I totally agree with all info in the indoor section of this film. About the 1st 3rd.
The Video goes into Greenhouse growing; My specialty. I use many of these methods, and I recommend this section to anyone wanting to grow in a greenhouse.
Outdoor growing section is awesome for those in areas that they can grow outdoors.
Overall; This is one of the most comprehensive Cannabis grow videos that I have ever seen, and agreed with at least 96% of the info.
Learn this. You will be a happy grower.
