I definitely have a book somewhere that describes the plants & methods the Victorians used.I don't think you need to open up the tank at all, the plants are producing C02, I have certainly left my tanks for weeks on end completely sealed.
The Victorians were very keen on bottle gardens & some fern displays were corked for years on end, so nothing new here LOL.
It is an "acid carboy", they used to be popular for bottle gardens, but are in short supply these days as conc. acids are stored in smaller containers now.I don't see any reason why a large sealed bottle couldn't remain green for at least 40 years.think the container shape plays a big part as it allows the condensation to form & drip, that guys appears to be using some type of acid storage bottle
cheers DarrelOn this second voyage, they successfully collected 2,126 breadfruit plants and hundreds of other botanical specimens and delivered them to the West Indies. The slaves on Jamaica, however, refused to eat the breadfruit, so the main purpose of the expedition was ultimately a failure. However, breadfruit is today a staple in Jamaica.
I had a look a while ago for a green tint one, but there weren't any locally. They were from about £25.Available in clear & green tint, you could see them lying around the derelict vinerys but, now all the glasshouses have gone along with the carboys! I am going to put out a plea on our locale EBay to see if I can get one or two...
You'd do it tomorrow if you had the chance, I know I would 😉I'd like to point out I was about 10 at the time).
