1 gallon cannabis grow

Take whatever i say with a grain of salt though, i am just going by memory.

Most will say no way, but I will post some pics of my monsters.


like the title says im curious to see what my fellow canagraphers can yiled using only a 1 gallon pot?

I dont care what medium, what type of system i just want to know how much you guys have pulled or averaged using only a 1 gallon containment system per plant.


The problem with running small pots if your running something like a DWC is keeping it filled. I’m running 2 gallon DWCs right now and I’m about six weeks into flowering now, the plants are drinking the nearly the entire res every day. Before this grow I grew in a 3 gallon DWC and that I think was the optimal size.

1 gallon cannabis grow

3 gallon pots tend to be the most commonly used pots, these offer a good balance between pot size and room to grow – your cannabis roots should have adequate enough room for a decent grow, whilst the pot doesn’t take up too much room in your grow room, allowing you to grow more plants in a restricted space.

Make sure to thoroughly clean you pots before bringing them into your grow space, there may be chemical residue or other impurities left over from the shop or factory. It is also important to only put one plant in each pot, no matter what the pot size is. This will stop any need for competition between plants as well as make sure that any problems that may occur are isolated – should the soil in one pot accidentally build up toxic levels of nutrients, it will only affect one plant.

So what is ideal pot size for a cannabis plant?

Choosing a plant pot is an important but often overlooked task. They come in all shapes and sizes that are all going to effect the way your plant grows in some subtle way.

It is best to keep your cannabis plants in pots varying between 1.5 – 3 gallons, 3 gallons being the norm (1 gallon is 3.8 liters). If you have a lot of room in your grow space then you may even want to consider 5 gallon pots.

Different pot sizes

As you can see, the size of your plant pot can have a large impact on how your plants grow. It is most important to make sure your roots have enough room to develop and grow, otherwise you may find that you have a stunted plant. Giving your plant more room than it needs can let it really flourish. However, you must bear in mind, whilst having too little room will definitely negatively impact your plant, having loads of room is not going to get you extra results unless other, more important factors such as light and nutrients are at optimal levels.
