if you live by a petsmart (dont know if canada has those) but their topfin DHG is really good. Only problem is their stupid gel attached to it but very easy to break apart and turn into bunches.
Also when transplanting existing DHG - I still like to do the 2-3 stems (break the link of them into 2-3 per bunch*) but now they are the same family bunch. This means no competing and quicker growth. Just things I've learned along the way from trying to grow DHG haha.
*also you don't have to bunch them up, you can lay them out in a line just like runners are. DSM is probably easier to do this compared to having the aquarium filled like I've been doing.
Thanks for the compliment on the pics, just documentary photos for my reference.
