plant nutrition, as well as install a carbon filter to keep the smell away unless you’re like us and want your home to smell like fresh marijuana all the time. Here’s all you need to know to get started growing autoflower weed indoors.

In general autoflower strains are almost always hungry for calcium and magnesium, so you should get a brand that provides those vital nutrients. Beyond that, don’t stress over it. The growing environment and medium, more than strain, determine what kind of nutrients you need to provide your plants. Since those are unique to each grower, it’s hard to give generalized advice.

You’ve probably seen Compact Fluorescent Light bulbs in your own home. They’re easy to find anywhere light bulbs are stored. They’re cheap, small, and easy to find, making them perfect for private-minded growers with limited space to grow. Unlike other fluorescent bulbs, you’ll want to keep CFLs close to your plants to make sure light reaches lower leaves and bud sites.

Some growers also flush during the pre-flowering stage, when the plants are transitioning from the vegetative into the flowering stage so they can start feeding from zero, as said above, this won’t hurt your plants but should be done properly.

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.

So, if it’s your first time, stick to commercial nutrients. And, the topic on nutrients is incomplete if you don’t talk about pH. Depending on the medium 2 you choose to grow, the pH must be regulated accordingly. Cannabis plants love acidic soil, so the pH must be maintained between 5.5 to 7 in both soil and hydroponic setups.

8. Overfeeding and underfeeding

Most autoflowers reach a height of around 50-100cm but a plant’s size depends on the genetics and growing conditions. Also, all strains are different so you will find Sativa and Indica-leaning autos; Most Indica hybrid autoflowers will stay around the 80-120cm mark but Sativa-dominant autoflowers can reach up to 175cm tall.

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.

To set things straight, let’s begin by saying that autoflowers are really easy to grow. In fact, beginners can try growing autoflowers with little to no experience as long as they understand the basics 1 .

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.
