Topping, Water Stress & the Root Zone
Each week, High Times Cultivation Editor Nico Escondido brings us three beginner grow tips to help ease the novice cultivator into the art of growing. Today, we cover topping, water stress and the inner-workings of the root zone.
“Topping” plants, or cutting off the top terminal shoot, results in multiple top shoots growing out directly under the cut.
Beginner Grow Tips: This will increase the number of top colas and the overall yield of your plants.
Water stress is the lack of water, or too much water, for a plant. The former results in wilting, with dry, crumbly leaves; whereas the latter causes drooping of moist, heavy, sagging leaves.
Beginner Grow Tips: This stress causes abscisic acid to build up and closes down stomata in leaves, thereby slowing photosynthesis to a crawl.
There is a shift from leaf production to root production during the dark cycle as leaves transfer stored energy down to the root zone.
Beginner Grow Tips: Shut down supplemental CO2 during this time and boost oxygen to the root zone. It’s one piece of advice you’ll be glad that you remembered!
