Buying and growing marijuana seeds in the USA

The USA has undergone a cannabis revolution. The country’s legal weed-growing industry is the best in the world. Within this new and open climate, there’s never been a better time to grow at home.

By growing your strains exactly as you like them, you know exactly where you’re getting them. No additives, no middlemen, just pure, unadulterated cannabis.

While some states have some catching up to do when it comes to home-growing laws, you can still avoid the expense of dispensaries by setting up a home-grow setup. Popular American autoflower strains, among other fantastic varieties, are easy to grow across the USA. If your climate isn’t as favorable as sunny California, no worries; just take it indoors.

Growing

OG Kush is a diverse and alluring plant that’s perfect for experienced hobbyists. Easy to grow, it still requires some experience to master its flowering stage and reap greater yields.

Chemdawg is a highly potent OG strain that’s earned a permanent place on the US cannabis hall of fame. Related to legends like OG Kush and Sour Diesel, it’s its own distinct thing, with lashings of diesel.

Growing

Chemdawg is best suited for advanced growers and hobbyists, thanks to its adaptability to SOG and SCROG techniques. Growing out like a Christmas tree, it doesn’t do well outdoors. That’s because of its susceptibility to mold and the need for pruning care. Take it indoors or to a greenhouse/tent setup, and you’ll control every inch of its growth.

While suited for outdoor growth too, it is very picky about its climate, requiring warm, dry weather and prolonged periods of sunshine. Think areas around California, Nevada and Colorado.

In other parts of the USA, you’ll get excellent results in a greenhouse, where you can expect big yields with added shelter and control.
