An inexpensive rooting box.
Inexpensive Root starter box
To create a good environment for rooting cuttings you need good light and control of humidity until the roots can support the needs of the new plant
PETE Grow box
An inexpensive rooting grow box can be created by using clear PETE, vacuum molded, salad containers.
To the left you will see a drawing that demonstrates the concept of removing enough of the flange of one container to set the top one into the bottom containers’ flange.
I remove the flange in two passes as the convolutions make it difficult to get a good job done in one pass. Remember to remove only the amount needed to set one into the other as the remaining flange stiffens the edge.
PETE container labels
The first thing to do is remove the labels from the container that you will be using for the top. Important! do this as soon as possible. A dry, new label peels cleanly off easily. Just lift the edge and peel slowly, use a sharp knife to assist with sticky spots. A wet or old label is very difficult to remove. Use that container for the bottom! 😦 PETE is resistant to most solvents if you really do need to clean up old glue.
Top flange fit into lower flange
If the shape and cutting is correct the top will fit into the lower tray flange. This will preserve a high humidity environment for the cuttings while they force roots to form. The clear PETE transmits a maximum amount of light so that the cuttings can make sugar to feed themselves. And you can see any water in the base. Be sure to open the box from time to time and talk to your new babies. they don’t care what you have to say. But they do appreciate the CO2. 😎 pg
Important note: store out of the summer sun! A dry empty clear PETE container will warp badly if left in hot direct sun. Even in the Green House. pg
