Stop Spectrum Tuning - There is no Seasonal Spectrum
May 26 2023 – Danielle Daly
🚨 Did you know that the spectrum doesn’t change much during the seasons? Did you know green is one of the most photosynthetic active wavelengths at high light levels?
We are happy to see less marketing of Spectrum tuning with seasonal settings. But if you are sold spectrum tuning - ask for the research to support the settings and how it’s better than a nice 𝐟𝐮𝐥𝐥 𝐬𝐩𝐞𝐜𝐭𝐫𝐮𝐦 - 𝐟𝐮𝐥𝐥 𝐭𝐢𝐦𝐞?
Also come to Mammoth on what the setting should be vs their recommendations. Most “formulas” will say more red during flower. But more red reduces cannabinoid production with little effect on yields.
Don’t get us wrong - experimenting is great, we just want to lay out the research to support any settings.
Heavy light and a full spectrum will deliver the best results (highest yield and quality) 🌱. UNLESS you are attempting to shape the plant (less/more stretch - then we could make a case for tuning).
A common “formula” is to deliver more red (vs blue) during flower. Studies show additional blue in the spectrum increase cannabinoids (THC, CBD). So you need to ask the below questions:
1. By increasing the Red…..did you Reduce cannabinoids as the Research would suggest? Was that really your goal or was the “formula” wrong?
2. When you increased the red and decreased the blue…did you LOWER overall light intensity/ppfd and Yield (light intensity and yield are linear with an R2 of .8)? Did you want lower yields?
3. If your light has power adjustment to deliver the same canopy ppfd during the adjustment phase – what is the max amperage per diode? If they are running too high/hot…you are reducing the overall life of that diode! WARRANTY issues.
4. End of Day (EOD) Far Red. All that Red Light to put the plants to “sleep” faster. Zero research to support this. Dr Bugbee cannot produce any trials to support this and research on traditional LDP and SDP concludes the same. Why doesn’t that extend the flower period if it’s so plant friendly???
5. More blue can keep plants shorter and internodes tighter – so that could be a positive!!
