Bat Guano was always the ‘fertilizer of choice’ when the stoners would shop at my Garden Center for supplies. ;)
We had a grow light rack that had four adjustable shelves and could fit into a closet. We called it, ‘The PotMaster 5000.’
So, Bat Guano and lots and lots of SUNSHINE and you should be OK. They’re not too particular on water, but do prefer some humidity. (Mist them, if it’s not humid where you live.)
Not that I know anything about that. I mean, it’s just a plant with basic needs, Right, Officer? ;)
We’ve got a lot of the old school hemp still growing wild on our farm. Even the Mule won’t eat it, LOL!
There is dew on them every morning. The best nitrogen I can get is Blood Meal. It should also keep the deer away.
