Rainbow Breath Auto

Five hundred grams per square metre is a photoperiod figure. This is an auto, and it delivers them.

Peanut butter and toffee

The creamy side comes from Peanut Butter Breath, which in turn descends from the Mendo Breath from Mendocino County. It's a dense kush, the kind that sticks to your palate, with no fruit at all.

The fruit comes from the other half. Zkittlez has been the reference for chewy toffee sweetness for a decade, and here it comes in automatic form. The breeder's declared result: creamy kush with fruity sweets on top.

Holds its own weight

It starts with vigour and quickly forms a small, branched spruce, with main branches shooting out strongly and secondary branches multiplying below. That architecture spreads the flower throughout the plant rather than concentrating it at the top, and lets air circulate between buds, which in an indoor indica is worth as much as yield.

Silent Seeds also credits it with natural resistance to the weight of its own flowers. In an auto, where there's no room to redo staking halfway through the cycle, that detail saves more than one headache. It stays at 1.2–1.6 m.

Two ranges you need to read carefully

THC ranges from 17 to 23%. It's not a marketing bracket: in autos the percentage depends heavily on accumulated light and phenotype, and the breeder prefers to give the real floor rather than publish only the ceiling.

The outdoor one is even wider: 100 to 400 grams per plant. Those 100 are an auto planted late, in a small pot; the 400, one planted early in the season, in soil and with sun all day. The same seed pack gives both depending on when and where you put it.

That's the beauty of its harvest window, which runs from late June to late October: it allows you to chain two or three cycles in the same season, which is why many people work with autoflowering seeds instead of betting everything on one October harvest.
