The Art of Transplanting: Ensuring Success for Your Young Hemp Plants

 

Mastering the art of transplanting is crucial for ensuring the health, vigor, and productivity of your plants. With BudTrainer's expert guidance and our user-friendly gardening accessories, you'll learn the proper techniques and timing for transplanting, allowing your young cannabis plants to thrive in their new environment.

1. Tools & Materials

  • Enriched soil

  • BudCups (from when you planted your seeds)

  • BudPots (see size chart at the bottom)

  • Dechlorinated tap water

   

2. When is it time to transplant my plants?

The timing of transplant doesn't go by a set number of days. Some marijuana plants will grow vigorously and be ready for it in 3 weeks, while others can get stunted and take more than 6 weeks to be ready. The tell-tale sign that your plant is ready for transplanting is whether it has roots at the top of the rootball. Whenever roots form at the top, this means that they will "shoot out" into all directions after you transplant, which is exactly what we want for proper root formation.

To peek at your roots, simply pop the bottom of the BudCups and have a peek at your roots!

How to select the right size of pot for you

Pots, like the BudPots, come in various sizes ranging from 3Ga to 100+Ga. The question is, which one is for you? There are a few things to consider, and they are broken down below:

BudPots 3Ga

For short-cycle plants, like short flowering period autoflowers or photoperiodic plants that will be flowered within 6 weeks of sprouting.

Great choice for indoor growing, but too small for outdoors. 

BudPots 5Ga

For short-ish-cycle plants, like long flowering period autoflowers or photoperiodic plants that will be flowered within 8 weeks of sprouting.

Great choice for indoor growing, but too small for outdoors. 

BudPots 7Ga

For medium-cycle plants, like long cycle autoflowers or photoperiodic plants that will be flowered within 10 weeks of sprouting.

Great choice for indoor growing, and can also be used for outdoors on fast-flowering photoperiod strains. 

BudPots 10Ga

For medium-to-long-cycle plants, like photoperiodic plants that will be flowered within 12 weeks of sprouting.

Great choice for outdoor growing, but too large for indoors (except for living soils).

BudPots 15Ga

For long-cycle plants, like photoperiodic plants that will be flowered within 15 weeks of sprouting.

Great choice for outdoor growing, but too large for indoors (except for living soils).

BudPots 25Ga

For long-cycle plants, like photoperiodic plants that will be flowered within more than 15 weeks of sprouting.

Great choice for outdoor growing, but too large for indoors (except for living soils).

3. How to Transplant Young Weed Plants 

  

Step 1 - Fill your BudPots with soil

In order to transplant your cannabis plant, first you will need to fill up your BudPot with soil. This part is super easy - go ahead and dump the soil inside your BudPot until the final 1 inch from the top - just be careful not to make a mess!

Step 2 - Make a hole

In order to plant that young marijuana plant into the soil you need a hole the same size as the BudCups (or other plastic container). For this, you can start from the center and slowly dig a hole in the soil by pulling it to the sides with your hands. Once the hole is about the size of the BudCups, it is ready for transplant.

Step 3 - Transplant your plants

Now that you have a perfect hole for the BudCups (or other plastic container), it is time to remove your young plants from them and transplant your rootball into the soil. For this, simply pop the bottom of the BudCups with your finger until the entire rootball comes out. If the bottom plate is still stuck to the bottom of the roots, make sure to remove it before transplanting.

As you do this, pull on the young plant's stem to see if it is strong enough to hold the entire rootball. If it is not, pick your plant up from the sides of the root ball, but very gently. Be careful not to hurt your baby plant during this transplant!

After your rootball is out, now you just need to drop the rootball right inside that perfectly matched hole, and shake your BudPots to allow the soil to fall around the rootball. Make sure that the soil on your BudPots is nice and flat, but do not press down on the soil as this will make it more difficult for your roots to grow. Just a little shake is all you need!

 

Upgrade Your Craft: Use Mycorrhizal Fungi

Mycorrhizal fungi is a commonly used supplement for weed plants as it helps your roots intake more nutrients, thus allowing you to grow bigger plants. This fungi creates a mutualistic relationship with your roots, where it absorbs more nutrients from the soil in exchange for some sugars from your plant. Working together, they create massive root structures that take your plants to the next level.

Just use one teaspoon of mycorrhizae at the bottom of your BudCup hole, and then insert the rootball into the same hole, and shake the BudPots in order to let the dirt fill in the gaps.

Once the rootball is in, sprinkle another teaspoon of mycorrhizae around your plant's main stem. Cover it with a little bit of soil, and make sure that the top surface is nice and flat, but do not push down on the soil as it will inhibit your roots from growing (roots like mini air pockets to grow into, not a dense and compressed soil).

   

Step 4 - Water your soil

Using¬†2 liters (¬Ĺ gallon) of dechlorinated tap water,¬†moisten¬†the soil¬†slowly (ideally, over 60 seconds). There should be no water coming out at the bottom (or you are watering too fast). This will be enough water to keep your¬†plant going for another week without watering.

Step 5 - Wash your BudCups & reuse

If you are using the BudCups, give them a rinse to remove the excess soil, scrub them with a soft sponge or brush, and if you don't want to wash them by hand, just toss them in the dishwasher!

FAQ: What if I am transplanting in the ground?

If you plan on planting directly into the ground, you can follow the same steps outlined in this lesson, but you may skip Step 1. Just be careful not to overwater your plants in the ground, as it can hold onto a lot of water! Also make sure that you are feeding your plants the correct nutrients - the advantage of growing in the ground is that it is very difficult to over feed nutrients, as they dissipate around quite easily. Also ensure that your soil is not heavy on clay (it needs lots of air pockets for roots to grow).
