Switch from HPS to LED Lighting
[Case Study]

Xotics Cultivation

MegaDrive™ Lighting Technology

Based in Lompoc, California, Xotics Cultivation
got its start operating with a single level HPS grow operation

Xotics Cultivation in Lompoc, California got its start operating with a typical single level HPS grow operation. While they had seen success with this setup, they wondered whether switching their methods could produce both higher quality crops and a more energy-efficient operation overall. In 2020, they decided to modernize. This meant both moving to a two level set-up and replacing HPS lighting with LEDs.

At the time, Xotics Cultivation had been using HPS lighting for two years. A two level grow set-up could potentially increase efficiency, yield, and the overall quality of the final product. However, double-stacking HPS is impractical as it would require 20foot ceilings and intensive manual labor. Not only that, LED lights would more evenly distribute heat, which could create a better atmosphere for the plants overall. This is why the Xotics Cultivation team looked into LED lighting, specifically interested in the new MegaDrive system from California Lightworks.


Before Harvesting

One day from harvest, the changes to the plants were noticeable from observation alone. The plants appeared taller and thicker, producing more trichomes as well as frostier buds. This was an indication that LED lights were improving the quality of the yield. It also indicated there would be more pounds per square footage once the final harvest was complete.

Xotics’ move from managing a single level to a double level was a bit of a challenge, but working with LED lighting itself was easy once setup was complete. While the team had to make some tweaks to their feeding schedule to accommodate the change in growing environment, once they found their footing with this new set up, the grow cycle ran smoothly.

The Advantages of the MegaDrive™

MegaDrive can run up to 30 400watt LED fixtures from a single central power source. These fixtures come with dual spectrum control and separate channels for red and white. You can operate MegaDrive from any wireless Bluetooth device, allowing you to change light settings remotely from a smartphone or tablet.

The lack of power drops over the canopy or under the shelving made it quicker and easier for Xotics to set up the MegaDrive system. The setup also created better heat distribution. The heat of individual drivers no longer caused unwanted temperature fluctuations, keeping the temperature both stable and optimal throughout the growing process.

Setting up MegaDrive was relatively easy for Xotics, with installation only taking a couple of hours total. Once it was set up, they hoped to see both a higher energy efficiency in terms of grams per watt, as well as higher quality yields overall.

At Xotics, the team does lab tests on every strain, making it easy to measure results and track changes in yield quality in order to determine whether LED lighting is a worthwhile investment.

After Harvesting

After harvesting and processing their buds, Xotics looked at various metrics to determine whether the MegaDrive Greenhouse Lighting Technology would be a worthwhile future investment. The results were promising.

According to the lab reports, the plants grown under LED did show noticeable improvements. The terpene profile was higher in the flowers grown under LED lights. They also noticed trichome improvement and frostier buds, qualities customers often look for.

Despite not expending any extra energy, the yield increased overall under LEDs. A single row of HPS lights produced 36 pounds per row, while a double stack of LED lights produced 60 pounds per row.

This marked increase in yield means that – despite the higher upfront costs – LED lights will make more money over time. Within just a few more cycles, the investment will have already paid off due to an increase in efficiency, quality, and pounds per row.

Future Plans

Moving forward into future plans, Xotics plans to make a full transition to LED lighting as they expand their business. They are in the process of converting their outdoor space to a 30,000 square foot, 1,200 LED light building. Higher ceilings and more space will allow the plants more space to grow and thrive.
