Provide a drainage system for the plant stand/ upright pipe, so that the plants in the fabric pots won't be submerged in water. I can drain the water later on.

It is also very suitable for measuring nutrient runoff.

3.5-inch pots are best suited for planting one seedling each, or they can be placed in small seedling trays

7.5 inches is the most suitable size for a 1-gallon pot.

8.5-inch and 9.5-inch are most suitable for 3-gallon pots and larger drainage trays.

Scale on demand!

The newer version has a slightly cooler central support.
