Qui dit que le cannabis a forcément besoin de tout le spectre ?
Pour commencer, il n'utilise pas le vert ...
Bon, celà dit, ce serait quand meme un gros coup de "bol" que le canna n'utilise que le spectre des HPS



(c'est ptet a cause de l'amnesia haze mais l'histoire du "dark cat" qui absorbe la chaleur m'a fait rireLumen's are Hard to explain.
but basically lumen's is Human EYE energy.. and not directly related to plants..
the CMH puts Usable energy across the board..
i been trying to find a way to explain that in short but it gets long..
as far as heat the bulb itself gets hotter however (same temp though as standard MH bulb) but it doesn't THROW heat.. (when i play with my cmh my cat will sit 400mm from it if its HPS bulb same watt wont go near it and if i hold her 900mm from it she gets hot and wants to leave she is a dark cat so she absorbes that heat, so it shows CMH dont throw heat)
you can get your plants closer to light..
in turn Inverse square law of light plays in.. giving u more energy..
I have seen a 400 CMH 1 inch 25mm from the top of plants with no bad effects (good air cooled hood and Airflow in Grow area)
it also keeps plants shorter without loosing yeild..
its more of a see it to belive it type thing..
basicly every thing we Knew about lighting Forget it.. for CMH..
example:
i just converted a local petrol station to CMH they usto run 24 400 Watt MH lamps and now use 20 250 CMH lamps but the customers and Test data showed more Light..
for plants its not exactly same but shows kinda..
also on HPS lamps at 50% life there lumen's are less than half what they started (basically)
but the CMH holds 85% so in fact at 50% life to end of life the CMH is putting out more lumen's AND also REAL ENERGY the plant can use..
