By capillarity. The trough has small perforations that allow the root to pass through, making the root development visible. The seeds are placed in the trough located at the top of the pouch and the water is deposited at the bottom of the pouch. The water moves upwards via the paper wick. Once it reaches the trough, it will moisten the seed.

In most cases, 17 to 20 millimeters should suffice.

It varies. Some seeds will consume the water faster than other seeds. The best criterion is to keep the wick moist at all times. When the wick starts to dry up, add 10 ml. of water.

No, the material is free of any nutrients or chemicals. It is completely inert.

No the ink is made of inert material and will not affect the results of any experiment.

No. The pouch is designed to be used only once. Re-using the pouch will contaminate the media and alter the results.

No, but it should not carry any contaminants.

Yes, the pouch can be autoclaved. The pouch is designed to withstand that process. However, the polypap stand will not withstand autoclave temperatures.

Around two weeks. Usually by the second week the wick will start to break down and mold may appear.

Yes, the trough can be refolded at the second set of perforations to form a larger trough.

By the moistening the trough prior to placing the smaller seeds in the trough, they should remain in place.

The pouch is 7 inches high (18 cm) by 6 1/2 inches wide ( 16.5 cm).

The cost of the aluminum stands increased substantially and was no longer economically feasible.

The stand has 11 slots and we recommend no more than 2 to 3 pouches per slot.

Yes, It is.
