True Wattage or Actual Watts

Posted on 14/10/2019

LED grow lights are sometimes compared by looking at what has been called, true wattage, actual watts or even draw from the wall. This post looks at what these terms are and why they are misleading when comparing LED grow lights. This post is adapted from Feed The Seeds. Understanding Watts Watts are a measure of power. Electricity can be measured with three different metrics: voltage (V), current (I), and resistance (R). Voltage measures the

Quantum Board and Chip On Board

Posted on 12/09/2019

The rapid pace with which technology moves have not left any industry untouched. The same holds true for grow lights. Grow lights have evolved from high intensity discharge (HID) to light emitting diode (LED). A number of new developments have taken place within LED grow lights over the years. Two of these developments are Quantum Boards and chip on boards (COBs). Introduction What is a Quantum Board? Horticulture Lighting Group have frequently been attributed with

Cannabis extracts in detail

Posted on 05/08/2019

Cannabis concentrates – and cannabis extracts – come in a range of product types, forms, and consistencies. The source material from which the final extract is derived as well as how the concentrate was extracted determines the purity and chemical composition. This post is a summary of part three of the four part series from Leafly. The summary of part one and two can be found here. We love using Leafly for strain related info
Cannabis concentrates, oils, and extracts offer many unique benefits that you won’t find from smoking flower. From easy, precise dosing to clean and refined flavours, concentrates focus on the ingredients in cannabis that matter most. This post is a summary of part one and two of the four part series from Leafly. We love using Leafly for strain related info and more! Definition and types of concentrates Cannabis oils, concentrates, and extracts—these all serve as

Grow light efficiency

Posted on 01/08/2019

The topic of a previous post was Photosynthetic Active Radiation (PAR) and Photosynthetic Photon Flux Density (PPFD). PAR is the band of wavelengths between 400 nm and 700 nm. PPFD is a measure of the photons hitting the plant. This post will focus on another important measure for deciding on a grow light, grow light efficiency. PPFD is a measurement of light intensity within the PAR wavelengths and is measured in µmol/m2s1. The efficiency of
