What the sources agree on
Green House describes its line as vigorous, with a Christmas-tree shape and long secondary branches; High Times likewise describes vigorous branching and strong flowering stretch. Both accounts support planning for a tall, branching plant, but they are cultivation descriptions rather than universal phenotype rules.2,4
Feminized line, autoflower and high-CBD version
The Green House product page opened for this guide is its feminized Lemon Skunk × Super Silver Haze line. Weedmaps says Green House also developed an autoflowering Super Lemon Haze by hybridizing with ruderalis, plus a high-CBD version bred with a high-CBD male; those are distinct seed products with separate parentage.2,5
Seeds and the law in the US
CRS says the amended federal hemp definition uses total THC including THCA and excludes viable seeds from cannabis plants above 0.3% total THC on a dry-weight basis. Most delayed provisions take effect December 11, 2026, while the synthetic-cannabinoid exclusion begins November 12, 2026.6 This site does not sell seeds.
