Tuesday’s tips for beginner growers are brought to you by High Times Cultivation Editor Nico Escondido.
1. Because roots breath and use oxygen to grow, it is best to use breathable pot containers such as fabric bags or smart pots (pictured).
2. Fluorescent lighting is still a popular choice for clone and seedlings nurseries. CFLs or banks of T5 bulbs use little electricity, run very cool and actually provide a broad spectrum for young, developing plants.
3. Yellowing leaves in the last two weeks of flower is a normal occurrence, especially if you are flushing your medium regularly. However, leaves yellowing early on in the flowering stage is a sure sign of a nitrogen (N) deficiency.
