How should i germinate the seed?

Hello, thanks for asking. You can check our recommended germination method and several others in our germination guide here: 2fast4buds.com/news/germinating-guide-for-autoflowering-seeds .

Hi Fast buds, I plan to do a session this winter and I risk having cool temperatures (10/15 degrees). I've seen that this SourD is cold-resistant. I also own Grapefruit, Blackberry, GSC, Smoothies, Cheese, Purple Lemonade Orange Sherbet and Blue dream. Which ones resist the cold by sourD and Blackberry? Thanks in advance:)

Hello, thanks for asking! If you're growing in 10-15 celsius you should grow Smoothie Auto and Grapefruit Auto.

is this a good strain for fibromyalgia?

Hello! A couple of clinical studies have shown that synthesized THC works well in providing relief, so it's likely that'll work. If you're not a cannabis consumer and don't want to feel the effects of THC you should look for balanced 1:1 CBD strains such as our CBD Crack.

any specific feeding schedule for this strain?

Hello! You should feed according to what the manufacturer advises and if you see signs of overfeeding decrease the dose a little bit.

I want to do SOG method with this strain (it's my favorite since the 90s!), I have a 4x4 tent, how much light should i use and how many do you think i should put in there? please help!

Hi! Yes, our Sour Diesel can grow up to 120cm so you'll need to do some LST such as a trellis net or tying down the branches, this way you can fit around 4 plants, if you don't want to do LST you'll only be able to fit 2 plants. The wattage depends on the number of plants you're growing, you need around 100w per plant.

does this strain give you the munchies? I have appetite issues and want something that will make me eat.

Hello! Yes, some studies suggest that THC enhances appetite so it could work, remember that the effect can change from person to person. If our Sour Diesel didn't have the effect you wanted, you can also try with our Girl Scout Cookies, Pineapple Express, and OG Kush.

hey fast buds, I've been growing this for about 40 days and tit's still not showing signs of preflower, is this normal? is there somehting I can do to push it to flower?

Hello! Yes, it's normal, some phenotypes can take a little longer (or less) to start flowering, as long as you are providing good conditions she will start to flower naturally.

how can i guarantee to get 21 % thc?

Hello! As long as you grow under proper conditions and provide the nutrients your plants need to grow your buds will have 21% THC.

does this make you sleepy?

Hi! Sour Diesel may make you sleepy but it isn't the best choice, we recommend OG Kush, Blackberry, and Northern Lights if you're dealing with insomnia or are having trouble sleeping.

How long are the effects of the sour diesel?

Hi! It's hard to say because it depends from person to person but our Sour Diesel's effect are definitely long-lasting.

How well does this strain do outdoors? I'm in australia and the season is starting soon I wanna get some going asap.

Hi! This strain performs very well outdoors, especially in hotter climates, so you shouldn't have a problem at all.

Is it better to use LEDs or bulbs like HPS or others with this strain?

Thanks for asking! As long as you provide 100w per plant it doesn't matter which one you use but have in mind that some LEDs emit the whole light spectrum while light bulbs don't.

Description

An easy to grow and hardy strain growers of all levels can appreciate. High in THC levels, reaching 21% with the world-famous fuel, citrus, sandalwood, and pine flavor that comes with this vintage Sativa dominant hybrid. Despite her Sativa influence, flowering time will only require 9-10 weeks from seed to harvest, making her ideal for growers who want classic, overpowering, pungent, sour terps in a short time frame. She may grow as tall as 120cm in height and will produce long, stacked buds typical of Sativa Cannabis. Her effects are energetic and clear-minded, that over time will develop into a dreamy focused buzz. An excellent choice for commercial growers and hash makers and extractors.

Original Auto Sour Diesel is a sativa-leaning autoflower bred from a classic Sour Diesel cut crossed with FB Auto #1, refined into a stable F4 feminized line. The goal behind this pairing was to preserve the unmistakable fuel-driven terpene profile of Sour Diesel while improving resin production, structure, and autoflower reliability.

Plants grow 90-120 cm with medium internodal spacing and strong lateral branching, producing elongated, dense buds with sharp calyx formation. Flowers are heavily coated in greasy trichomes that release intense gas, citrus, and earthy spice aromas on contact. Indoor yields reach 450-550 g/m², with outdoor plants producing up to 200 g per plant under good conditions.

Terpenes are bold and old-school, blending sour citrus, pepper, sandalwood, and earthy diesel notes. With THC levels up to 21% and abundant resin across buds and trim, Original Auto Sour Diesel is well suited for extraction, delivering pungent concentrates with strong flavor carryover.

With a 9-10 week flowering window, Original Auto Sour Diesel performs best when given space and light, rewarding growers with uniform plants and resin-heavy flowers across indoor and outdoor setups.

First FB Grow

The Sour D has been a pleasure to grow. When running automated drain to waste in half gallon containers, Grogu likes to keep the plants as short and compact as possible. Grogu topped the Sour D at the 2nd node, and out came an effervescent smelling bouquet of rock hard nuggage.
