📦Scope of delivery of the FermentBox® complete sets
Application - Gentle drying, currying & fermenting
With the FermentBox® Drying Box & Curing Box you achieve a Slow, controlled drying, which reduces the risk of mould formation and at the same time protects the complete terpene profile and the characteristic flavour of your flowers.
Through the Super Silent ventilation system with activated charcoal filter the air is moved evenly and unwanted odours are reliably neutralised. The regulated environment with a relative humidity of 60-70 % ensures an ideal balance between gentle dehumidification and natural maturation.
During the first two days, the filter runs continuously; from day 3, a timer control (3 x 10 minutes per day) is sufficient to maintain a perfect microclimate. From day 5 onwards, a moist bowl or the ProFerment powder can be used to keep the humidity stable.
Compared to conventional drying methods, the FermentBox® also enables the Degradation of chlorophyll, which makes the flowers noticeably milder and sweeter similar to the tobacco refining process. The result is High-quality flowers with improved Aroma and flavour.

Unfortunately I had to wait a long time for my box, but I was still able to pull out the blossom. Nothing smells so far, I'm looking forward to the result!
Vanessa Berens -
I think the FermentBox is a great innovation and exactly what I need. However, in my opinion it is a bit too expensive.
Oliver Becker -
Does what it says on the tin, my cabbage tastes delicious and there was no odour during drying!

I use the box because I don't have any drying facilities in my flat without the whole flat smelling of broccoli. So far I haven't noticed any broccoli odour, the box absolutely fulfils its purpose. I'm looking forward to the final result.

I dried my first grow with it, had the best buds ever after two weeks, and the rest of the harvest, which was allowed to stay in the box for four weeks, was really exhibition ripe! The second grow will be dried soon, I've ordered the optional items and I'm looking forward to seeing how it turns out, I'll keep you posted! Oh, and about the smell: the fan is so quiet that I thought I'd forgotten to switch it on. All you can smell is the good pine wood that the box is made of.

My box arrived today. Very nice customer service by e-mail, very fast delivery, everything went very well. Now it's time to get the buds in

The box arrived in perfect condition and well packaged. The delivery time was acceptable. The box is made of pine wood and is impeccably finished. The installation of the activated carbon fan system was self-explanatory. This is inserted on the inside, the centre shelf has to be pulled out for this and is calculated so that the fan fits flush with a slight gap. The drilled hole for the ventilation connection piece (has an external thread and a matching outer ring, which then fixes the fan inside when screwed onto the connection piece from the outside) and the separate cable feed-through are a perfect fit, the cable feed-through has a rubber connection piece with a cross notch and closes well. The front sliding board for loading and closing the box is designed so that a ventilation gap remains, it is easy to move, but should be handled with a lot of feeling. The pine wood is untreated. I decided at my own risk to treat the outside of the wood with a wood wax certified for children's wooden toys. I have used this sparingly, the breathability of the wood structure is guaranteed, I have been using this wax for many years and have experience with it.
The optional accessories, the bowl and the Pro Ferment powder that are included in the delivery make a good impression on me.
The WLAN thermometer and the WLAN timer wasted two hours of my precious time last night and are not suitable for my WLAN router, or are cheap Chinese scrap - please respond to my return request!
I bought a wifi socket with a timer function from Hama today, which was installed within 5 minutes and works perfectly with a good app. Now we can get started, the herbs will soon be ready for harvesting!

Hello, we're sorry to hear that. Please don't put too much in the box at once. If the box is quite full, leave the activated charcoal filter running 24 hours a day for the first 5 days.

Hi Alexander, 200g wet weight is 40g dry weight. They actually fit in easily, without any problems 🙂

In this case, it is better to leave the fan running permanently for 5 days. But you don't have to pre-dry the buds 🙂
