Light cycle for seedlings

Done with expert practice and a willing strain of cannabis seeds, it is not unknown to produce 1 gram of ganja per watt of lighting. That’s an impressive 250g in 7-9 weeks for a 250W light in a small cupboard!

Do you want to go from seed to bud quicker and cheaper? A faster, space saving and economical way to grow is the no veg, seed to flower, 12-12 light cycle method.
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.

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 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.
Force flowering marijuana from seed can provide excellent quality, resinous flowers, all the while saving space, time, and money. For those with space constraints, it is a win-win!
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.
There is a lesser demand for resources across the boards.

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.

How to force cannabis to flower from seed for quick, resinous yields using a 12-12 light cycle.

Some seed varieties are very expensive, so low germination rates are simply not an option. Along with keeping the atmospheric conditions consistent (crucial for success in the cloning/seedling stage), choosing the proper horticultural lighting system is imperative. The proper lighting system in this stage will not only help increase success rates, but will also increase the rate at which the plants can be rotated into the subsequent stages.

Inconsistency during early stages of growth can cause a whole slew of problems later down the line. Another disadvantage of HID lighting for the cloning/seedling stage is the immense amount of heat emitted. If not addressed, this heat may be too much for sensitive seedlings or tender clones.
When an indoor horticulturist asks me about ways to improve yields or a garden’s efficiency, I always revert to the garden’s lighting system. Small changes to the lighting system can result in big changes in the garden.

It is a good idea to introduce the plants to a light intensity (per square foot) similar to what they will experience for the rest of the garden cycle. For many indoor horticulturists, this will be 40-50W per square foot of garden space. During this stage of growth, the lighting technology is not as important as the amount of light the plants are receiving. However, consistent light intensity can make a big difference during the early vegetative stage. This is probably the biggest reason T5 fluorescents are so popular for this stage of growth.
One crucial stage of plant development that is often overlooked by horticulturists is the early vegetative stage. The early vegetative stage refers to the stage of growth immediately following the root development of a clone or the period of growth right after the second pair of true leaves appear on a seedling.
Of all the equipment used in an indoor garden, the lighting system is the equipment that should be given the most consideration. After all, the lighting system will directly influence the rate of growth, the health of the plants, and the crop’s final yield.

For example, most indoor gardens consist of multiple rooms for different stages of growth. It is common for indoor horticulturists to have a dedicated cloning/seedling room, a dedicated vegetative room, and a dedicated flowering/fruiting room. Each room will have very different lighting needs depending on the type of crop being grown and the grower’s overall goals.

To have a smooth transition into the vegetative and flowering stages, a foundation must first be built during the cloning/seedling and early vegetative stages. The lighting system used for these initial stages of the plant’s life should be heavily considered. Not only will choosing the correct lighting system be better for the plants, it will also make things easier for the grower. Professional growers still prefer the T5 fluorescent technology when it comes to the early stages of growth.

The lighting system of an indoor garden is the main driving energy behind all plant growth. In other words, if a grower uses an inferior lighting system, he or she will have lower yields and a lower return on investment. Of…
