container size to start auto flower marijuana seeds in

2. No matter if you are choosing plastic or felt, make sure the pots have been totally cleaned and sterilized to the best of your ability. Especially if re-using the pot for a second or third run.

6. Adding a bottom layer of hydroton clay balls at the base of your pots will improve drainage and the exchange of oxygen around the root zone.

1. Decide in advance based on your space what format of growing, works to your advantage. If 1-4 large-sized plants are more practical, or if a Sea of Green has more advantages.

4. Which Pots Are Best?

For the more adventurous grower skilled in plant training, using a screen to grow your auto-flowering plants through has advantages when increasing yields. However, the screen may limit the mobility of your plants as they will be built into a net frame.

5. If you have a sewing machine, ordering a large roll of thick felt will allow you to customize your own pots, making them the exact size and shape you prefer.

You may have smaller sized plants resulting in lower yields, however, it will make up for that with the high number of plants.

It is the root zone that is responsible for the uptake and distribution of nutrients, minerals, and the distribution of growth hormone to the rest of the plant pathways. How deep and wide the root zone is will make a huge difference in what is occurring above the soil.

More than anything else, genetics will play the biggest role in determining the final outcome of your grow operation. But what makes the right strain? Well, let’s start with your personal preferences, for example, what type of effect you want from your cannabis. If you’re smoking to get blazed with the best and the latest, you can’t go wrong with THC monsters like the super dank and potent Royal Cookies Automatic or Royal Gorilla Automatic, our automatic variants of two popular strains!

How do you control your water and nutrient solution pH levels? A must-have for any grower are “pH Down” and “pH Up” products, as well as a pH meter. With these on hand, you can be in control of your soil’s pH.


Autoflowers are a class of cannabis that has only thrived on the commercial market in the last few years. Today, they are taking the market by storm with their ease of growth and great results. With these tips for growing autoflowers indoors, you can make the most of your autoflowering grow-op!

Autoflowering cannabis tends to be at its healthiest when given just the right amount of nutrients. In some cases, plants can go through the entire seedling and veg phases without any supplemental nutes, as most soil mixes already contain enough macronutrients and micronutrients to support these phases of growth.

As the lifespan of autoflowering cannabis is limited, it is less forgiving when it comes to major stressors and mistakes. When plants experience high amounts of stress, growth stalls; while this may be fine for conventional cannabis that can be kept in veg longer to recover, autoflowers don’t have that luxury—they will flower regardless. As such, it’s best to start autos in their final pot right from the get-go to avoid transplant shock.

Unless you know your cannabis very well and can accurately estimate how much water each plant will need, it is best to buy a container with holes/perforations in the bottom. In fact, you should still make your life easier and opt for holes, even if you know exactly how much they need. This allows excess water to drain and oxygen to flow through the growing medium, reducing the chance of root rot – a problem that occurs if the soil is left too wet for too long. Don’t over water – stick your little finger an inch into the soil to see how moist it is before watering.

Perhaps the most important thing when choosing containers for your cannabis is size. Most growers buy autoflowering seeds because they don’t have a lot of growing space, and they don’t want enormous plants that can reach more than six feet in height. The pot size can have a major impact on the eventual height of the plant. If you choose a small container for your autoflower seed, then it will remain short as it will quickly become root bound and the resulting stress will slow the growth of the plant.

The main disadvantage of fabric pots is that they dry out faster than ordinary pots. You will need to water them more often or use larger pots with more soil to keep this from happening. Fabric pots are also less robust than standard planters. Since they are more like bags, they are more likely to tip over.

Make sure there is enough drainage

Regardless of the variety, you choose, here are some final tips how to grow autoflowers in pots:

Ideally, you’ll want to use one container for each plant. This avoids competition among the root systems and allows you to take care of each plant individually. One plant per pot will also make re-potting easier later. If the soil in a pot is contaminated, over-watered / over-fertilized, infested with pests, etc., the rest of your plants will not suffer if each plant is given its own pot.

Next, let’s look at the different types of plant containers that are available. Any of these are fine for autoflowers. It is essential to consider the material the pot is made of – such as plastic, clay, wood, metal and even coconut fiber. Keep in mind, however, that no one container material is “best” as each has its advantages and disadvantages.

As autoflowers should not be re-potted, a container that is between 1.5 and 3 gallons should be fine. It is worth experimenting with different plant sizes to see what works best for your chosen variety. If you need your plants to remain compact, choose smaller containers; but larger pots are generally best if you want lots of vertical growth with plenty of side branches.
