After rinsing off the dust, I soak s/h pellets in a hefty solution of KLN or super-thrive, 2 tablespoons/gallon. I like to soak for at least a few hours, some advocate overnight to get full hydration, but keep in mind that hormone solutions don't maintain their potency much more than overnight.

I didn't want to buy all those custom s/h pots, so I use a modified method in which I punch extra holes near the bottom of the pots and sit them in trays of water. About once a week, most of the water is evaporated, and I wash the trays and water the pots. That way I can easily add more water to the tray during particularly hot or dry weeks.
Hi Jason, I get the s/h pots because they are not expensive and I usally wait until the solution is not seen in the bottom of the pots. I get almost everything by internet and phone. I am disabled and don't get around much. The pots sit in large waterproof trays. When I water or fertilize I pour until the solution or water reaches the top of the pot. This helps wash out the old solution and entirely wets the Prime Agra. The water contained in the bottom of the trays raises the humidy slightly around the pots. I found out the hard way not to let the roots of newly potted plants quite go alll the way down to the the solution level. When I want to reuse the Prime Agra, I pick out whatever debris I can find. Then I let the pebbles dry and put them in a 350 F oven for about an hour. I let them cool and then they are ready to reuse. Ed
