Garden & Greenhouse Product Review - The O2 Grow Unit http://gardenandgreenhouse.net/index.php/products-mainmenu-22/108-product-profiles/2078-garden-greenhouse-product-review-the-o2-grow-unit Anybody here using this new oxygen technology in RDWC DWC pot grows today? If so, how’s this working for you. Type A grower prevents fungal outbreaks. Type B grower’s waits patiently for the root rot and just accepts it, then treat the disease outbreak when symptoms present? Many/most RDWC DWC pot growers practice crisis intervention (treatment with chemicals) routinely when it comes to fungi and root rot diseases. It’s common and customary to wait till symptoms appear, brown slime fungus on the roots, you know the symptoms and the routine… the race is on to save the crop. Waiting and watching for the rot symptoms causes some growers a little angst, other growers know it’s coming and have the chemicals and teas on standby ready to roll, these are the growers that prefer to treat the disease vs. prevent the disease Growers always have a choice, the treatment or prevention. “They” say that Pythium and other fungal pathogens are opportunist, they are ubiquitous and wait patiently for the right opportunity in nutrient solutions and root zones. “They” also say that the right opportunity is a “low oxygen” event. “They” also say that preventing a “low oxygen” prevents any opportunity for a fungal disease outbreak.
