In my absence, I finished a double-degree in Botany and Environmental Science. This and most other weed forums are based on incorrect information, myths, fallacies, half-truths and flat out lies. if you want to grow better plants in-general, don't listen to any advice your given on a forum like this.
There are professional hemp and plant science researchers who scour sites like this and laugh hysterically at some of the posts and are often used in explaining spreads of misinformation as it relates to agriculture. Many of the posts I have read, my own included, are all nonsensical and everyone here is wasting their time.
