Harvest outdoors twice using these cannabis seeds

Have you ever harvested two successive outdoor cannabis crops in the same season before? Many autoflower growers do it routinely simply by selecting autoflower seed varieties that are particularly well suited to outdoor life. European outdoor growers as far north as England/Denmark are able to get two successive auto crops in a favourable outdoor season. Find out our expert tips as well as the best recommended cannabis seeds in order to double up your production this season.

How to achieve two cannabis grows in one outdoor season

To grow from autoflower seed to harvest typically takes around 11 weeks indoors. Outdoors, depending on your latitudes and local weather patterns, you can add an extra 2-4 weeks to that. The fast grow cycle means that many growers can get 2 successive outdoor autoflower crops in a single season. And many outdoor/guerrilla growers do exactly that every year. Those in Mediterranean climates may even be able to manage 3 successive outdoor autoflower harvests.

There are several keys to success:

•    Many experienced outdoor growers germinate their autoflower seeds indoors and grow them under LED lights for 2-3 weeks. This gives them the best possible start, allowing the seedlings to avoid unexpectedly bad weather & pests while they are at their most vulnerable.

•    Choose autoflower seed varieties with proven outdoor durability and toughness. All auto strains offer speed and convenience to the outdoor grower. But some offer particular resilience across a broad range of grow conditions making them obvious recommendations.

•    Prepare and maintain your outdoor grow location as well as you can. Our guide to growing autoflower seeds outdoors is full of useful tips and expert advice.

Why autoflower cannabis seeds are your best option

Autoflower seeds may not have the same outrageous yield potential as the heaviest yielding outdoor photoperiod feminised seed varieties (e.g. Frisian Dew, Passion #1 etc).

But with an autoflower seed-to-harvest grow cycle of around 3-4 months, autos can grow rapidly and repeatedly if the grow season is long enough. If not, you can consider a greenhouse/polytunnel which mitigates the effects of poor early/late season weather.

And/or you can germinate your second set of autoflower seedlings indoors before the first outdoor crop is harvested. Some outdoor growers use glass cold frames (small glass-box structures) to keep their seedlings warm and safe from birds/slugs/snails.

As well as their great speed, outdoor growers love autoflower seeds for their lower heights compared to photoperiod feminised outdoor seed varieties. Autoflowers typically reach maximum heights of around 1m. Autos are short & bushy enough to hide behind brambles/undergrowth making them an ideal option for guerrilla growers or those looking to grow a discreet plant or two in their garden/terrace.

Can you still grow twice outdoors with photoperiod seeds?

Not unless you live in a warm equatorial region, where each day receives roughly 12 hours of sun throughout the year. This light cycle can cause photoperiod feminised strains to bloom early with little/no veg period. The two most common ways to overcome this are:

•    For growers to cultivate their plants in the vegetative growth phase indoors under artificial lights. When placed outdoors they will usually bloom immediately.

•    Growers can use an artificial light after sunset to prevent the plants starting the cannabis bloom phase until they have reached a sufficiently large size.

Best cannabis seeds for multiple harvests in 2024

These autoflower seeds are the top-5 most popular repeat buys with outdoor growers. This includes guerrilla growers cultivating in local hills, riverbanks and waste land. It also includes those sneaking an autoflower or two into a sunny corner of their garden, terrace, back-yard or greenhouse. The low height of autoflowers, especially shorter indica-leaning varieties, makes them popular with those lucky enough to have an outdoor poly tunnel.

Auto Duck, the original & best stealth autoflower strain with a naturally camouflaged webbed-leaf shape

Auto Duck is the original stealth autoflower seed variety, using a stabilised natural leaf deformity to give camouflage like you have never seen before!

You can walk straight past an Auto Duck, especially before heavy bloom has set-in, and not even realise it’s cannabis thanks to the unique leaf shape. Instead of the iconic cannabis leaf structure, Auto Duck produces a leaf-shape that looks more like a duck’s footprint.

The individual leaf fingers fuse together creating an out-of-this-world appearance that no-one would recognise. This feature is used to great advantage by guerrilla growers and those growing a sneaky plant in their back (or even front) garden or greenhouse. Fans of this unique outdoor stealth genre may be interested to know that a photoperiod feminised seed version, Frisian Duck, is also available.

Auto Mazar: a classic indoor strain 

Auto Mazar is a classic indoor strain noted for her brain-numbing THC levels and heavy yields of sticky original Kush buds. Outdoor growers will be pleased to know that her hardy Afghani-Kush heritage gives her excellent weather resistance even for growers in borderline climates.

Auto Mazar seeds are always popular with outdoor (and greenhouse/polytunnel) growers of all types. Auto Mazar’s photoperiod feminised seed version - the legendary original Mazar, is a 1990’s cannabis cup winning original that is still hard to beat.

The resin & terpene-rich pungent buds have a rich deep-hash dankness that old-school growers in particular will adore.

Useful tips and recommendations for 2024

Choose the sunniest, warmest 6 months of the year for your double autoflower harvest project. If your climate isn’t quite long enough, then you can cheat simply by germinating your first set of autoflower seed indoors and growing them under artificial lights until the last frost has gone & the days are warm enough. You can also start your second crop of seedlings indoors under artificial light before planting them outdoors if it helps your schedule.

All the autoflower seeds in the Dutch Passion collection will perform well outdoors, but the varieties listed above are especially popular repeat buys with outdoor growers for all the right reasons. If you’re looking for bargain priced cannabis seeds then check out the ongoing Dutch Passion cannabis seed sale. Many top-performing autoflower strains are on offer at their lowest prices of the year.
The Dutch outdoor cannabis seed selection will also be of interest to outdoor growers, gathering the best dozen outdoor feminised and autoflower seed varieties into one convenient collection.

Good luck with your outdoor double-harvest autoflower project!
