CANNAtalk - Issue 14 2011

We just received in both stores the new issue of CANNAtalk, the magazine put out by Canna Nutrients (it is not primarily about their nutrients, it has great articles on the science behind growing and useful info on growing in general, as well as some more in depth advice in regard to the use of their products). I always get asked why plants in the flowering stage need red light as opposed to blue light, and there's an article written by Geary Coogler (BSc Horticulture) that goes into scientific detail as to why (in short, it triggers flower production, but read the article to see why, how and what else it does). There's also a good Grower's Tip as to when and why to change out your bulbs.
