im sure theres a perfect temp/humidity for each weed.....but if my cupboard is somewhere between 17-32 im not much bothered.now its about 23-30c.
when was the last time the pen was calibrated ? having had a yellow pen,id now prefare to work blind than think my ph was 8 and add ph down,only to discover pen was reading +2.my ph was 6 and ive just added ph down making it ph4,it was/would have been fine if left alone.
but we only find these things out after the event.
if plants is happy n healthy no reason to think ph is off.take any reading from pen with a pinch of salt.
bit of a silly question but...does yer kettle fur up ?
good luck n keep er lit
I calibrated it last week and it was fine, it didn't need adjusting. Fur up as in collect limescale or actual fur? lol
and seems to be keeping true.
but would mean your tap water should have more than enough cal/mag.
