Growing cannabis using Screen of Green (SCROG) is one of the most well-known cultivation methods employed by many growers, particularly those interested in maximizing their yields. As with any cultivation process, there are certain issues that can arise when using the SCROG technique. However, with the right know-how and preparation, these common issues can easily be avoided or solved.
A common issue that comes with SCROG is making sure plants have enough light exposure for both sides of their canopies. Without proper light distribution, plants won’t be able to take full advantage of the SCROG technique, as their growth will be sparse and stunted on the undersides of the screen. An equally important concern is making sure the light is bright enough as it can be difficult to achieve ideal brightness from LEDs alone. In this case, HID lights are a good option for supplementing light output.
Another common issue for SCROG growers is wind stress, especially when growing outdoors. Missing out on potential yields, especially when dealing with larger plants, can be significant due to the wind causing the limbs of plants to sway and, in some cases, snap. A good solution to this problem is the use of a reflective windscreen to direct the wind away from cannabis plants.
Under- and overwatering can also be an obstacle when growing cannabis using the SCROG technique. Plants placed in a SCROG can easily dry out in between waterings and then become over-watered once fed again. This can create an uneven growth pattern due to the high light trapped under the canopy, and can even lead to fungal issues such as root rot. To prevent this, growers should ensure they are working in a relatively dry environment and that they are monitoring their plants’ saturation daily with a soil meter and hygrometer.
Lastly, one of the biggest issues that can arise with SCROG is adding too many branches to the screen. Not only will this cause a large amount of stress to be applied to the branches, but it can also cause surrounding branches to fight each other over space and light resources. By either waiting to add certain branches until later on in the grow cycle, or by training plants to become bushier with good pruning practices, this issue can easily be avoided.
Overall, with a bit of knowledge and preparation, most of the common issues growers encounter with the SCROG technique can easily be avoided or solved. The key is to stay mindful of the needs of cannabis plants and to troubleshoot any potential problems early on in the process. By doing so, SCROG growers can maximise their yields and harvest healthy, rewardingly powerful buds.
