Do I need to include hashtags or so?
ofc hashtags do the job. just choose good ones. which are good one? that is a question!
i recommend you to add #mushroom and try #medicinal #gogreen #gardening and also #ecotrain (this one covers everything from nature, permaculture, environment, earth building, spirituality, alternative ways of living and Being and basically anything that relates to changed interactions with one another and Mother Earth. New paradigm stuff. :)
maybe entering to #AmazingNature challenge will help too? if you would want to work on making your community More Visible to the folks -- then do it.
your stuff is awesome!
