12 12 light cycle from seed led weed grow video

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.

Plants with less side branching and canopy spread need less space between them, increasing efficiency. As an example: 1x 15-litre pot produces one plant with a large volume and difficult maintenance issues in a cramped space. 4x 3.5-litre pots in the same sized space can produce just as much dried material with the benefit of being easier to rotate, so the whole plant gets 360-degree light. The entire crop is less hassle during maintenance as each plant is 100% accessible and physically easier to move about. There is no need for a separate sprouting and veg space or time wasted on 18-6 vegetation. The seeds can be sprouted under the 12-12 growing lights providing continual flowering plants.

There is a lesser demand for resources across the boards.
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.
Taking hours to accomplish, tipping, fimming, branch control, and mainlining are now unnecessary freeing up your most precious resource, time.

CLEANLINESS

The 12-12 lighting technique makes the grow cycle 7-9 weeks in general, rather than the much longer time needed when giving plants a vegetative phase. For the space constrained, and those willing to experiment and give it ago, it can be a dream come true.

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.

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.

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.

Once your light intensity has reached the level you want for flower and your plants are happy, let them do their thing! At this stage, you can adjust other environmental variables as needed. Keep in mind that any cultivation changes can impact plant performance as you transition your crop through its life stages. Try to minimize the number of changes you make at any one time to maintain your crop’s health.

For the first 1-2 days in flowering, just let your plants get used to the new 12-hour photoperiod. Leave light intensity the same as what they were exposed to in the vegetative stage.

After the plants are acclimated to their new photoperiod, you can begin gradually increasing light intensity by about 10% every 1-2 days.

STEP 2: Begin to Increase Light Intensity

Many growers run into issues when flipping their veg room to flower. Keep your crop healthy and avoid shock damage by gradually transitioning your plants from their vegetative to flowering lighting conditions. Do this by incrementally increasing light levels and limiting cultivation changes to as few variables as possible.

If your LEDs are integrated with a lighting control software like smartPAR™, you can program your lights to increase intensity incrementally until you reach your maximum flower light intensity.

Your cannabis crop is looking great as it completes the vegetative stage – uniform structure, robust size, pest and pathogen-free. Now it’s time to switch from veg to flower!

Signs of stress can manifest as leaf drop, chlorosis (yellowing) of leaves, reddening of leaves, drooping leaves and slow growth. If your crop is showing signs of stress while you make the transition to higher light intensities, lower the light intensity and make more frequent lower intensity increases to complete the transition.
