Biosilicon is a totally brilliant product, when used with discretion it can greatly enhance the crop, helps strengthen the plant improve terpene, aroma and resin production.
I struggled with BS, and then stopped using it. Having read carefully through this thread I now realise I made two big mistakes, which proved both disastrous and costly
Mistake A: I used way too much. For some reason I do not understand, I was using it at 5ml to the Litre! NO!!!!! I then toned it down to 2Ml or so to the Litre. Am I stupid or am I stupid? Anyhow..... that's what I did. Do NOT follow my example!
Mistake B: I used it right to the end. NO! Yes! But NO, Don't do this!
Result of Mistakes A & B: The most god-awful burn and taste imaginable. It was hard to light the spliff at all, but once lit the taste was really rather unpleasant. Not at all what one wants. Spliffs once lit were prone to go out straight away. The ash was darkest grey, almost black and very hard. It was nigh impossible at times to dislodge the ash pile from the spliff, it was so hard and brick-like. The hit was as ever, good - but oh my God, the taste was hideous and the smoking experience not nice. Not nice at all.
Conclusion: Don't follow me, Do follow oldtimer1!
Always a good idea, but especially so in this case. I intend to start using this gear properly as from now. I have a load of cuts and seedlings that are just perfect for another experiment.
Hang on, the dose ... it was ... what? Oh yeah, 10ml per Litre, that's it .... excellent!
