Autoflowers are known for the ease of cultivation and the speed at which the plants grow into an adult and harvest-ripe plant. However, the disadvantage of a normal autoflower is the small size. That is different with this Big Haze. The Big Haze autoflowering feminized seeds grow into quite large plants despite their fast life cycle and produce a nice amount of weed. This makes the Big Haze Feminized autoflower seeds a very attractive choice for anyone who is looking for convenience, speed and high productions.

Growing Big Haze autoflowering feminized seeds

The Big haze consists for 70% of Sativa, 10% Indica and 20% ruderalis, which gives this plant the ability to bloom automatically. Growing Big Haze autoflowering feminized seeds is therefore very easy. Moreover, due to the short life cycle you have a limited chance of top rot. In addition, the plant has a high mold resistance.

This unique Haze hybrid needs a maximum of 11 to 12 weeks to grow into an adult plant. During growth she produces slightly more leaves compared to normal Haze. However, this is a ruderalis property. After the 11th or 12th week you can start harvesting. The Big Haze Autoflower produces a modest but high-quality harvest of about 150 grams per m2 that you will certainly appreciate. Especially because of the little effort.

The size of the plant is easy to control. If you put the plant in the open ground, outside in a sunny spot, the plant can reach a height of 150 cm. Is space limited, do you grow indoors or use a 12 liter pot? Then your plant will be about 60 cm high.

What kind of flavors, smells and effects does Big Haze provide for weed?

Big Haze weed contains a high THC content. This gives you an energetic feeling combined with a mild effect on the body. As with almost all other Haze species, you will experience exotic flavors and smells.

    I think my first order didn’t passed customs so i reached out and Frank shipped a new order free of charge which was delivered after 13 business days. Much much much appreciated Frank! Haven’t started with my grow but thanks a million for your awesome service

    Very suitable for beginners who like to grow a proper Haze strain. Clear Sativa growth but not to tall so I think it would be possible to grow this one indoors as well.

    I am a completely newcomer and this was the first time I have grown a cannabis plant. I must say …. I am already addicted to it. It is great to see this plant grow, and that with great ease. My own grown weed tastes better than I expected and I’ll be back soon to order new seeds.

    The Big line autoflowers from is just perfect. Normally my autoflowers didn’t yield that much but the big autoflowers actually do. Besides i love the simple way to grow the plants and the fast shipping was really good.
