try this pal......Canna PK 13-14. http://www.growell.co.uk/canna-pk-13-14.html
cheaper and i known product....

earth juice bloom and meta k .

I notice that the meta k is sulphate of potash

I read somewhere (but didn't fully understand) that there are 3 different types of potash (?), is this the best kind and what is the difference?

I have also read that some of it is mined and laced with radioactive particles which can be bound to the oils in the plant as in a similar way to which has been studied in tobbacco, smoking seems carcenogenic enough to me and don't feel the need to iradiate myself in the process. This could be complete bollocks, but it is just something that I read whilst trawling a myriad of threads on god knows how many different sites

The only downside to reading so much crap is your left with more questions

I'm quite stoned, I hope this makes sense
