I have a couple of old beans I'm wanting to try and self seed ,so I've got my hands on some of the sts 2 part spray from Mr beans, had it sent elsewhere of course after hearing of the shut downs and possible data breaches by cops in recent times, anyway the stuff come with no instructions so I'm not sure if it's a 50 50 mix, how long it's good for once mixed etc so I'm hoping someone here might have some first hand knowledge and could help me out, thanks
