I Just killed 2 Malawi Girls. Beautiful plants, very vigorous and easy to grow as far as feeding goes.
Now I decided to kill them because I have a back log of other plants, they weren't being done justice, and even at 14 weeks into force flowering still had 4 go 5 weeks to go.
If you want to go this route, prepare for 7 foot bushes. Honestly some of the most wild looking plants I've ever seen. Trichome development was really good but I just couldn't wait that many more weeks, plus they were root bound in the 3 gallon pots.
I wish you luc . I will definitely be revisiting the strain when I have a room and not a tent. A tent is simply unmanageable unless it's the only plant and scrog is utilized.
Eta: very stable. I didn't find a single male flower on either of the girls. I know with pure sativas intersex traits can be present.
