Arjan's Ultra Haze #1 — Green House Seeds

Seb's take

Seb Silverback

Neville's Haze crossed with Cambodian and Laotian lines, soft and woody on the nose with a cooling menthol note and earthy undertones. The high is genuinely psychedelic — the sort that tips into philosophising and self-contemplation rather than idle chatter.

Growing Arjan's Ultra Haze #1: what to expect

Feminized photoperiod seed: every plant a female, and flowering starts when you change the lights — which puts the calendar in your hands. The photoperiod lesson covers using that control well.

Flowering takes 14 weeks — she is not to be hurried. Patience is the price of entry; the flowering guide will help you pay it gracefully.

A middling 150 cm or so at maturity — tall enough to yield, short enough to manage. Standard tent territory; the light planner sorts the hanging height.

The yield is, in plain terms, heavy — 700 g/m² when she's looked after. Branches will need support before they need sympathy; see supporting heavy colas.

THC tests under 18% by the breeder's numbers — measured rather than fierce. Some growers are after exactly that; the rest may keep scrolling with our blessing.

She smells of earth and heritage; nothing invented, nothing added.

Grower reports give her a relaxed lean: unhurried company for an unhurried evening.
