Though cannabis is a hardy plant that can grow almost anywhere, the vast majority of marijuana grown in the United States is raised inside the shelter of greenhouses. Greenhouses give cannabis growers much more control over the nutrients their crops receive — the relative humidity, the light, the water, the soil pH and more. Plus, greenhouses provide security and privacy that many states require of marijuana grow operations.
What’s more, the technology of greenhouses is improving every year. By taking advantage of advanced tech, greenhouse weed growers can dramatically increase their yield and raise their profits, benefiting everyone in the cannabis industry.
Historically, cannabis growers strive for a Daily Light Integral (DLI) around 20, but new findings indicate that cannabis benefits from a much higher DLI. This is a result of cannabis growth cycles; the plant will continue to produce vegetation when subjected to light, and greater vegetation will ultimately produce more buds for harvest. This is particularly important when trying to promote THC vs. CBD.
In most North American regions, the sun cannot provide even a fraction of the DLI necessary for high-yield cultivation, so growers are faced with a choice: limit their yields and suffer lower profits or install more expensive lighting solutions.
