How to grow cannabis plant.Step by step tutorial pt 8

---

The growth of a cannabis plant from amsterdam weed seeds depends on the number of hours of light it gets each day. The more hours light, the stronger the plant will grow. The mostused light period in cannabis growing is 18 hours light per day and 6 hours night. This corresponds to the 21st June, the longest day of the year, and a sunny one at that.

We kid the plant that it is the always the most lovely and longest day of the year. But you can just as well give your plants 19 hours, 20 hours - right up to 24 hours light per day. With a 24-hour light period your lamps are burning continuously, of course. But if you give the plants less than 18 hours light you increase the chance that the plant will start to bloom. Some amsterdam weed seeds varieties bloom when given 15-16 hours light. Whenever we talk about “putting the plant into bloom” we are referring to the practice of putting the lamps on a timer set for 12 hours light and 12 hours night. This is the optimal period for blooming. If you give her more hours dark, then the plant will come in to bloom more quickly, but the yield will be less, because you have convinced her that winter is just around the corner. This is sometimes worth doing at the end of your bloom period to tip the plants into a ‘harvest-ready’ state a little earlier.Why just 12 hours? Because the plant needs light in order to develop its buds and make its THC. The more light, the more bud growth and THC production. The perfect boundary therefore is 12 hours, so that the plant can bloom well, while developing a good, THC-rich bud with a decent yield as it does so.

Now I can hear you thinking: ‘then I’ll just give the plant even more light!’ But this will simply prolong the blooming period without adding anything to the size or potency of your crop. The length of the blooming period is dependent on the plant weed seeds variety and can be anywhere between 5-16 weeks. The most common varieties though all bloom after 8-10 weeks.
