There’s enough of it to go around, but do make sure it does! Any plant, including cannabis, needs fresh air to survive. After all photosynthesis cannot take place without it. This is more important for indoor growers, since outside, nature will provide all the air your plants need. In fact, you can even get too much of a good thing. Always make sure outdoor cannabis plants are safe from gusts of wind by providing some shelter.

Ready – Steady – Grow!

Last but not least, every grower needs patience. It is nearly impossible to speed up the flowering process and ‘cheat nature’. Growing weed at home is a process to enjoy, as you wait for the right time to harvest. If you harvest your plants too early, they might not even have enough THC in them to provide the intended effect. Unless you want to throw in all your hard work for nothing, you’ll have to wait – watching the grass grow, so to speak. Patience is a virtue, though. It gives you time to really have a look at your plants and make sure they are okay – and not being attacked by snails and slugs for example, or falling prey to fungi like bud rot or mildew. It also gives you the opportunity to read our other blogs on growing weed at home.

As you can read in our blog on the various life stages of cannabis, you can draw a basic distinction between three stages in the life of a cannabis plant: germination, vegetation (growth), and flowering. Each of these stages is directed by light, whether indoors or outside. In nature, a freshly germinated seedling first starts to grow as fast as possible to toughen up, with enough leaves to catch the light and firm roots for nutrient absorption. In natural conditions, that happens in spring, when the sun is not yet straight above the equator. As the days get longer, the rays of the sun don’t have their full summer strength yet. Plats ‘sense’ this, so if you get your timing right, your germinated seeds will grow fastest from early May until about mid- or late June. Indoors, you can simulate these springtime conditions all year long by using a ’16/8′ lighting schedule. That means switching on the lights for 16 hours and then switching them off again for eight hours of ‘night’ – similar to outdoor Spring conditions, that is.

A final tip for late bloomers is to pick autoflower seeds. Autoflowering strains pack special genetics that don’t give a toss about how much daylight they receive. That means autoflowers determine their own perfect time to start flowering. Of course, that won’t add a single day to how much summer you have left; but you’ll seriously improve your odds of getting a nice harvest in before the cold sets in.
