Hey there guys, Thought I'd drop this here so long... Please let met know what you guys think: This forms part of the main Dutch Passion Auto Daiquiri Lime Grow Series (Forum Grow Report and YouTube Grow Series). I will be building this forum topic as I get time, so just sharing the video for now as I'm quite busy with my full time job, etc. I'll post some finer details if anyone is interested and can post some decent quality copies of the photos in the video for those interested in this sort of thing (DIY light building/tinkering with electronics). Hope you guys have a great weekend! Peace.

I decided to check my knowledge on the efficiency of grow lights. From https://aeradix.co.za/grow-light-efficiency/: PPFD is a measurement of light intensity within the PAR wavelengths and is measured in µmol/m2s1. The efficiency of a grow light on the other hand is measured in µmol/J. Sometimes written as umol/j, μmol/j, umolj-1 or PPF/W. Grow light efficiency is also referred to as photosynthetic photon efficiency/efficacy (PPE). Thus, µmol/J is the amount of micromoles of photons produced per joule of energy used. The power draw of a light is measured in watts and watts is the joules consumed per second (J/s). Therefore, if you know the wattage of a single light source and the Photosynthetic Photon Flux (PPF) value, then the efficiency of the light can be calculated. For example: 1 100 µmol/s and 500 W is (1 100 µmol/s) / (500 J/s) = 2.2 µmol/J. A PPE of 1.5 umol/J is considered efficient. Anything above 2.0 umol/J is considered very efficient. For comparison, many (high pressure sodium) HPS fixtures on the market have an efficiency of 1.3 umol/J or less, with some of the best HPS grow lights approaching 1.7 umol/J. The best ceramic metal halide (CMH) grow lights have an efficiency of just under 2.0 umol/J. HPS and CMH efficiencies will increase in the near future, but LED efficiencies will increase at a more rapid rate.

Hey guys, I found a really good valued COB LED oversees but there is one thing 'pulling me back, me back' from looking at buying it... It has one main switch which turns the entire thing on instead of 2 separate veg & bloom switches. Is this a problem? LED spec: Full spectrum - 56pcs Double Chips 10watt Bridgelux/Epileds LED Chips + 2pcs x20w CREE COB Kind Regards KN
