At Grow Controlled LLC, we are always looking for ways to improve and implement the best growing practices. Historically, cannabis products have grown very well in mountainous regions. With modern technology, our patent-pending GCPA grow rooms can simulate those higher altitude growing environments by simply reducing the oxygen level around the plants, letting them exhale as easily as they do in the mountains. When altering the oxygen, our in-house laboratory trials where the only variable is available oxygen (14% vs 21% O2) have proven to yeild 18-20% more flower production. We continue to push the cannabis plant into higher production by using automated control of oxygen and carbon dioxide levels. The possibilities also exist to alter light cycles, which allows for substantial energy savings, or even the ability to squeeze in an extra grow cycle every couple of years. These patent-pending pressure atmosphere concept and GC PA grow rooms enhance the production, decrease microbial activity, and offer quick payback for the extra steps needed to complete the GC PA process.
