Nothing beats compost for improving soil for your garden. That’s how Mother Nature intended it, but we have some options to give her a hand in decomposing yard and garden debris in a more speedy fashion!


Ebb and Flow hydroponics uses a tray to hold your plants above a reservoir of nutrient solution. The tray holds the pots filled with growing medium. At regular intervals, a timer starts the pump so it fills the tray with the nutrient solution, then drains back down into the reservoir.
This keeps the plant roots regularly drenched with nutrient and air, both essential to healthy plant growth.
