Seedling stage light cycle

Growing with a 12-12 photoperiod is a solution to space and resource problems. This method eliminates the vegetation phase of growth and forces the plant to go straight into flower from a seedling. Yields are lower than that of a regularly grown cannabis plant, but results are obtained much faster, with a few advantages.

12-12 simply refers to the hours of light and darkness a cannabis plant is exposed to – 12 of each. Normally, a cannabis plant is exposed to an 18-6 light cycle. This tells the cannabis plant conditions are good for growth, and it focuses on building up size and foliage. When light cycle is changed to 12-12 (either naturally or through human intervention), it tells the cannabis the seasons are changing, and it is time to flower. By forcing a 12-12 light period from the start, the cannabis plant goes directly into flowering, in a bid to reproduce. You are essentially tricking the plant into thinking the growing season is coming to an end, so it needs to produce flowers ASAP.
Always be sure to re-sterilize your grow space after each crop.

Growing 12-12 is as simple as changing the timing on your light cycles, giving your plants equal amounts of day and night right from when they sprout. The plants will look different to a cannabis plant that goes through vegetative growth. Photosensitive hormones in cannabis make the highest point the largest cola. This method all but guarantees only main bud growth on every small plant. Essentially you will be growing a cola with a few short, budded side branches – with the plant basically being a bud in itself. Be sure to stake your plants.
You will experience only half the water consumption with less moisture loss due to evaporation, and a third less nutrients are used. CO₂ and electricity use including most peripherals are reduced by a staggering 650 grow hours annually.
Keep a keen eye out for moulds and mildews as the grow space will be getting less light with more moulding opportunity in warm dark corners and creases.
Growing this way still requires all the knowledge that would be needed to flower plants with any other method, and maintenance routines still remain unchanged. After diluted nutrients, while still young, treat your plants as you would during a normal bud cycle. However, flush more often, every ten days at most, so as to avoid salt build-up in the smaller pots.
There is a lesser demand for resources across the boards.

There are some haters of this method, but many love it. Those who hate on it often have not actually tried it. It is all about giving it a go and seeing what works for you. Even if you decide against it after trying it, it all helps expand your knowledge as a grower.

Looking for shifts in trichome appearance is the most accurate way to determine the stage of maturity of your crop. Trichomes are hard to miss and appear as a white frosty substance that covers the buds and sugar leaves. Zooming in on these structures will allow you to know how far along your plants are, and whether they are ready for the chop.

The main marker of a photoperiod plant is the potential for indefinite vegetation—as long as you keep the plants on an 18/6–24/0 light/dark cycle. We’ll talk more about that later, but it means these plants can withstand more mistakes in the growing process. It also means you can ensure your plant produces the best crop possible once you initiate flowering. All you need to do to make the switch is adjust the light cycle to 12/12. This becomes even more useful when you’re able to make unlimited clones of your optimised plant. The main drawback is that it’ll take around four months to get a substantial yield. However, you’ll have a larger and usually more potent plant once you’re there.
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.

Before you just start throwing seeds into soil, consider what kind of grower you want to be. Are you running an indoor operation, or working in the great outdoors? Do you have the supplies fit for your growing environment? Have you made sure to pick seeds that’ll thrive where you’re planting them, indoors or out? Speaking on that last point, any aspiring grower should know the difference between photoperiod and autoflowering cannabis plants. There are a few key differences to note.
Growing cannabis comes with a lot of uncertainties. That said, cannabis cultivation itself can be broken down into five distinct stages, regardless of which seeds you’ve selected.
If you see “nanners” or anything resembling a cluster of grapes protruding from flowers or anywhere on the stem then you have a male cannabis plant. Should you see both hairs and nanners then you have a hermie to remove right away.
Now that you know when to start harvesting your buds, it’s time to learn how to trim them.
Now that harvesting and trimming are complete, it’s time to cure your flowers. Curing is an essential process that removes the last of the residual water from the buds, minimising the chance of mould and greatly prolonging shelf life. Curing also enhances the taste and quality of the smoke, making for a smooth and potent experience.

Harvesting is the most rewarding part of the cultivation process for many growers. Watching your plants grow over several months is mesmerising, but finally harvesting the fruits of your labour truly is the peak of the experience. The flowering phase of the grow cycle typically lasts between 7–11 weeks, after which it’s time to strip your plants down of their buds. However, you don’t want to do this too early and prevent your flowers from fully maturing. Likewise, you don’t want to wait too long. Timing harvest is a crucial step, and there are multiple signs you should look out for to know when the time is right.

From germination to curing, understanding each stage of the cannabis growth cycle is vital to achieving a healthy cannabis crop.
