Haven't been on here in a while, but thought I'd share my experience with HSC. I don't know why there are some people trashing them on here, as I've only been super impressed by their products. Never had a herm in 25+ full term plants, and yields have always been heavy. So far I've grown:
Stoopid fruits
Bigfoot glue
Squirt
Hibiscus
Vanilla frosting
Hella jelly
My favorite smoke so far is the vanilla frosting at night and squirt in the daytime. VF produces beautiful super dense nuggs that smell like pure vanilla gas. The squirt on the other hand is an amazing throwback for me and the tangie terps are definitely prominent. Slow to veg, but finishes strong with relatively huge colas. Smells out of this world.
Stoopid fruits is fun to grow and I've seen a few phenos so far, all great. One was had a grape profile, one reminded me of g13 and had massive colas, and the third was super gassy and citrusy. Completely covered in trichomes.
Hibiscus is one I'm suprised hasn't caught on more. It outgrew everything last year and again this year. The colas were bigger than 2 liter soda bottles. Last year I just let it go in a 45 gal in the greenhouse and it grew to 12 feet. This year I put one outside in a 100 gal but only 80% full and another in a bed. Edit: i topped the hibiscus in the 100 gal 6 weeks into veg. The one in the pot grew way bigger. Super consistent stock, the geno/pheno seems to be stable with little variation. I'd describe it as berries with a hint of fuel. The plant goes purple if you let it, especially in late October with the cold nights. It's zkittlesXblueberry muffin, both of which have been major hits. This deserves the same attention I think. The smoke is really potent. I get a little too zonked so I generally stick with either something more relaxing or uplifting, but perfect for those who smoke all day/everyday.
Hella jelly was a new addition this year and I have high hopes for the final product. I grew 3- one in a 45 gallon and 2 in a bed side by side. Started all mid-late june and each one grew to about 8 feet. 3 different yet similair phenos with one having pretty different bud structure yet similair fruity nose. They were all super duper frosty and completely white with crystals. Trellising is highly recommended as the stems seem to lose some structural integrity late in flower. But I also don't cut early, and see that with a lot of strains the branches will appear to be falling over with the weight 2 weeks after they initially looked finished. These were less robust though at harvest and I could pinch the stems and they'd collapse.
