can you plant a cannabis seed in the big pot

Stretchy or floppy seedling growth can be due to genetics. Often, it’s an indication the grow lamp is positioned too far away from the canopy. A cool white 250W CFL can comfortably hang 15cm above a dozen or more seedlings without scorching leaves.

Next, make an impression in your large container with another small pot, or the one with the plant in it if you don’t have any others. Make this impression in the medium after you have watered it. This creates a perfect imprint for the transplant.

THE OPTIMAL CONDITIONS FOR SEEDLINGS

Cannabis seedlings need to be treated delicately. Mind your marijuana like babies. If seedlings need support, prop them up with a toothpick or a cocktail stick and some soft gardening wire.

Rockwool cubes and blocks are made for hydroponic growers. Start your seedling in a small cube and it couldn’t be easier to transplant later. Simply cut a cube-sized chunk out of a larger block and insert. The process can be repeated with minimal stress to plants.

Cubes are the easiest to work with. Either cut a hole to size in a bigger block, or burrow a hole into the medium with your fingers and insert for a snug fit. Potting up takes a little more finesse. First, don’t fill your large container all the way to the top. Leave room so you can water properly later. If you pack the pot all the way to the top, water will mostly run off and not reach the roots.

Roots will also want adequate aeration and oxygen. When the roots have easy access to oxygen, this not only promotes fast growth, but will also help keeping mould and other growing troubles in check. A stale root zone depleted of oxygen will almost always lead to problems, if not entirely kill off your plants.

If you visit a grow store or search around online to get some pots on the internet, you can find various types of containers for cannabis growing. Here are some of the most common types of growing pots.

Another more advanced solution can be with an automated pump, that can take care of the runoff water, that will collect in your tray.

Some types of growing containers like smart pots or air pots will require much bigger saucers, since excess water will flow down the sides when watering. Take this into account.

Hempy buckets are providing a type of manual hydroponic system for growing cannabis plants. The difference to normal pots is, that the drainage hole isn’t at the bottom, but several centimetres above, which leaves a small reservoir of nutrient solution at the bottom of the hempy bucket.

This is for when you’ve just planted your cannabis seeds or clones in a too-big container. By giving your young plants less water at a time following the steps below, you prevent overwatering which can slow down seedling or clone growth in a too-big container.

Transplanting will provide your plants with faster growth if done right. This is because transplanting allows you to set up an environment where your roots are getting access to plenty of water and air. However, transplanting can stress your plants (and slow down growth) if not done properly. When transplanting, it’s important to carefully move plants so that their roots are not disrupted in any way. This means moving plants before they get root-bound, and creating a hole in the potting mix of their new container so the plants can be placed right in without disturbing the roots.

If you plan on starting your plants in a small solo cup and transplanting your plants to bigger containers as needed, take a look at this transplanting guide.

Summary: How to water cannabis seedlings or clones in a too-big container

Sometimes you want to start your cannabis seeds or clones directly in their final container. This saves time transplanting from smaller containers to big ones. However, when seedlings are growing in a big pot, you need to make sure you’re watering plants properly. Read on to learn exactly what to do.

Important: Always wait until the top inch (up to your first knuckle) is starting to feel dry to the touch before watering your plant again. This prevents both overwatering and fungus gnats 🙂

Don’t give water again until the top inch of potting mix is dry to the touch (which should be less than a few days if you did your job right). This makes sure your seedlings get a perfect mix of air and water so it grows as fast as possible.

Small seedlings can’t drink more water than this!
