Good temp?

Right now my temp gets no higher then 77 anf humidty is at 48 is that ok or does the humidty neeed to come up

it depends on what stage you are in,,,ideally you should be at 75 F and roughly 50%RH in veg and then drop it to around 30%rh in flower,

I actually run at about 80F with no ill effects,,I do make co2( by fermenting yeast) but you could run the temp up that high without CO2 but you just need to make sure they have/get enough water.

If you take the humidty to high then the stomta of the leaves wont be able to pass water out them,,so the plants metabolism slows down, maybe even stops,and if its too dry (RH OF 10% FOR EXAMPLE) then the stomta will close to presevre water.

I think your temps and rh are okay,,do you have an idea of night temp or NIGHT RH? a drop of ten-15 degrees is okay at night,,infact my temp drops from 80 to about 30ish at night an I havnt seen any problems,,I havnt measured the rh at night but I know its nice and dry so no problem. Just remember that water hold more oxygen the cooler it is,so the cooler the water the oxgen it take to the roots,,but if its too cold it will shock the plant,,so if you can tepid water..wait Im starting to rant abity,.,,yeah your temps are okay,,what about the night temps???

take it easy and happy growing.

sounds perfect!

Thanks my night temp is 68

Your all good then with them temps,, a night RH%? just make sure thats not more than 60% other wise you risk mouldy buds(only when your in flower).....

Tak it easy

my temps run 72-89 once i am in full veg then flower, my hum runs around 55 throughout. I think 78 r ideal temps & where u r at right now is perfect!

Thanks right now im in veg stage

Keep it under 84 and 60% RH, i like (personally) 75 and 25% RH, i just have to water more

I like 75* F - and 50% humidity - over 80*F and the plant shuts down - over 55% humidity and other problems can occur

not true,,can go alot higher,,you can run in the 90's (no higher than 95 cause at that tempo cholorphly,,sorry for spelling,,, breaks down)WITH co2.

Thanks guys

me think we agree to disagree

i personally wouldnt run my plants in the 90s. i know it can be done and some ppl swear by it, but personally i know i wouldnt want to be standing around in that heat for so long,so i dont pull that with my plants. i like to keep mine in the mid to high 70s and i top out temperature at 82.

Hell Im not saying it SHOULD be done,,just that it can,,and if you do run at a higher temp and balance that out with extra water,co2 etc. some times you can't keep up with the garden as it metabolises and grows faster than you could belive....

Plants do not shutdown at 80 degrees, I run mine at 82.

does it look like it's shutting down?
