Choosing the best pot size for autoflower seeds is a critical step in your cannabis cultivation journey. Too small, and your plants may become root-bound, hindering their growth. Too large, and you could waste valuable resources. In this guide, we’ll explore the optimal pot sizes for different grow methods, from LST training to SOG growing. We’ll also compare different pot types, including Hempy buckets, Smart Pots, Air Pots, and Terracotta, discussing their advantages and drawbacks. And lastly, we’ll touch on why transplanting autoflowers can harm their yield. So, if you’re wondering about the perfect pot size for autoflowers, read on to find out more.
How Many Autoflowers Can You Fit in a Grow Tent?
The number of autoflowers you can fit in your grow tent primarily depends on three factors: the size of the plant, the size of the pots, and the training methods used. Certain training techniques such as Scrog (Screen of Green) take up more room per plant than others like SOG (Sea of Green). Let’s delve into this further.
Estimated yield according to pot size
Let’s start by looking at a simple comparison of different autoflower pot sizes and the yield they can provide. The following table outlines the yield of a cannabis plant in various pot sizes:
| Pot Size (Liters) | Expected Yield Per Plant (grams) |
| 3L | 20-50g |
| 5L | 50-80g |
| 10L | 80-150g |
| 15L | 150-200g |
Number of autoflowers you can fit into a tent
When it comes to fitting these pots into grow tents of different dimensions, you can use this table as a guide.
| Pot Size (Liters) | 2ft x 2ft Tent | 3ft x 3ft Tent | 4ft x 4ft Tent | 5ft x 5ft Tent |
| 3L | 6 – 12 | 8 – 16 | 12 – 24 | 20 – 30 |
| 5L | 5 – 10 | 6 – 12 | 10 – 20 | 15 – 24 |
| 10L | 2 – 4 | 5 – 10 | 8 – 16 | 10 – 18 |
| 15L | 1 – 2 | 4 – 5 | 6 – 8 | 8 – 10 |
What is the Best Size of Pot for Autoflowers?
If you’re aiming to maximize yield, using larger or very large-sized 15L pots may be the best way to go. This is particularly true for indoor growers who use training techniques like Scrog, which widen the plant structure, requiring bigger pots. The bigger the pot, the more room the plant has to develop a robust root system, thereby increasing its potential yield.
What Sized Pot for LST Training Autoflowers?
LST or Low Stress Training is a technique that involves bending and tying down plant branches to create a more flat and wide canopy. When employing this method, larger pots are best, because they provide more room for your autoflowers to expand and thrive, thus optimizing yield per plant. However, this also means that the plant will occupy more space in your tent, reducing the number of pots you can fit.
Although don’t worry too much about this because the extra yield per plant should more than make up for the reduced number of autoflowers.
What Sized Pot is Used for SOG Growing?
SOG or Sea of Green is a method where a high number of plants are grown in a confined space. The aim is to create a green canopy that captures light efficiently, enhancing the overall yield. When employing this method, you’ll want to use many smaller pots. This won’t result in a high yield per plant but, when summed up, can provide a sizable harvest with relatively low maintenance.
The SOG method is ideal for the indoor autoflower grower that wants to minimize the amount of time spent training plants whilst still maximizing production.
What is the Best Type of Pot for Autoflowers?
The material of your pot plays a crucial role in the growth and development of your autoflowers. Let’s explore the advantages of different types of pots.
Smart Pots
Smart Pots are fabric containers that allow excellent breathability, helping to prevent overwatering—a common beginner’s mistake. Their flexibility also enables more comfortable transportation and storage.
Air Pots
Air pots are designed to enhance air circulation and drainage, promoting a healthy root system. However, they might require more frequent watering, which can be challenging for novice growers to manage.
Hempy Buckets
Hempy buckets are a simple and inexpensive form of hydroponics. They offer excellent water and nutrient delivery, but may be a bit challenging for beginners due to their sensitivity to pH levels and nutrient concentrations.
Terracotta Pots
Terracotta pots are inexpensive and readily available, making them a popular choice among growers. However, they can heat up quickly and have suboptimal drainage, factors that need to be carefully managed to ensure plant health.
why shouldn’t you transplant autoflowers?
Autoflowers are typically planted in their final pot from day one. Their life cycle is much shorter than regular cannabis plants, which leaves them with limited time to recover from stress caused by transplanting. This can stunt their growth and reduce yield. Therefore, choosing the right pot size and type from the beginning is crucial in getting the most out of your autoflowers.
Understanding autoflower pot sizes and their implications can make a significant difference in your growing experience. Whether you’re a beginner or a seasoned grower, the right pot size, type, and growing method can help you maximize your autoflower yield. So, don’t hesitate to experiment and find the combination that works best for your growing conditions and preferences. Happy growing!
