I've grown both Ace Malawi and Panama indoors, and the Panama outdoors in Southern California many years ago. There is no difference in the high as long as you give them enough time to ripen indoors. Panama finishes sooner than the Malawi, but both take longer than most strains nowadays. I think I started harvesting my ripe Malawi buds at around 22 weeks-the buds on these landrace Sativas won't ripen all at once, or even very close to the same time, so just keep an eye on them and harvest when they are ripe. I prefer growing outdoors, but honestly, it was easier to keep them healthy indoors-4, 5, 6 months is a long time to protect your plants against weather, insect attacks, fungal infections, etc. They are monsters indoors, so maybe consider starting at 12/12 from seed. Good luck!
