How to grow the Jack Herer strain (Indoor and outdoor)

As for cultivation, Jack Herer is a reasonably thick and productive plant that produces enormous buds. Make sure that the branches are supported to prevent snapping. The most Sativa plants should be controlled indoors by training or pruning a little. Don't neglect her; she will be quite greedy in fertiliser and will give impressive results in the right growing conditions.

Outdoors, Jack Herer prefers warm, dry climates such as the Mediterranean coast, where she will give outstanding results with large, productive trees. You would be well-advised to use a greenhouse if growing in a cooler, wetter region. In addition, she does not develop a strong odour until after harvest and good ripening; which makes Jack Herer an ally of choice in terms of discretion.
