Three Steps to Effective Greenhouse Humidity Control

This graphic shows how net water vapor is removed when one uses ventilation as a means of dehumidification. The continuous cycle of removing net water vapor and adding heat during ventilation makes it an energy-intensive method of dehumidification. The best defense against fungal infection for high-value, susceptible greenhouse crops is to create environmental conditions that …

Effect of Transpiration on Plant Accumulation and Translocation of PPCP/EDCs

Abstract he reuse of treated wastewater for agricultural irrigation in arid and hot climates where plant transpiration is high may affect plant accumulation of pharmaceutical and personal care products (PPCPs) and endocrine disrupting chemicals (EDCs). In this study, carrot, lettuce, and tomato plants were grown in solution containing 16 PPCP/EDCs in either a cool-humid or …

Advanced Aeroponic Cloning — THE SECRETS!

This article is about those methods that produce clones covered with roots from collars to cut…and with no loss of growth potential or yellowing above the collars. As always, I keep efficiency and scaled production in mind! Water Temperature. In cloning, warmer temperature speed cell divisions with diminishing returns at 87 °F (30 °C). However, this …
