fast flowering cannabis strains

You haven’t chosen a cannabis strain to grow yet, but already can’t wait to lit that delicious bud? When the temptation is too strong, some strains work better than others. Luckily, Herbies knows what seed to plant if you want to harvest your newly home-grown weed sooner than you can say “fastest-growing marijuana”, the topic we’re covering today. If you’re one of our impatient growers, keep reading to learn about the fastest flowering strains of weed that won’t make you wait for too long.

Fast Growing Weed Seeds: Who Are They For?   

Actually, when it comes to the fastest marijuana strains, their practical application is much wider than the simple goal of getting to smoke the product as soon as possible. The strains we’re about to present have gained recognition because they save growers in plenty of situations.

First of all, if you live in a colder region with a  short summer but still want to benefit from the perks of outdoor growing, fast-growing weed seeds that achieve maturity in 2 months or even less might be your only option to do so. Then, there are stealthy growers who understand that every extra day of having marijuana plants out is another chance of getting caught, so they value the rapid lifecycle. Moreover, the fastest growing weed usually also stays the most compact, which is another pro for a stealthy grower. Finally, these strains allow for not just one but two outdoor harvests in a single season! So, sometimes, it’s not only about the speed but also the productivity of your crop.
