# Transplanting

> Transplanting moves a plant and its root ball into a new container or the ground; done gently it causes little shock, but GenetixBay advises against it for autoflowers.

Transplanting is moving a plant, with its root ball, from one container or site to another. The aim is more root room without breaking roots. Transplant shock is the pause in growth that follows when roots are damaged, dried out or exposed to a sudden change of medium, temperature or light.

## In practice

Water the plant a few hours beforehand so the root ball holds together, pre-moisten the new medium, set the plant at the same depth (or slightly deeper for leggy [seedlings](https://genetixbay.com/knowledge/glossary/seedling.md)), and keep light a little gentler for a day or two. Transplant when roots reach the walls but before they circle.

For [photoperiod plants](https://genetixbay.com/knowledge/glossary/photoperiod.md), a careful transplant costs very little. For [autoflowers](https://genetixbay.com/knowledge/glossary/autoflower.md) it is a different story.

## Don't confuse with

- **Up-potting**: one specific kind of transplant, into a larger pot of the same medium.
- **Hardening off**: [acclimatising](https://genetixbay.com/knowledge/glossary/hardening-off.md) a plant to outdoor conditions; often done before an outdoor transplant, but a different step.

## Myth check

House position (grower practice): for autoflowers, transplanting is almost a no-no. Autos run on a fixed countdown from [germination](https://genetixbay.com/knowledge/glossary/germination.md), so any setback costs time they cannot make up, and in the founder's experience their [taproot](https://genetixbay.com/knowledge/glossary/taproot.md) reacts worse to disturbance than a photoperiod's. Sow autos straight into the final pot.
