I grew 2 of the femmed versions outdoors last year - both indica type phenos - one green, one purple tinged... Very easy to grow, reasonable yield considering shit weather, but I did suffer from a little mold on the purple one. I preferred the green version smoke-wise. ( I use a vape)
As Withnail says, nice smell and nice unique taste ( I thought ) however it was quite mild stone-wise... but definitely ok as a mild daytime smoke (or night-time actually) if you have nothing else

I also took cuts off both plants and flowered indoors under hps, these also grew very well and had better yield but the high from the outdoor grown versions seemed much clearer, nicer, but still weak by comparison with other strains. So if you are looking for strong stone and/or soaring highs... look elsewhere!
I would still try other Mandala strains ( I like the look of the new ones they've got out this year ) as the price is right and their strains tend to be a bit different from most other vendors but I don't think I would grow Mandala #1 again.... that being said... I bubbled some of the buds/trim and the hashish was VERY nice...
