45 Day Autoflower Seeds

What are 45 Day Autoflowers?

45-day autoflower seeds are pretty much what it says on the box; that is, any autoflowing weed strain that takes around 45 days to complete its flowering cycle. This is exceptionally quick, as most autoflowers take anywhere from 55 to 75 days to form their buds, depending on the strain and growing conditions.

Autoflowering strains have become increasingly popular in the past decade due to their fast growth, how easy they are to cultivate, and their ability to produce huge yield numbers in less than three months. Keep in mind that the 45-day figure only relates to the flowering stage of growth, so the full lifecycle will take longer than this when the germination and vegetative growth stages are taken into account. Most autos switch from veg growth to flower production around 25 to 30 days after the seeds germinate.

These types of autos are ideal for growers seeking a fast turnaround, as they transition from seed to harvest in a significantly shorter period compared to traditional strains.

How long do 45 day auoflowers take to grow from seed?

Most 45 day autoflowers take around 55 - 70 days to grow from seed to harvest. Autoflowers tend to start flowering within 2-4 weeks of vegetative growth so the quicker your plants starts flowering the faster it will finish. There is no set time that autos begin flowering which is why the window can be slightly different for each strain.

What is the Fastest Growing 45 Day Autoflower?

Naming the fastest auto in the world isn't the easiest task, as new strains hit the market daily.

But, right now, Lowyder 2 is among the fastest-growing 45-day autoflowers. Known for its rapid vegetative growth and compact size, Lowryder is the perfect choice for those who want a quick harvest without sacrificing quality. It's super-efficient at producing top-shelf, frost-covered, dense as the day is long nugs making it a prime choice for those chasing a fast-finishing autoflower option.

How Much Can You Yield from an Autoflower in 45 Days of Flowering?

The final yield is dependent on the care and attention you give your plant, the strain you choose, and the cultivation style you decide to work with.

Indoor growers running a hydro setup will often see the best results, as this growing method allows for higher yields in less time. But that's not to say you can't produce huge numbers with outdoor-grown 45-day autos; it's just that you are at the mercy of the elements a little more.

Generally, growers can expect to yield around 2 to 4 ounces per plant from a 45-day autoflower. With that said, experienced growers who have all the important details dialled right in can easily push the 6-ounce mark.

The overall yield also depends on how well your plant performs in the vegetative stage. Plants that are offered the right balance of nutrients, light, and water during the veg stage will have built a solid foundation that allows them to produce much more bud during the flowering stage.

Growing Tips for 45 Day Autoflowering Strains

If you are looking to push every last drop of green goodness out of your autoflowering crop, there are a couple of things to keep in mind.

• Timing - Outdoor growers should wait until the climatic conditions are perfect before planting their 45-day autos. As these plants take less than 3 months to go from seed to harvest, it's best to wait until the last week of spring before germinating to ensure the best sunlight exposure.
• Plant Training - The last thing you want to do is to be heavy-handed with autos, but you can employ some light plant training. Running your crop under a SCroG net, or with the Sea Of Green (SoG) method, will help increase the yield.
• Nutrient Management - Generally speaking, autos don't need as dense of a nutrient feed as photoperiod strains, and this is especially true in the first few weeks of their life. If you're new to growing autos, it's best to read up on that particular strain and see how other growers have done by checking grow dairies.
• Lighting - Autos can grow on up to 24 hours of continuous light. However, they perform best when grown on a 20/4 or 18/6 light schedule. You do not need to change the light schedule to trigger flowering. Outdoor growers should look for a growing spot that receives as much direct sunlight as possible.
