i really like short riders they are a fun strain. Attitude is a seed seller so they have more selection, a nirvana is a seed producer. Nirvana is out of stock for testing because they had some trouble with a few auto strains. So really they only sell short riders as female autos.
the attitude sells lowrider seeds which are nice compact plants.
nolowryders aren't great for clones due to their tinier lower branches that would be the clones. i grow in soil but use my AG for clones and it works great. haven't used it for seeds (always gone the paper towel route) but i don't see why it wouldn't work.
If its an autoflower it would be a waste of time, stress, and everything since they will flower on their own anyways, don stresss an autoflowerer if not neeeded
