In addition to being one of these popular home grown marijuana strains, Jack Herer is arguably one of the most popular and best strains in the industry. This particular strain is great for beginners because Jack Herer requires a fairly effortless growing process. Jack Herer is also a heavy yielding plant, so with little effort, growers will produce plenty of flowers. Purple Kush is another popular home grown strain that is slightly more challenging to grow, yet it thrives in both indoors and outdoors. These distinct, dense purple buds produce flowers with THC levels as high as 27%.
