Grower’s Tip:
• Not enough oxygen at the root zone is the leading cause of root death — ROOTS NEED OXYGEN!
• Plants should NEVER sit in stagnant nutrient solution — ensure proper drainage by tilting growing trays.
• Organic matter in your nutrient solution and trays can reduce oxygen levels — KEEP IT CLEAN!
• Always provide plenty of oxygen — plants should NOT have to compete for oxygen.
• High temperatures reduce a solutions ability to “carry” oxygen while increasing a plants need for oxygen.
