hi my lights on temps are constantly at around 70f -71f ,humidity around 45% to 49% ,
is this ok ,I have 4 blue cheese ,which I cloned .in 11ltr pots coco soil .no perlite .

I can show some pics if anyone wants to see ,they just about a week to go I say ?

I haven't PH these plants or EC at all ,just some slight topping in veg ,trimming underneath .


no osculating fans .just incoming air ,and extractor fan -carbon filter .no dehumidifier ,iv only just started using the carbon filter a few weeks back as smell .

I switch air off at night ,lights out ,extractor fan off night ,just small portable heater keep temps ok at night .

If you run your Dehimidifier it will help to increase temps.

75F or 24C is ideal flowering temps.

70F is a tad low but not detrimental.

You should get some tight buds with 70F though but weight might not be great!

I had the same question a while back as my night temps ranged 63 to around 68. I was told that was actually perfect. Day was between 70 to 75. I had my best grow.

my room
6 X 4 room .4 plants 11ltr pots in coco ,on a 600w light

ho. forget to mention its in a shed outside .so fookin freezing in uk rrrrrr
no dehumidifier
no osculating fans in room
one 4 "incoming air duct ,drawing air in (cold air all day 12 hrs a day) then off at night .carbon filter /extractor on thro day 6 am -to 9 pm
all power off at (night /lights out ) ,I have always done this .except one small heat fan on at night keep things warm .

no PH testing
no EC testing /run off
I have the gear for testing .

70 is fine. would recommend putting a fan in there to blow the plants around for many other reasons though. good luck!

I remember its in a shed Jay.

The only thing I test really is EC unless I've added something like silica or PK1314 as this increases pH.

But I write notes on my wall about mls used to achieve certain EC's etc.

I too would highly recommend an oscillating fan for circulation.

Would DEFINATELY be worth measuring your RH amongst the plants.

Those plants are beautiful. Just keep doing what your doing, if you can get those temps up a few degrees great. If not don't worry about it. Cooler temps have their advantages and disadvantages as do warmer temps.
