a different pot for each stage.step by step to potting up.

Potting up is the process of growing a plant in a smaller container and increasing the size in stages, rather then planting directly into the final container, as this can slow down growth and increase the risk of pests and diseases. Most growers re-pot their plants after about two weeks into the 5-6 inch (125-150mm) pots. Next, when the roots have completely filled that 3 liters minimum but 11 liters is typical (6 liters for auto flowering strains). Use plastic containers rather then wood, metal, stones, or ceramic ones as they can contaminate the medium. When potting up to your final size in a soil grow, use square pots rather then round ones as they are more space efficient. Anytime a plant is re-potted is causes stress, which can stunt growth for a few days, so don’t re-pot once flowering has started. Similarly, owning to the short life off auto flowering strains, it’s best to go straight from the starter container to the final size pot size.

To replant your seedlings you will need the following:

You will need:

For soil:

  • 5-6 inch (125-150mm) pot
  • Soil and perlite
  • Gravel or clay pebbles

For hydro:

  • 5-6 inch (125-150mm) net pots and clay pebbles or alternative is Rockwool cubes

1) When the seedlings is approximately 4 inch (10 cm) tall with several leaves and plentiful root growth spreading to the edges of the pot, it is ready to be potted up.

2) If growing in soil add a layer of gravel or clay pebbles to the bottom of your new pot aid drainage. Fill the rest with a mixture of one part perlite to three parts soil, gently pack it down, and water. Make a hole in the soil big enough to fit the small pot inside. Some growers choose to add a root stimulant to the hole at this stage .

3) Gently squeeze and tap the small pot containing the seedlings so as to loosen the soil from the pot. Then place your hand on top of the soil with seedlings stem protruding between your middle and fourth fingers.

4) carefully turn the plant upside down so it is balanced on the hand holding it, and use the other hand to remove the pot.

5) Now cup the soil and root-mass in both hands, trying to prevent it from breaking apart, and lower it into the whole. Add any extra soil around it to fill the hole, gently pack it down, and tap the sides of the pot so that all the soil settles down inside.

6) If growing in rockwool cubes you should be able to insert the smaller cube into the pre-cut hole of the larger one.

7) If using a net pots of clan pebbles, place the small pot inside the larger one, ensuring there is a layer of pebbles around all sides of the small pot, including above and below.

Changing pots is a very important part off the process. Experience growers change there pots in stages this way the roots expand and also can improve final yields.

It is an option for some growers to place there seeds straight into a large pot which a lot off growers would end there potting up process on, what this will do is not allow the roots to absorb all the moisture. It is best to start your seedlings in a small pot or preferably a plastic cup (make sure its not a clear one) this can then lead too a 2.5/3 litre pot and then your final pot after or can skip it and go straight to the large final pot.

Growing in containers allows limitations for plants development with root expansion. Roots need to expand to make sure the plants grow healthy and flourish. By controlling your pot sizes you limit the amount of space that’s there for roots to grow, and this is a crucial part off the process in order for the plants to reach its full potential.
