. A mature plant can process about 2,000 PPM of CO2 at 84 F receiving 5,000 lumens, same plant at 69 F will only be able to use half that amount. Cold water can 'hold' . A fully aerated solution at 20C/68 F is 9 - 10ppm;
i dont know if this is what you are talking about or not
record is 5in from 600w bulb(ballast set to super lumens) for 2 1/2 hours before temp hit above 83 degrees at tops(need more a/c or smaller room ...grrr)i also test light heat by holding hand palm down under bulb for a min.
with no heat stress signs i have plants tops at 8 inches away besides...
anyone else have a grow room or know someone with one that can keep their temps below 82-83 degress and a 600w bulb 7 to 8 inches away from tops?i would like to compare room size and layout

i didn't ask for help i wanted to know what people think of this plant technique.
i did get some pesticide info but that's about it.
record was 5in from 600w bulb(ballast set to super lumens) for 2 1/2 hours before temp hit above 83 degrees at tops.
doing this cause i read this ...The ideal amount is somewhere around 7000-10,000 lumens/sqft, and as long as the plants do not burn, as much light can be used as you want.
Both...
i fell understood for a change.
anyone else have a grow room that can do this? cause i spent months changing everything about my grow room to meet the temps and lumens range i wanted
this are the hps charts i been using

i changed my grow room till my tops could stay in max lumens range( 86-65,000) with grow top temps below 82-83 degrees.just had to learn bleaching from nutes problems or pH problems
iam learning and practicing plant problem diagnostics.cause unless you see the plants daily. help is people guessing from looking at pics what the problem could be.i have a ton of before and after problem pics i got from goggling. but i wanted to see the 1 or 2 days in between
someones girl is going to be upset ....lmao
i have reasons for everything i have done,its all for personal satisfaction. from the beginning i understood how people prefer to grow.i was not after a crop i wanted to built a awesome personal reference,now i have a
