How to Transplant Your Seedling for a Healthy Start
05/01/2025
So, your seedling has made it home—and judging by those roots, it’s transplant time! Transplanting cannabis seedlings doesn’t have to be stressful for you or your plants. Here’s a step-by-step seedling transplanting guide to ensure a smooth transition.
When Is a Seedling Ready to Transplant?
Your seedling is ready for transplant when:
- It has a strong, healthy root system
- Several true leaves have formed
- It’s outgrowing its current container (like a solo cup)
Preparing to Transplant your Cannabis Seedling
To give your plant the best chance at success, follow the tips below.
- Match moisture levels: The soil in the new pot should be as moist as the seedling’s current medium. Aim for damp—not soaking wet or bone dry. Keep in mind you may want to very lightly water after transplanting.
- Choose the right pot size: For photoperiod plants, size up gradually. A solo cup-sized seedling should move to a 1- to 2-gallon container.
- Prep the new container: Lightly pack soil into the bottom and sides of your new pot, leaving enough space to completely cover the root ball.
How to Transplant Your Seedling
- Carefully remove the seedling from its current container, keeping the root ball intact.
- Place it in the new pot so that the top of the root ball sits ½ to 1 inch below the surface of the soil.
- Gently fill in around the root ball with soil, and lightly press down to secure it.
- If your seedling has started to stretch (get tall and leggy), you can bury part of the stem to help stabilize it.
Final Tips for a Successful Transplant
- Water lightly after transplanting to help the roots settle.
- Avoid fertilizing immediately—give your plant a few days to adjust.
- Keep it in a gentle light environment for the first 24–48 hours to reduce transplant shock.
Follow the easy tips in this seedling transplant guide and your seedling will be well on its way to becoming a strong, healthy plant!
