There are already private projects invested in researching the most affordable methods of growing and distributing recreational cannabis in the U.S. An effort to evaluate the cannabis industry’s LED lighting requirements and help improve efficiency estimates the best and most valuable techniques for optimization are not yet public – thanks largely to the “behind closed doors” nature of the industry from a historical perspective. But early reports from first-generation growers in Colorado and Washington suggest that those invested in sustainable energy solutions benefited most from sales in the first fiscal year of legalization, whereas those growing in indoor warehouses made up about one-third of the industry’s first year of legal energy consumption.

The first rule of choosing a cannabis clone for the basis of your grow operation is to ensure the plant intended for cloning was taken from a female plant. Clone dispensaries and resources often sell individual clone plants from $10-15 each that have already been cut, cured, and allowed to root. This can be advantageous to a quick and rapid growth cycle, cutting 2-3 weeks off your initial production time. However, clones are susceptible to mold and pests, so be sure to check the root system of the clone before your make a purchase to look for signs of infestation.

There are plenty of ways to legally acquire high quality cannabis seeds, you’ll want to carefully consider what strains to select and how your products will match up with what’s already available on the market.

Space, Basic Infrastructure, and Soil for Cannabis Production

Already considered a success in achieving water-saving status in the UK brewing industry, some cannabis producers are investing in closed-circuit desalination (CCD), reverse osmosis water systems. At the same time as purifying incoming municipal water sources, these CCD systems can recover as much as 97% of wastewater, therefore reducing water demand and saving in disposal fees.

The cannabis industry is changing fast, meaning information relevant to today’s sales data, legal restrictions, and best practices may become quickly irrelevant tomorrow. Full-time research and development efforts are important to any industry, but the extent to which changes in the cannabis world are occurring requires a closer eye to current news and industry reports.

Choosing and Promoting Cannabis Products

Auto-flowering seeds begin to flower on their own – no adjustments to light cycles necessary. These plants tend to be smaller as a result, but yields are comparable to those of regular and feminized seeds.

As with any new venture, getting started in the cannabis industry requires one thing among all other aspects: ambition. If you’re prepared to commit the majority of your time to the cannabis industry, you’ll need to be well-versed in its history as well as current events, data, and the ever-changing political climate in order to be successful.

It is absolutely imperative to closely monitor humidity and temperature when growing cannabis. Particularly if you are growing in a greenhouse, you need to ensure proper ventilation so that the air does not become too moist or warm. On the flip side, air that is too cold can be just as dangerous. Failing to maintain your growing environment can lead to hermaphroditism. While it’s possible for this undesirable development to occur genetically, hermaphroditism more often results from environmental stresses like heat and/or humidity.

Knowing when to start the vegetative stage and the subsequent flowering stage requires researching your strain of cannabis. The plants need to complete their growing cycle without interruption, during which darkness is extremely important. If you are a true beginner, be sure to start with a small crop of just a few plants. By doing so, you lower the stakes and give yourself the time and opportunity to learn the process of cannabis cultivation.

6. Poorly-Timed Light

You can’t cultivate beautiful cannabis from bad seeds. In cannabis farming, bad seeds are usually damaged or aged past their prime. Even if you follow all the cannabis growing tips out there, you still need to start with a quality seed. In most cases, that means cloning or buying from a seed bank rather than seeking seeds on the cheap from friends or unreliable sources.

A greenhouse can be a perfect place to start seedlings or raise your budding cannabis plants to maturity. Greenhouses offer a combination of protection and controlled sunlight, doing much of the hard work for you. However, there are several cannabis-growing mistakes that beginners and small-scale growers often make. Here are eight you’ll want to avoid.

8. Inferior Materials

It may be tempting to harvest as soon as you see the first opportunity. After all, you’re probably anxious for the cannabis to bear the fruit of your labor. Yet doing so is counterproductive and will lower your yield and the crop’s potency. There is no definitive or universal answer to the question, “When should I harvest?” It all depends on how potent you want your cannabis to be and the conditions in which it was grown. Generally, you want to see at least 50 percent curled or darkened pistils before harvesting – but again, this is far from a surefire guideline.

Like with most other plants, there is a fine line between watering and overwatering cannabis. The latter can cause root rot, which is usually a death sentence for the plant, as drowned roots are nearly impossible to revive. You can tell whether your cannabis is adequately watered by feeling the topsoil with your finger. If it is moist to the touch, it’s not time to water yet. Wait until that top layer is bone dry. If you are unsure, it is better to wait until you see the early signs of under-watering – such as slight discoloration or wilting – than to continually waterlog the cannabis. As you start to get your growing down to a science, you can use measurements and a set schedule based on your observations.
