Autoflowering Seeds From United Strains Of America - Order Auto Seeds

Choose autoflowering hemp seeds to grow and harvest your buds in as little as 10 weeks! Producing hardy plants which do not conform to traditional lighting cues, autos blossom all year round and provide multiple growing opportunities.


If you are looking for a fast-growing, user-friendly type of plant then look no further than our range of autoflowering seeds. Guaranteed to produce a respectable yield in a short space of time (typically a vegetative period of just 2-4 weeks), autoflowering seeds can be sewn year round for multiple harvests and an overall bumper yield. 

Autoflowering seeds are created by weaving light-independent traits into the biological make-up of a photoperiod plant. 

Here at United Strains of America we offer autoflowering varieties of some of the most popular strains from around the world. Working with carefully-selected, professional breeders who cross strains with the hardy, highly-stable native  ruderalis, offspring retain the best characteristics of individual strains but enjoy the significantly shorter growing time of their native parent. 


Opting to grow autoflowering seeds comes with some distinct advantages over growing regular, feminized or fast-version seeds. Here are a few advantages of buying autoflowering seeds from United Strains of America:

High yield, short grow time: on a plant-for-plant basis, 'autos' ( from autoflowering seeds) cannot match the production of 'photos' ( grown to a traditional light-dark cycle). However, the fast-growing characteristics of autos mean you can grow several batches through the year, exponentially increasing your annual yield!

Beginner-friendly: a short grow time equals a less labor-intensive cultivation. Autoflowering seeds are a great choice for beginner growers because they make for a less complex grow with fewer chances of stress or injury to plants.  

Simple lighting schedules: unlike other types of seeds, autos do not require a complex lighting schedule. Autos will follow a single schedule to maturity (usually 18/6) when you simply switch to a suitable lamp for the flowering stage.

Small is beautiful: one of the defining characteristics of autos are their compact stature. With most plants not even reaching 2 feet (23 inches), they are ideal for growing far from prying eyes in small spaces, such as grow cabinets.

Higher levels: developed from the wild-growing ruderalis, autos contain slightly higher levels than other types of . For growers and smokers who prefer a more lucid high or want for medicinal purposes, autos make a good choice. 

Bumper buds: maturing rapidly, with a compact structure and short lifespan, an auto plant can only produce a small crop. However, harvesting several times a year transforms a small yield (100-250 grams of buds per plant) into a bumper crop of up to four times that amount. This far exceeds the estimated yield of a photoperiod plant.


Here at United Strains of America we know there are some best practices to get the most out of your autoflowering seeds.

Best-known for user-friendly growing and harvesting, autos pretty much look after themselves. However, there are some top tips for getting the most out of your seeds. 

For great results, follow these top tips:

1. To get the most from your plants and discourage mold and disease, create a growing environment where the temperature ranges between 68-86°F and the humidity is no more than 40-50%.  

2. Avoid high-stress training methods and injury to plants. Autos struggle to recover from stress and injury, more so than other types of plants, resulting in a poor yield. However, low-stress training (LST) techniques can be used carefully and sparingly to improve auto yields. 

3. The small stature and hardy nature of autos means they require less nutrition than other types of plants - take not to overfeed! 

4. Take a considered approach to harvesting by removing the top colas first. This allows the lower, less developed buds to enjoy some more light and to mature fully before you harvest them.
