Fast Growing Weed Seeds: Who Are They For?

Actually, when it comes to the fastest marijuana strains, their practical application is much wider than the simple goal of getting to smoke the product as soon as possible. The strains we’re about to present have gained recognition because they save growers in plenty of situations.

High THC Strains

First of all, if you live in a colder region with a short summer but still want to benefit from the perks of outdoor growing, fast-growing weed seeds that achieve maturity in 2 months or even less might be your only option to do so. Then, there are stealthy growers who understand that every extra day of having marijuana plants out is another chance of getting caught, so they value the rapid lifecycle. Moreover, the fastest growing weed usually also stays the most compact, which is another pro for a stealthy grower. Finally, these strains allow for not just one but two outdoor harvests in a single season! So, sometimes, it’s not only about the speed but also the productivity of your crop.

Introducing Our Fastest Flowering Strains

Now that you know how you can benefit from having fast flowering cannabis strains in your garden, let’s get down to business. In the list below, you can find our picks for the speediest marijuana plants that can be planted even late in the season and still be successfully harvested.

Top Fastest Growing Cannabis Seeds By Categories (2020 Update)

Choosing the right seeds is the first most important part of a successful grow. These selections from Autoflowering, Feminized and CBD plants are our most popular fast growing strains. They are easy to grow, produce good yields and deliver the goods all the way.

Cannabis cultivators look for specific traits when selecting a strain. Some search for flavour and potency above all else, whereas others are more concerned with speed. Luckily for both the former and latter camps, the breeders at Royal Queen Seeds have dedicated a lot of time to developing top-quality strains that are quick off the mark and rapid to deliver their goods.

Our team has created both fast-flowering feminized genetics and autoflowering genetics to satisfy all types of growers. The former offers all the benefits of photoperiod strains, but with a reduced flowering time.

Our autoflowering varieties, on the other hand, are the fastest in our archive. Infused with Cannabis ruderalis genetics, these cultivars don’t require external cues to flower. Instead, they surge from seed to harvest in a matter of weeks, making them perfect for stealthy home growers.

Let’s explore the fastest RQS cannabis seeds by category. Though the following timeframes are approximations, they are accurate.

AUTOFLOWERING

Autoflowering seeds can be both sativa and indica. However, they have been crossed with a type of cannabis called ruderalis. This enables them to flower on their own in as little as 2-4 weeks without exposing them to strict 12 hour light regimes.

Some of our most popular strains in this category include:

QUICK ONE

Quick One is one of the fastest auto-growing strains on the planet. The plant is based on the original auto flowering strain – Lowryder. This strain was created from a cross between William’s Wonder x Northern Lights x Ruderalis. These plants are usually ready for harvest in 8 weeks from germination. The plants also reach between 50 and 60 cm and can yield up to 150g per plant.

Sativa 10% Indica 60% Ruderalis 30%
100 – 150 gr/plant
60 – 100 cm

EASY BUD

Easy Bud received her name for good reason. As well as being one of the easiest cannabis strains to grow, she also boasts one of the fastest growing cycles. Her speedy and robust nature makes her ideal for those seeking a fast turnover, and those ready to take their first step into the world of growing weed.

As the progeny of White Indica and ruderalis, Easy Bud produces frosty flowers featuring a THC content of 12% alongside citrusy and earthy terpenes. These buds won’t blast you to the moon, but they will offer a soothing and subtle effect perfect for any time of day.

After germinating these seeds, Easy Bud will explode into a mature plant in as little as eight weeks. Prepare to harvest up to 325g/m² from indoor plants, and between 30–80g/plant from outdoor specimens.

ROYAL BLUEMATIC

Not only does Royal Bluematic offer quick results, but she also delivers aesthetically stunning flowers and relaxing body highs. This strain emerged after Royal Queen Seeds crossed the legendary cultivar Blueberry with a high-performing ruderalis variety. Thus, they took the best traits of this classic and made them much easier and faster to cultivate.

After placing her seeds in the soil, growers should be prepared to harvest her bud within a timeframe of 8–9 weeks. Such impressive speed makes her a great candidate for guerrilla growers looking to stay below the radar.

Royal Bluematic blooms colourful buds boasting shades of orange, green, purple, and yellow, as well as a THC content of 14%. Her phytochemical mix provides a stoning high augmented by sweet and earthy flavours.

FEMINIZED FAST GROWING STRAINS

Feminized cannabis seeds are designed to produce only female plants. Feminized seeds will produce a female plant 99.99% of the time. Don’t waste your time trying to produce flower from a male plant – they will only pollinate you females, resulting in seeds rather than bud.

Fast Flowering strains are hybrids of these and autoflowering strains. They are genetically coded to produce flowers quickly with little care, but still rely on a change in photoperiod to flower.

Some of our most popular selections in this category include:

CANDY KUSH EXPRESS

As well as offering a rapid flowering time, Candy Kush Express is a rich source of terpenes, emanating notes of sugary sweet citrus. Her speed of growth and incredible taste make her a great strain for cannabis chefs who want a crop that yields well on a regular basis. This strain features a close balance of 60% indica genetics and 40% sativa, which exerts an effect that relieves tension from the body while keeping the mind alert and functional.

Candy Kush Express is a speedy photoperiod variety that features a flowering time of only 7–9 weeks. Plants grown indoors under good-quality lights will yield up to 525g/m². Those grown outdoors are capable of yielding between 450–500g/plant.
