Nice Matt … As with your outlook our experience with levels of productivity still tip the scales in favor of the HPS lamps (DE) but find that using a room with an efficient HVAC system (in our case Stulz … Clean room qualified efficient gear) we expect our power footprint for the cultivation operation to perform in the $60 per pound cost range all in noting our latest indoor innovations are getting between 3.5 and 4 lbs per light based upon a five harvest cycle covering 20 different strains. We agree that LED’s will certainly develop over time to match the HPS performance metrics. Reply
People will be quick to accept greenhouse grown when they seeing the quality that results from doing it right. Anyone can have a basement and a light and call it an indoor grow, and we all know it takes a lot more than that. Right now, greenhouse grown can come from a few pieces of pvc and some plastic with little control or quality. That’s changing quickly. High-efficiency greenhouses produce consistent results that don’t sacrifice quality! Reply
Nice article, however what about all the power draw from AC and Dehumidifiers, etc. What if there was a machine that provides ALL of your power, without CO2 emissions or fossil fuel usage, and costs less per Kilowatt / Hour for power than grid power over the life of the machine? This Hybrid Generator will take you 100% off grid, wherever your operation is located. You-Gen Hybrid Generator is the solution in 60kwh increments. Contact me for more information.

Nice article but your LED information is not current. The story of lost yields with LED is probably related to the wattage you mentioned to replace 1000W HPS of 330W. If you use µmol/J as a measurement of efficiency you can accurately compare technologies in an accurate manner. Therefore, the most efficient LEDs will require at least 585W-660W to equal 1000W HPS on a one-for-one basis. The “black-eye” of the LED industry can be accredited to false equivalencies like this one. You will lose half your yield if you are only providing half the light. We implement LED lighting in production environments that regularly get 20-40% yield increases over HPS, triple digit percentage terpene increases and consistent cannabinoid profiles amongst both technologies.
