What’s good, fam? Today we gonna break down how tall them autoflower weed plants be gettin’. We talkin’ ‘bout all them dope strains so you can get a clear picture. Now, indoors, these lil’ greens can be as short as 40 cm if they compact or shoot up to a tall 160 cm when they outside flexin’. Even though they can hit them heights, they still mad compact compared to them feminized homies.
On the regular, autos chill around 65–105 cm indoors and 85–125 cm outdoors. That’s a mix of genetics, too, from them Sativa vibes to those chill Indica strains, coverin’ all the fams like Kush, Gelato, and Haze. Now, while some plants might go over these heights, it ain’t common. With the right setup, your autoflower plants should stay snug in that range.
Indoor vs Outdoor Heights
How Tall Do Autoflowering Cannabis Strains Get?
Autoflower strains be one of the most stealthy and compact genetics out there. They keep it small throughout their growin’ cycle and they speed through from seed to harvest way quicker than photoperiod strains. But how tall can these autos really get? Most of ‘em stay on the smaller side, but things like pot size, genetics, where they at, light levels, temperature, humidity, and a whole bunch of other stuff will decide how tall your plants get, ya feel me?
Usually, autos max out between 40cm and 160cm. They start off at about 5–10cm and grow a few sets of true leaves before they switch from seedling to vegetative stage. During the veg phase, these bad boys can grow around 5cm every day if you got their nutrients, water, and light just right.
Genetics play a huge role in determining how tall your autos get. Sativa-dominant strains be reaching for the sky, while Indica-dominant ones stay stout and bushy. For example, autos in the Sativa-packed Haze fam can stretch to about 100–120 cm before they flip into bloom, then they might stretch another 40–60 cm in flowering. But those Indica homies from Kush and Gelato families, they chill around 80cm before they start putting out flowers.
Check This Out: Average Sizes of Auto Strains
- Gelato: Indoor Height: 75–115 cm | Outdoor Height: 90–130 cm
- Haze: Indoor Height: 75–115 cm | Outdoor Height: 110–150 cm
- Cookies: Indoor Height: 75–115 cm | Outdoor Height: 85–125 cm
- Kush: Indoor Height: 65–105 cm | Outdoor Height: 90–130 cm
- Afghan: Indoor Height: 55–95 cm | Outdoor Height: 65–105 cm
Indica vs Sativa Heights
Now let’s break it down, fam:
Indica
Indica-dominant autos usually don’t get too tall, maxing out at 120 cm indoors and 130 cm outdoors. They perfect for them tight spaces, known for their fat, dense buds and sturdy structure.
Sativa
Sativa-dominant autos be reaching higher and skinnier, with indoor plants hitting up to 120 cm and outdoor ones puffin’ up to 150 cm. They can surprise even the pros if you ain’t watchin’ ‘em close.
How Tall Do Autoflowers Get Indoors vs Outdoors?
When you growin’ indoors, space be limited. Smaller containers mean tighter roots, but autos still hit max height even in modest pots. Untrained, Runtz Auto might grow to 70–100 cm, Haze Auto around 65–85 cm, and Diesel Auto could sit at 40–70 cm.
Outdoors? Whole different game. Plants usually grow taller when they outside. With more space and that sunshine, they can flex way more. If you wanna go big, think bout using raised beds or stick ‘em straight in the ground for them roots to spread out. Some autos be reaching up to 150 cm outside, like Cookies Gelato Auto hitting 140 cm, or Granddaddy Purple Auto peaking at 120 cm.
Pot Size: How It Affects Plant Size
Pot size matters, fam! The size of the root system below ground controls how big the plant can get above. Smaller pots mean smaller plants. Many growers find an 11l pot gives them good size and health. But if you want them autos to go big, a 20l or bigger pot is the move.
Factors That Influence Height of Autoflowering Weed Strains
Besides pot size, there’s mad other factors that impact how tall your autoflower plants get. Genetics is a major key, but light, planting density, and climate play a huge role too.
Choosing the right strain from jump can help control height later. For example, Cookies Gelato Auto might stretch big, but Triple G Auto could top out at 60cm if managed right.
Light is crucial for growth. Plants need that light to build their structure. When they lacking light, they stretch tall and spindly reaching for it. But when they getting enough light, they stay compact and strong. If you inside, make sure you on point with your PAR levels.
Temperature and Humidity
Temperature and humidity matter too. Keep it around 25°C for the best growth. If it gets too cold, plants stunt. And humidity helps with nutrient uptake, so shoot for 70% when they seedlings, drop to 50–60% during veg, and 40% when they flowerin’.
Tips for Managing Plant Height
Now that you know what influences the height, let’s get into some tips to keep your autos in check:
Why Autoflowers Are Perfect for Tight Spaces
If you only got a lil’ grow tent or a small balcony, autos gonna make your grow easier. They compact by nature, and modern hybrids still give you good yields with dope THC and terps. Pair the right strain, pot size, and lighting, and you’ll have a stealthy plant that fits your grow game.
So there you have it, fam! Keep these tips in mind as you navigate the world of autoflowers, and you’ll have a successful grow that’s dope as hell!
