Two seasons back a grower I work with called me in a mild panic. His cucumber crop was yellowing between the veins, the classic iron signature, and he had a bottle of chelated iron and a two-litre hand sprayer. He misted the whole house…
A grow tent running a recirculating deep water culture loop is not a bucket with a bubbler dropped in it. It is a small closed system where every number leans on the next one. Water temperature sets the oxygen ceiling. The oxygen level…
I have worn out three fertilizer injectors in nine years. Two failed the same way: a hardened O-ring in the water motor, a ratio that crept without anyone noticing, and a fortnight of lettuce fed on something closer to tap water than…
pH is the number growers watch hardest and understand least. A reservoir holding 5.9 can sit steady for a week. The same tank drifting to 4.7 will bruise roots while the EC meter reports nothing wrong. The gap looks small on paper. In a…
Growing healthy plants starts with understanding one of the most important factors in plant development: light. Whether you’re cultivating herbs
Electrical conductivity, or EC, is the first number most hydroponic growers learn and the last one they learn to trust. It measures how well a nutrient solution carries an electrical current. Dissolved nutrient salts sit in water as…
Maintaining the correct pH level is one of the most important responsibilities in hydroponic gardening. Even the most carefully balanced
For many gardeners, hydroponics seems like the next logical step after years of growing in soil. The promise of faster
Algae shows up in nearly every hydroponic system I walk through. Rosa Raudales, a University of Connecticut researcher, reports algae accumulation in almost every hydroponic operation she visits, with deep-flow raft systems hit hardest…
Growing plants hydroponically offers incredible control over nutrients, water usage, and plant health. However, one factor can quickly turn a
