Mango Cherry Runtz Auto

Mango Cherry Runtz Auto is built around a very current autoflower pairing: Mango Runtz F5 Auto x Lemon Cherry Cookies Auto. FastBuds offers it as feminised autoflowering seeds, with an F1 hybrid background that mixes compact structure, colour, dessert terps and a quick finish.

The parentage is a big part of the appeal here. Mango Runtz F5 Auto from Mephisto Genetics won Best New Autoflower 2025 at the Autoflower World Cup, and is noted for compact size, fast flowering and dense, terpene-loaded buds. FastBuds’ own Lemon Cherry Cookies Auto won Best Auto Hybrid 2025 at the American Autoflower Cup and Strain Of The Year 2025 at The Grow Awards, bringing strong colour, potency and a rich dessert-style flavour profile into the cross.

FastBuds lists Mango Cherry Runtz Auto at up to 28.5% THC with CBD below 1%. The genetic balance is 35% sativa and 65% indica, so it sits on the indica side while still keeping some sativa influence in the mix.

In the grow room it is described as a sturdy, bushy plant with tight internodal spacing. The aim of the cross is to keep the compact, efficient build and rapid finishing time of Mango Runtz while adding the visual pull and more complex flavour of Lemon Cherry Cookies. Under the right conditions, the dense resin-rich flowers can develop deep purple hues.

Flowering is listed at 8 weeks, with plants reaching around 70–110 cm. That makes it a useful option where height needs to stay manageable, without giving up on production. Indoor harvests are given as 450–550 g/m², while outdoor plants are listed at 60–180 g per plant. It is suitable for indoor, outdoor, greenhouse and mixed-light setups, and the climate guidance covers very hot, hot, moderate, cold and very cold conditions.

The aroma and flavour are more layered than a simple fruit profile. Expect tropical mango sweetness, cherry candy, sour citrus and a creamy cookie finish, with the same bold character carrying from aroma into the smoke. FastBuds also lists cherry, fruits, mango and spicy notes, so there’s a sweet dessert base with a sharper edge rather than a flat sugary taste.

Mango Cherry Runtz Auto suits growers who want a modern, colourful autoflower with named award-winning parents, strong THC potential and a terp profile that mixes tropical fruit with cookie richness. It is especially easy to understand on paper: compact, quick, resinous and built around two well-regarded recent autos.
