Buoyancy Comparison

Capillarity Test - Wicking Ability

All four pots were filled with an equal volume of water, enough media to cover the water, and topped with dry media; ensuring that only dry media came in contact with the wet media in the reservoir at approximatly the same level.  The initail level was then marked on the pots.

30 minutes into the test and here was notable capillary action on all but the TWFKI medium so it was removed from the test.

Note that HygroStone_^® has kept up with both versions of PrimeAgra_^®.

Compare HygroStone_^® to the original PrimeAgra_^®, and you can see how similar they perform.
