1450 ppm co2 with 89 degrees temp

[Tamorin]

Anyone personally hit these temps ? If so any issues to note?

yup keep lights high and wait for heat wave to recide or take a light out cuz its too hot stoma damage is imminent un less your in a greenhouse mine is set at that cuz any lower and the swamp cooler will make it too humid good luck

89 is a little high. But it really depends on the strain. Some will take it no prob. The stuff I am running will start to show signs of heat stress once I start getting above 87 degrees even w/ the c02.

89 is pretty hot. and would cause heat stress most likely

co2 injected plants can handle higher temps than reg plants

isn't it that co2 plants can process more co2 at higher temps like 80 degrees, not that they can "handle" higher heat.

my source is from gardening indoors with Co2 from van patten he said that a co2 injected plant can handle up to 95 degree's but grow best around 85

i will review my books and see if i can find where i learned that but it has been explained to me how i said by numerous growers much older and wiser than i lol. too stoned to look now, but u could totally be right

every page from every book/ forum/ website puts the limit at 85 degrees with a sealed room and perfect co2

Cool thanks for info the room hits 85-88 degrees towards early morning . So I only get a few hours, but heat stress or not I'm at day 57 and they look amazing.
