Hi Aerobuds
PH yes the range is vast and you can literally use anywhere in this range personally i have been setting at 5.8
although a lot of postings are saying lower like 5.2 witha
combination of lower nute strengths, helps the plant to sugar better.In a MJ book i read they wuz sayin as low as 4.0-as high as 9.0 befo any damage occurs
PH pens
there is a nice lill unit out that does all 3 in one
PH,salts an EC dunno the name unfortunately but its around £125
an the UV stabiliser i do not no of any uses fo it in growing
perhaps others may no.
