How do you know your plant needs moved to a bigger pot?

Mines has been planted in a baked beans tin and has been under lights 18/6 for 8 days now.I know it isn't yet ready to move as the pic will show but how long do you usually have to wait until you switch it to a bigger pot?

"how long do you usually have to wait until you switch it to a bigger pot?"

You can transplant at anytime but you should transplant no later than when you need to water it too often. For a cup if I have to water it every day it goes to a new pot. We're concerned about root growth at this stage, clear cups will let you watch your mining operation in action.

The seedling in that picture does not need to be repotted. Do you have holes in the bottom of the can? Very important. When you water soak your pot until water drips from the bottom, then elevate the pot so the water drains. These air pruning cups eliminate root rot in seedlings.

A sure sign is roots coming out of the drainage hole. Assuming that your baked beans tin has one.

Cheers guys,i'll keep an eye on it.

to make sure your not going to worry about the roots just invest into a 5 gallon. most common used and you will 75% never worry about roots

Repot when it has about 2 nodes

pot 1" under the first leafs or even closer cause of ur early strech move the light closer
