Adding higher wattage MH/HPS bulbs to your grow room (or increasing the number of MH/HPS units) is the most cost-effective way to increase your yields.
When you are already having trouble with heat, you shouldn’t add more lights to your setup until you get the temperature under control. By keeping temperatures relatively low during the flowering stage, you will actually increase the potency of your buds and achieve a better smell. Learn about how to lower temps with a stealthy exhaust system.
A properly calibrated exhaust system will help keep temperatures around 65-80°F (18-26°C) while buds are forming, maximizing on the final quality and potency of your buds.
Another option is to upgrade to better LEDs than the ones you have now.
If you haven’t already mastered the basics of growing and learned about free plant training methods to increase yields, you should focus on those factors first. Training your plants to grow better will give you better yields without having to upgrade your lights.
When it comes to improving your yields, the most efficient grow light is an HPS. When I say "efficient," I mean the amount of usable light produced for the amount of electricity needed. Because HPS lights are so efficient, using an HPS light during your cannabis flowering/budding phase is the fastest way to improve your yields.
How to Upgrade:
If you have less than 150W worth of grow lights in total, your grow is underpowered for cannabis growth (even for just one plant). Cannabis plants need a lot more light than many other types of plants. If you don’t have at least 150W worth of lights, it’s important you add more total grow light wattage to your grow room to make sure you’re getting the best results you can.
Using the Wrong Light Schedule
You should be careful not to leave the lights on all the time, or worse, the opposite – forget to turn them on. It might sound trivial but it’s quite easy to mess up the light schedule and even a minor change might have a negative impact the plant’s growth. Cannabis needs about 18-24 hours of light during the vegetative stage and 12 hours of light during the flowering stage.
Not Protecting and Maintaining the LED Lights
LED grow lights are your friend and an important investment, so you need to take proper care of them. They bring numerous benefits to the growing process and a little maintenance and preparation can save you a lot of trouble. It is recommended that you set up a power stabilizer and connect it to the lights in order to equalize the incoming voltage, thus protecting the chip inside the LEDs.
Using Inferior Products
Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process. If you’re using regular incandescent lights, you’re not very likely to grow strong and healthy plants. Therefore, for best results it is recommended that you use full spectrum LED grow lights. They are specifically designed for the purpose and have the feature to deliver light in the exact spectrum the plant needs.
Forgetting to Adjust the Lights
Many people forget to adjust the height of the lights as the plants grow bigger and end up with burnt leaves. Another important thing is to occasionally rotate the pots in order to prevent the plants from leaning towards the light too much.
Providing Insufficient Lighting
It is important to consider the scale of your operations. Think about how many plants you’re growing and how many LED lights you’ll need in order to illuminate them properly. You should also be aware of the luminosity of the lights you’re using. For example, a 200W LED light is said to be sufficient for a yield of about 100 grams. Make sure that you have enough lamps but still look for a good balance between providing sufficient lighting and not overdoing it.
For people who use cannabis derived products on a regular basis, it is very tempting to try growing the plant at home. The benefits are quite obvious: the cost is drastically lower and there aren’t any hassles related to the actual purchase of medical marijuana.
Many people all around the world grow cannabis at their homes, be it for recreational or medicinal purposes, and while some of them do quite well and manage to produce a good product, for others it doesn’t work so well – their plants wither quickly or produce insignificant yields.
Setting the Lamps at an Improper Distance
Overheating or insufficient lighting can result from having too many or not enough lights, but it can also result from placing the lights too close or too far from the plants. There is no universal rule for setting the distance but it’s recommended that LEDs are placed 12 to 18 inches away from the plants.
Overwatering When Switching from HIDs to LEDs
Regular HID lights produce a lot of heat and generate lots of infrared light. This dries out the plant and the soil and results in the need to water the plant more often. However, LED lights generate no infrared light and don’t emit nearly as much heat, so there is no need for abundant watering.
Here’s a Pineapple Chunk plant I’m growing under the HLG 65 (4000k version) right now. Look how big the buds are at only week 5 of flowering!
Kind LED panels have recently been becoming very popular on the cannabis growing scene and seem to be getting great results especially when it comes to yields. However, they are definitely pricey even for LEDs, so that is a big consideration!
