I've grown out 2 different phenos of Belladonna on my last 2 grows.
I'd say it's a nice steady "up" high that makes a nice daytime/social smoke, I can still function while being stoned on it, quite light on flavour and smell but makes lovely, tangy bubblehash.
About the claims of it being "trippy"; well that's subjective but I didn't find it any more trippy than other sat. dom. strains tbh. It can certainly drag you off on one and lose you in your own thoughts but that's the extent of it for me. I find it to be a good smoke for playing games or watching films to because it really imerses me in whatever I happen to be doing at the time.
She's a decent smoke but nowt special and not a keeper (for me anyway). Horses for courses though innit.
Hope you enjoy it.
