Colossus

Colossus – Ace Seeds

Colossus combines the extraordinary strength of Golden Tiger with the legendary Neville's NL#5 Haze, a strain that contributed significantly to the development of many classic Haze varieties in the 1980s and 1990s. This line is complemented by Double Thai (Meao/Hmong Thai x Koh Chang Thai), which gives the hybrid a particularly lemony-fresh character. Colossus has a delicious citrusy Thai aroma, rounded off with a lovely hint of sweet flowers, mango and a touch of incense, making it very refined and delicious.

This mostly Sativa is characterised by enormous vigour, strong branching and above-average yields. Experienced indoor growers can cultivate this strain well, as long as they keep a close eye on its progress. Outdoors – when planted early in the spring and with sufficient root space – very large specimens with an impressive appearance are possible. Colossus is a strain for true lovers of strong Sativas. The distinct Thai influence is very characteristic in this blend, which is perfectly reflected in the plants.
