You can dial the temp in to whatever suits you, who says it has to be higher?
Seems like everybody says high seventies and into the eighties when using co2. I'm used to low seventies in my fresh air room . Don't know if co2 will be affective at those temps. Gonna try a run in low seventies and then high seventies while keeping humidity ideal for those temps in order to keep vpd good. Does anyone run low seventies in sealed co2 room with increased yields?
My first co2 test was pretty cold ,i was allready running 9 kw in 3 rooms.
I decided to build a cab to test ebb/flow and co2 only free space was on the upstairs landing.
I was not able to heat it ,the ebb/flow res temp was 68 c
Id say the 3 ft x 4ft x 6ft high cab ran about 72 lights on 68 lights off
I was slightly ventilated small scroll fan high up in corner sucking via 4" duct from ceramic lamp holder 400 w osram hps 100w sylvania 7.500 k MH .
inlet was holes in floor of cab.
i was supprised at Co2 effect even vented and low temps very dark green super short internodes ,yeild 530 g cuttings vegged 2 weeks 63 day flower,i know i went through brewers tanks every 7 days but it was worth it .A
It becomes the next limiting factor in photosynthesis as I recall. spurr has a huge CO2 ppm/temperature thread around here somewhere.
Bacon.
Yes that is nice sounds like you are looking at a good one. I have a Mitsubishi mr. Slim 18000 btu. It acts the same way. The compressor has inverter technology and fan has ambient speed control. Very quite. It only runs as hard as it needs too. Mitsubishi is the best you can buy.
Running ebb/flow prior to C02 supplementation i allways had ph climb in hydroton. rez raw water was 0.0 ppm .No rise in rez ph noticed using Co2,in fact it dropped slightly once on flower cycle and using bloom nutes ,6.2 to 5.8 over 4 days
This was definatley Co2 acidifying effect.
Ive noticed this often since,A
It seemed to me looking at roots that c02 supplemented plants evolved more oxygen in lights on period.A
