So from your latest posts it seems that your improved situation might not have anything to do with glass. More that you just had a crap setup with poor light coverage.
Nope.. my setup has been pretty good for a long time actually.. I used to share it on here a lot, but, I don't do that anymore. nothing changed except that I took out the glass and raised the lights up a bit.
Non MJ Botany is my day job .. mj plants in my care don't get much attention.. they don't need it.. they grow themselves with very little care on a small scale.
3600 watts flowering gets 2 visits a wk.. maybe 30 mins each. Doesn't take much.
Don't you just find it a bit odd that we have known about this for so many may years, yet for some reason we continue to do things counter to your ideas, and that people continue to get better yields using methods contrary to your opinion?
Ha! No.. I am not surprised actually.
You can improve your yields with many poor pieces in place.. you just won't get further than your weakest link... air, water, nutrients, light... cut one out.. they all are unable to contribute to growth..
People think more along the lines of "more light is better".. When actually, there is a much more complex relationship between your plants and light than "more is better"..
So, no.. I don't find it odd anymore.. It's the norm on mj forums, grow dvds/mags, etc..
Misconceptions, misunderstanding relationships.. I've come to expect it.. not find it odd..
Seems daft to make the statements you arte making when ignoring such important variables.
Yeah, daft.. You haven't changed one bit, have you?
It would seem VERY odd that despite knwoing of this possbile issue for so long, noone else would have attempted what you state, noticed the difference, and then "published" the results in a scientific manner.
The fact that it is not "old news" says nothing.. This hobby has more confused ass backwards traditions than any other. Truly.
Even if it WAS published in a scientific manner, Forum growers (98%) wouldn't be reading it anyway.. they don't read that stuff.. they read threads..
One thing you can NEVER argue is that people on mj forums would have figured it out by now if it worked better. OR, that people on mj forums wouldn't do something because it doesn't really work.. That's not how it goes down on MJ growing forums.
Losing some light to absorption is such a small piece of the puzzle. I don't think that the loss to the glass has nearly as much to do with what actually happens when you take the glass off and raise lights.. You have an entirely different situation.. with different light intensities, different spread.
Different temps, light levels, spread of light.. it all changes what the plant experiences.. how happy the plant is..
That is what is more important than having a TON of light.. is the plant happy?
From what I am seeing.. The plant is happier with the bulb up higher. I think it is happier with the spread and light intensity that you get going bare bulb and up higher. Higher than you see in almost all closet growers grows..
Checkout a non mj growing operation with artificial lighting.. No one is hovering lights a foot over the plant.. because there is not a culture of misunderstanding in that world like there is in the mj growing world.
You have people who aren't REALLY that into botany suddenly playing pro botanist.. this breeds all sorts of nonsense..
Also.. the plant grows so easy and it is such profitable and appreciated plant that you get people who in their local market become MJ heroes!.. You grow some bud that hasn't been tumbled, shaved and shipped and people say "You grow the BEST weed"...
and an inflated ego is born..
That's my theory, anyway..
