My friend is pulling 1.8g/w with two plants flowering under one 640w led from these guys highpar.com.auCan you guys get 1.5g a watt?

I can keep em close enough to get light bleach ~ 25-35cm. Is that 1.8-2m total height ,meaning that including pot height and light or is it that you could have a 1.8-2m plant?Hey bully I am setting up a new room and it's limited for verticle space (1.8-2m) and I'm trying to decide whether to go high end led or MH/HPS....
With cool tubes or a ducted hood how close to the canopy can you keep your 600w HPS?
Yeah its such a subjective thing anyway i can hit 1.5gpw but i grow sativa doms that a very good yielders, theres no way to compare ourselves to each otherDoes it matter?
And its missing the important factor of time. Plus most dont actually add all the grow room Watts up and just factor in lights.Yeah its such a subjective thing anyway i can hit 1.5gpw but i grow sativa doms that a very good yielders, theres no way to compare ourselves to each other
Exactly. Its a pissing contest.And its missing the important factor of time. Plus most dont actually add all the grow room Watts up and just factor in lights.
I get why commercial growers worry about it but for the home grower its very meaningless. Quality is generally smaller yielding strains or longer flowering ones and both those ruins a Gram per watt X time.
Is this loss due to the refraction caused by the curvature in the glass of the cool tube or simple because the lights passing through glass?its about 10%
Probably all those things.Is this loss due to the refraction caused by the curvature in the glass of the cool tube or simple because the lights passing through glass?
Any opinions on cool tube vs ducted hood with flat glass surface?
end of the day time is the more important factor. The difference between a 8 week strain and a 9 week strain is an extra cycle a year.Yeah its such a subjective thing anyway i can hit 1.5gpw but i grow sativa doms that a very good yielders, theres no way to compare ourselves to each other
1.8-2m total height to ceiling (rooms on a slope) about to purchase some lights so tossing up whether go led or HP's in the past I've used HP's/MH but that was years ago and leds are undoubtedly getting alot better so it makes the decision alot harderI can keep em close enough to get light bleach ~ 25-35cm.

I cant answer that.Is this loss due to the refraction caused by the curvature in the glass of the cool tube or simple because the lights passing through glass?

LEDS are awesome.1.8-2m total height to ceiling (rooms on a slope) about to purchase some lights so tossing up whether go led or HP's in the past I've used HP's/MH but that was years ago and leds are undoubtedly getting alot better so it makes the decision alot harder
Yep which is why i shit myself when i realised my amnesia haze #2 is done in less than 8 its my fav smoke but it yielded only 1.75lbs but if it will yield me that in less than 8 weeks its a completely diff ball gameend of the day time is the more important factor. The difference between a 8 week strain and a 9 week strain is an extra cycle a year.
I know my mates struggle with that head height with hps but that is growing the tall strains i grow1.8-2m total height to ceiling (rooms on a slope) about to purchase some lights so tossing up whether go led or HP's in the past I've used HP's/MH but that was years ago and leds are undoubtedly getting alot better so it makes the decision alot harder
Makes sense you would get more light to the canopy using a ducted a hood from the reflection of the hoodI cant answer that.
I believe that duxted hoods are better than cool tubes, this could be because with a cool tube the globe is surrounded 360 degrees by glass so all the light that is emitted directly upwards into the light hood then gets reflected back through the cool tube again obviously incresing the amount of times the light passes through the glass and increasing amount of light degradation - these are just my thoughts not facts tho
If you spend the money on quality and run them correctly . Personally I think climate control is even more important with led to keep up transpiration rates without the ir boostLEDS are awesome.
Yeah but it probably doesnt make a big difference.Makes sense you would get more light to the canopy using a ducted a hood from the reflection of the hood
Any brands you would recommend I look at?LEDS are awesome.
and are cooler.Yeah but it probably doesnt make a big difference.
Cool tubes have hoods to
