1 Light Cannabis plants love light. When planning a garden opera- tion, be it be indoor, greenhouse, or outdoor, light is the most essential variable for success. For indoor marijuana gardening, the design of a successful lighting schematic can be a challenge for the inexperienced grower. To illustrate, different types of lighting, such as high pressure sodium (HPS), metal halide (MH), light emitting diode (LED), and fluorescents, all present unique variances in their applications. For example, an HPS light covers a different square footage of canopy and utilizes different levels of wattage than an LED light. One thing rookies need to be aware of is not positioning their chosen grow lights either too close or too far from the garden canopy. Hanging lights too close to foliage can easily burn leaves, while placing them too far from the canopy will cause plants to stretch. Overly stretched cannabis plants wreak havoc on the small confines of indoor grows. A careful study of the proper use of a chosen grow light can help alleviate most of these issues. A majority of this information is available online and on product packaging. Greenhouse and outdoor cannabis growers should always position their gardens in areas that maximize sunlight. An additional two hours of direct sunlight on a garden can have huge impacts on harvest totals. Of course, the world of legal cannabis growing is still in its infancy, and it’s important for cultivators to weigh privacy and security concerns with the utilization of available sunlight. Still, a common mistake made by novice greenhouse and outdoor growers is to hide their gardens under trees and out of the sun. While this is understandable from a security perspective, planting a garden in the shade will greatly diminish the size of a harvest. 2 Water “For novice gardeners, it is important to understand that all cannabis cultivators, no matter how advanced, are after this same goal.” 36 Maximum Yield Water presents an extremely important yet difficult-to- master variable in cannabis cultivation practices. As such, proper watering technique is probably the most problematic factor for new cannabis growers. While indoor, greenhouse, and outdoor gardens each have different environmental constraints that dictate how often cannabis plants should be watered, basic irrigation rules apply to all these cultivation practices. Novice gardeners are notorious for overwatering. While there are countless reasons as to why this happens, a primary one is simply that new growers like spending time with their plants. It is well and good to be excited about cannabis growing, but being a skilled horticulturist requires patience and attentiveness. Overwatering causes countless problems with essential plant functions, from nutrient uptake issues to root rot. Cannabis plants like their root zones to dry out between watering sessions. Of course, proper irrigation requires a careful balancing act as it is harmful to let root zones dry out to the point that the leaves of the plant wilt. To make things more complicated, shifts in weather patterns and temperature affect when one should water. It takes some practice to understand when the best time to water might be.
