Want to start growing weed but not sure which nutrients to get?
One of the easiest, most reliable, and cheapest nutrient systems that work great for growing weed is the General Hydroponics Flora Series.
The General Hydroponics Flora nutrient series is easy-to-find at any hydroponics shop, most gardening stores, and definitely can be found online.

A good place to start is at half of their recommended doses.
But if you don't want to figure it out for yourself, I've created a guide specifically for growing marijuana with this nutrient system..
