Tuesday’s tips for beginner growers are brought to you by High Times Cultivation Editor Nico Escondido.
1. The goal of CO2 fertilization is to enrich the garden atmosphere from ambient levels of 300-400 PPM to around 1,200 PPM. Do not exceed 1,500 PPM in your CO2 levels, unless you have supercharged indoor lighting of 3,000+ lumens per square foot.
2. When selecting male plants for cannabis breeding projects, height is a primary factor that breeders look for, as well as trichome production near leaf bases and veins.
3. Gardens need lots of fresh air during the dark cycle. This is when oxygen is vital as the roots are using oxygen to grow at night. But the plant is not creating any itself as it “sleeps,” so O2 is at a premium. Turn your intake fans on periodically during the night.
