Ever heard of light deprivation greenhouses? These masterful modern powerhouses harness the forces of nature, bringing you the highest quality lucrative flowering crops on the market today. 

But before you invest in one for your business (or hobby), maybe you want to fully acquaint yourself with how these systems work. 

Sure, these setups have substantial costs to begin with. But how do you really know if they’re worth it? Will they work for you and your unique business? Are they a good fit for the operation you want to run?

The answer: yes! 

However, one of the best ways to understand why they’re truly a smart choice is to read up on the simple science behind them.


Light deprivation greenhouses are wonders to behold. They give you control over elements of nature that other growers don’t have, and get you the best flowers possible – all while being very sustainable in the process.

How is this possible? Well, it all has to do with the science and biology of the plants themselves. As they say: science never lies!

With that said, let’s take a look at how light deprivation systems successfully tap into science and biology – all to successfully bring you an unfailing, reliable, and wonderfully simple system and a unique competitive edge.


If you haven’t brushed up on your plant biology for a while, here’s a simple starting point: plants flower solely for the purpose of reproduction. 

Depending on the species, flowering happens at certain times of the year. These times in turn depend on the reproductive benefits each species is seeking: seed stratification, pollinators, consumption, transportation, and more. 

For a lot of plants – though not all – the time to flower is especially pivotal before the end of summer, just as fall is coming on. Such species use all the warm or hot months to put out more foliage and leaves, expanding their size and surface area to absorb as much food through photosynthesis as possible.

Root structures and systems are similarly built up and expanded during this time, all for storing this food as energy for future use – particularly to last through winter.

However, most types of flora inevitably need this energy for yet another important function, and one that takes place long before temperature drops and killing frosts arrive: flowering and reproduction!


Sometime before winter, plants must make sure that they reproduce. Flowering, pollination, and seed development are all major tasks on their biological checklists.

If they don’t do it before winter, the energy they’ve worked so hard to collect goes towards basic survival and food stores instead. 

Cold weather is also an endangering factor for seeds and offspring. If seeds don’t have enough time to fully develop before their botanical parents go dormant, they may be rendered lifeless, or the life within them killed by the frost. 

If plants miss the boat this way, this is bad news! They lose the chance of guaranteeing their species’ population growth the year to follow. They also fail to pass their genetics on to future generations of their kind.

As with any species, reproduction is not something to be missed. Luckily, plants have some very clever triggers they depend on to guarantee that it occurs, no matter what.

Like the article stated earlier, some tend to flower at the end of summer, knowing that this is their very last chance to spread their seed. Others, however, may flower at the very beginning of spring, midsummer, and so on.

Regardless of the time of year, how do they know when to flower at such important, specific times? 

By tracking the light cycles of the seasons, pure and simple.


When you get down to it, plants aren’t all that different from us. Believe it or not, human beings also depend on light cycles to govern certain bodily functions – a function known as the circadian rhythm.

For us, it helps shape metabolism, appetite, hormonal shifts, sleep patterns, and more. Like plants, too, it’s triggered by patterns of light and darkness.

As it turns out, flowering flora depend on the signals of light and darkness for reproduction. In fact, it’s one of the most important indicators they follow, regulating a great deal of their habits.

We see it all the time in nature: plants flower almost like clockwork, since they depend on it enormously to survive. Then they spread their seeds, wither, and go dormant or die.

It almost seems almost magical how they know when to flower. But the real workings behind it are quite simple: it’s science, and a science that growers can manipulate and use!


Apparently, plants that flower in fall respond to the longer daylengths of spring going summer – up until the summer solstice and fall equinox – by growing more leaves, developing larger root systems, and stockpiling energy.

After summer solstice when days shorten, fall flowering species switch gears, especially right around the equinox. Energy is used instead towards the development of flowers, fruit, and eventually, seeds in order to seal and secure their future generations.

Now, think about the possibilities if these daylight hours could be controlled!

What would happen if, even in the middle of summer, you could create post-solstice conditions – more specifically, the light conditions of autumn and winter? 

What if you could recreate blackout conditions that give your plants the 12 hours of daylight, 12 hours of darkness they need to start shifting into the flowering mode you need for a successful crop, whenever you like?

This is exactly what light deprivation greenhouses allow you to do.

Instead of waiting until autumn for the very best harvests, amazing yields can be stimulated and encouraged any time of year. Even better, the combination of blackout periods with sunlight intensity can produce larger, higher quality flowers than you ever thought possible!


When you turn to the possibilities of using science and nature in your favor with a light deprivation greenhouse, the results can be astounding.

As a highly desirable option, it provides you with several advantages: you save money while increasing your profits, as well as boosting product quality and its window of availability to your markets and customers.

The most rewarding advantage of all, however, is the peace of mind and pleasure you get with working in harmony with nature and the seasons.

Light deprivation is an all-natural, affordable, and very sustainable method that gives you amazing flower crops – and with only a gentle impact on the environment.

It can be argued, however, that it has no environmental impact at all! 

With only the use of small amounts of electricity to move blackout covers over your greenhouse at certain times of day, you skip out on more chemical methods to yield amazing product.

When using flowering science in your favor, you have happy plants and a happy environment – but best of all, you stay a happy grower.
