My own brother uses a Vivosun, its shit compared to the Zazzy. The Zazzy is even cheaper then a Vivo. Yet all review sites rate the Vivosun #1, lol. They are PAYING review sites. VivoSun is similar to MarsHydro quality. Garbage.
I've had HydroCrunch tents, they were shit.
If you research, (theres a lot more cannabis sites then this one)......Any light during the darkness cycle can cause herming. Usually its cross contaminated pollination ( bad genetics) or breeding conditions not close to sterile. It also can be ppl stressing their plants out. Topping 4 or 5 times, excessive shock to the plant. Transplanting too often or growers that never researched to begin with, trying to grow.
Moderators don't moderate at this particular site, so instead of debates you get lower IQ individuals or white trash name calling, anybody disagreeing with their POV. It gets old.
