Rainbow Glue Seeds

The three formats serve different buyer needs. Feminized seeds are the most widely available format for Rainbow Glue — stocked by Homegrown Cannabis Co, Discreet Seeds, and Just Feminized — and deliver the full 400–500g/m² indoor yield potential from the Zkittles x GG#4 genetics. Regular seeds, available only through Homegrown Cannabis Co, produce both male and female plants and are primarily purchased by breeders looking to work with this specific cross. Autoflower seeds, carried by Seed City, complete their cycle in 8–10 weeks from seed regardless of light schedule, with a slightly reduced yield ceiling compared to the feminized photoperiod version. Your choice comes down to intended use: production, breeding, or speed.

Rainbow Glue seeds are verified at 22% THC — a level that places this strain firmly in the high-potency category without crossing into the extreme range that can make a strain harder to work with. This 22% figure reflects the Gorilla Glue #4 influence in the lineage, which is well-documented for resin production and potency consistency. CBD content is insignificant, so this is a THC-forward purchase. The 22% reading is consistent across the feminized format; autoflower versions may express slightly lower peak THC due to the ruderalis genetics in the cross.

Rainbow Glue is officially rated beginner difficulty, which is notable given its 22% THC ceiling and Gorilla Glue #4 parentage — a lineage that doesn't always produce forgiving plants. The 8–9 week flowering time (or 8–10 weeks from seed for the autoflower version) is on the shorter end for an indica-dominant hybrid at this potency level, which limits the window for things to go wrong. For first-time buyers, the feminized format from Homegrown Cannabis Co or Discreet Seeds is the most straightforward entry point — you're getting verified genetics, a manageable grow profile, and seedbank support if you run into issues with germination.

Rainbow Glue seeds are currently available from five seedbanks: Homegrown Cannabis Co (feminized and regular), Discreet Seeds (feminized), Just Feminized (feminized), and Seed City (autoflower). If you want the autoflower format specifically, Seed City is your only current option. For the feminized format, comparing prices between Homegrown Cannabis Co, Discreet Seeds, and Just Feminized is worthwhile — pack sizes and per-seed pricing vary, and promotional discounts on feminized seeds rotate regularly across these platforms. All five ship internationally with varying levels of stealth packaging, so confirm delivery options for your region before ordering.
