cannabis flower cycle from seed

In week 2 of flowering, you may spot the first white pistils growing on your female cannabis plants. These fine and wispy white hairs will develop at those locations where the big fan leaves meet the main stem. It is these fine hairs that will later become buds.

Flowering cannabis plants like daytime temperatures of 20–23°C and nighttime temperatures of around 15–18°C. Make sure to watch out for sudden drops or spikes in temperature when you turn your lights on/off. Sudden drops can shock your plants, while sudden rises can cause condensation to form on the surfaces of your buds, leading to bud rot.

WEEK 5

When the flowering period starts, it isn’t an abrupt change in your plants’ growth. Cannabis won’t just stop growing and then go into flowering right away. In these first weeks of flowering, many cannabis strains may indeed undergo a considerable growth stretch. This is important to know when it comes to feeding your plants properly, but also if you want to give them sufficient space to grow.

Although your plant has officially entered the flowering phase, she will now have an increased need for growing nutrients. You should not abruptly change your nutrient schedule and use flowering nutrients from one day to the next. It is usually recommended that you continue to give growing nutrients for at least one more week once flowering starts.

In the very first weeks of flowering, your cannabis plants will be in the transition stage. Thinking that winter is not far away and that she will soon have to carry a big load of bud, your plant will likely grow rapidly. Some strains can almost double in height during this time. Because of the fast growth that your plant is undergoing now, this early flowering phase is also known as the stretch phase.

Now that you’re familiar with the distinctions between photoperiod and autoflowering strains, we can begin to break down each stage involved in cannabis cultivation.

At this stage, the focus of the grower and plants switches to the production of buds and the grower is already dreaming of a frosty marijuana harvest in the near future. RH needs to be reduced to 40-50% and temps kept between 20-28°C.

PHOTOPERIOD PLANTS

One of the best ways to truly tell if your flowers are ready for harvest is by getting up close and personal with a magnifying device. This visual advantage will enable you to detect minor changes that wouldn’t be noticeable to the naked eye. Some growers choose to use a jeweler’s loupe, which is essentially a pocket-sized magnifying glass encased in a piece of metal. Others choose to use devices such as digital microscopes, which provide greater detail.

Photoperiod strains are induced to bloom by the hours of light they receive; indoors the grower changes to a 12-12 light-dark cycle to artificially promote flower growth.

If you opted to use the dry trimming method, then your flowers will be ready to cure straight away. If you chose wet trimming, then your flowers will need to be properly dried before you go on to cure them.
