It allows the hydroponic hobbyist to maintain proper nutrient balance and to achieve optimum growing conditions in soilless cultures. Reagents sufficient for 50 tests per factor and complete labware are foam-mounted in a sturdy carrying case. Instructions and 75-page hydroponics handbook are supplied. |
