Rosslyn Direct is built on one simple idea
If we treat the plant with respect, it gives us everything we need
We work with clean growers, wash in small batches, and only press solventless. No cut carts, no mystery blends, no mass-market shortcuts. Just THCa rosin and flower that feel as good as they taste
At the federal level, THCa products are legal when they are hemp-derived and stay under 0.3% Δ9 THC by dry weight
That’s exactly how we build Rosslyn Direct. Every batch starts with compliant material and is tested so you can see the numbers yourself. Always check your local laws, but we design our lineup to stay on the right side of the Farm Bill

We ship to most U.S. states that allow hemp-derived THCA. We do not ship to Arkansas, Idaho, Minnesota, or Hawaii. Orders from restricted states will be canceled and refunded.
THCA is the raw, non-psychoactive form of THC found in cannabis. When heated (like in a dab rig or vape), it converts to THC and becomes active. Our rosin is high in THCA and remains non-psychoactive until activated by heat.
We produce small-batch, solventless THCA rosin and vapes—no solvents, no shortcuts. Our products are shipped cold and always third-party tested for purity and compliance. Unlike otherbrands such as Crisp, Simply Mary, Arete, Hello Mary we only sell solventless products.
