Rainbow Kush Auto
Rainbow Kush Auto โ hybrid, 22% THC on the listing, euphoric, focused, refreshing. Sent in plain packaging with NZ Post tracking and covered by our germination promise.
What the seed lot did on the bench
Every lot is checked before it goes on the shelf, and the yield figures come from New Zealand growers who sent us a harvest weight against a batch code. This lot was read on 2026-09-07, from a tray sample of 240.
Outdoor figures come from a New Zealand season, so they run below what the same cultivar reaches somewhere with a longer, drier autumn. Treat them as what this plant does here. The full report for this lot sets out the method and the terpene panel.
About Rainbow Kush Auto
Rainbow Kush is bought for what comes off it, and the sourced figures are 350-450 g/m2 under lights and 400-600 g/plant from a plant grown out. Those are ceilings, not promises โ pot volume, light intensity and how honestly you feed decide where you land inside them. Run the numbers for your own tent with the yield calculator before committing to a pack size, and put it next to the rest of the high-yield strains if weight is the whole point.
Getting the Weight Out of Rainbow Kush
What the sourced data gives for this cultivar: 350-450 g/m2 under lights, 400-600 g/plant from a plant grown outside. Reaching either is an environment problem before it is a genetics one.
Root volume sets the ceiling before a single flower forms. Under-pot a plant and no feeding schedule rescues it. Get the container right early and the plant does the rest.
Light is the second lever, and the one most growers get wrong in both directions โ too little through veg, too much in late flower where it bleaches rather than builds. Steady beats aggressive.
The third is the fortnight around the flip. Autoflowers give you no flip to manage, which is exactly why the vegetative period has to be right the first time โ there is no second chance to fix a stunted start.
Feed to the plant rather than the calendar. Our nutrient calculator gives a starting schedule; the plant will tell you where it is wrong. Worth a side-by-side comparison before you commit if weight is the deciding factor.
What Rainbow Kush Is Like
Reported effects cluster around euphoric, focused, refreshing. At 22% THC that is a meaningful figure rather than a decorative one, and the sensible approach with anything in this range is to start lower than you think and wait longer than feels necessary.
The 50/50 balance shapes where it lands: even-handed, with the dominant direction shifting by dose more than by time of day. Tolerance moves this more than any other variable, which is why two people describe the same jar differently.
Prefer something gentler? The CBD-forward strains range trades peak potency for balance.
The Terpenes
Myrcene leads, limonene sits behind it, and pinene runs underneath.
This trio is a common signature in well-regarded cultivars, which is not an accident: myrcene carries weight, limonene adds definition, pinene keeps it from being one-note. It reads clearly on a first opening rather than needing to be hunted for.
Who It Suits
Rainbow Kush is rated easy. That makes it a reasonable first grow โ it survives inconsistent watering and imprecise feeding without collapsing, which is what a first season mostly consists of. Being an autoflower removes light-cycle management entirely, which suits balcony growers and anyone wanting a fast turnaround.
Shipped nationwide in plain packaging. Every strain page carries whatever grow data we could actually source, and nothing we could not.

Where Rainbow Kush Auto Comes From
We hold no documented parentage for this cultivar, so none is shown. A blank here is an admission rather than an oversight โ we would rather leave it empty than publish a lineage we cannot stand behind.
We did not originate the cultivars in this catalogue and do not claim to have. What we do is select and stabilise the lines we sell, so that a pack grows out more uniformly than an unworked one โ which matters more in New Zealand than in most places, because an outdoor grower here is working to a frost date rather than an open-ended season. The stabilisation programme sets out how that works and what it does not cover.
Every pack is covered by our germination promise: follow the method in the germination guide and seed that fails to open is replaced free within 30 days.
