aye that sounds helpfull as fuck lol. truncheons cost a fortune!!
i use this
View attachment 812090 pay attention for a week and itll drop to about £35 at some point. i payed £30. this thing IS Flawless! perfect reading after 20 seconds. holds the screen once its settled so you dont have to hang your face in the buckets........ its waterproof aswell thankfully. ive tried to drown it more than once lol.
no calibration, no testing it.
it works 100% from the word go. had it nearly 4 months now and its still point perfect as far as i can tell. i know my tap water is 7.3 at 058ppm and actually while we're at it my ppm metre is fuckin amazin and it only cost a tenner. had that for 7 months or so... hang on..
View attachment 812092there we go : ) that thing is the most usefull ten quid ive ever spent. dictates my entire feeding/res change schedule for me. numbers go up you add more water. numbers go down you add more nutes.
try to keep the number steady.
cant go wrong : )
monkey see, monkey doo, monkey grow massive weed plants.
simples : )
no need for thought or complicated feeding charts, just follow the numbers...... hmm.... that would be quite a usefull thread actually if i can figure out how to write it down in a non stoned out my head way lol..... hmmm..... ..... tbc......
