A one-person team built Leafist in 2016. I'm Parker Ruhstaller and was born and raised in California.
I built Leafist after wanting to exercise my medical marijuana cardholder rights by purchasing a few clones from Harbor Side Health and CBCB (Cannabis Buyers Club Berkeley) around 2014.
My initial grow setup was absolute garbage. It consisted of various PVC pipe that I assembled in my one-bedroom Oakland apartment. But, it worked! I did, however, run into a plethora of issues including: fungus gnats, nutrient deficiencies, nutrient overload, etc. Despite all these problems, I realized that growing cannabis (or any plant, really) is not only therapeutic, but has an outcome that can be determined by how well you care for your plants -- which is challenging, but very rewarding.
While cannabis is quite literally just a "weed", I found that in order to grow decent flowers, there are all sorts of techniques to learn and didn't necessarily know of a place to get information quickly. The resources I did find, were catered less to growing and more to the consumption of cannabis.
The goal of Leafist is to be a resource, community, and marketplace for cannabis growers.
