I’ve read that background lighting needs to be bright enough to read a book to cause hermies, but i could be wrong. Sorry, that’s about all I know, the pros should be able to help a little more.
I was thinking about making a deflector to put out in front on the grill.
Is this in a greenhouse, or an enclosed space indoors? Either way, be careful if you put anything in front of a heater, especially one with an open flame.
I’ve never heard that, but I like the analogy. Seems like that would make sense.
May not cause a herm, but may be enough to prevent flowering if you’re not using autos. Plants “see” all spectrums of light, regardless of the bunk bro science floating around that alludes to plants not being sensitive to “green” light. A Blue flame would be just the same as a red flame.
Look into the Gas Lantern method (of preventing flowering) and evaluate for yourself if your heater is on long enough with a bright enough source of light for you to be able to see (if you can read while you’re next to the heater with no other lights on, it’s too bright).
Sorry replied to wrong topic. Well wrong reply to right topic. My theory, the only open flame around my plants is after harvest, when I’m lighting a j or bowl.
Plants are 1 month into flower. The propane heater is a ventless. Plants are progressing very well. I hope the advice you gave me yesterday about fertilizinworks out. I know the leaves that are effected won’t get better i’m just going to leave them until they get all the nutes sucked out of them and just fall off.I mixed up Jack’s last night and gave them 2 gals each pps a little over 1200 and ph 6.8 will see how that go’s.
IMO DR Bruce is the final word on all things cannabis if you ask me. He has been working on cannabis growing as a science for some time now. Good on ya @Newt for bringing him into the conversation.
I quoted him just this morning on 48-hour dark periods immediately before harvest.
Winner Winner Chicken Dinner…
If the eye is interpreting it as a light source and blue - its prolly in the 400-500nm range with some oxygen yellow flicker hitting up into the 600’s. Proximity and photo flux emission to the plant would be the Delta variable.
