    Bottled DIY C02

    As its not the first time its been mentioned, heres how I did my bottled set up, I stuck it in plants as that seems most appropriate

    I bought a this regulator , this nut and tail , I got the bottle off him, a 12Kg bottle for £20, which I picked up off him - hes in Nottingham. To regulate the C02 you really need a Clippard MNV-2 needle valve and the tube adapters (I have a few spare) this valve costs about £8 I think, I managed to get mine for free, cannt remember the name of the company I got it from though....
    As for the defusser, you could use the one from a Hagen DIY kit or a JBL one or use this Its Plantbrains design, so has to be worth looking at.
    Apart from the above, you will also need some silicon tubing, not the white cheap stuff as you will leak c02 using the wrong tubing.
    When you turn it on, the regulator only needs a tiny bit of C02 going though it and use the needle valve to fine tune it



    *edit*
    OK, a year on and the bottle has run out, struggled to find a refill or a replacement bottle, so I contacted a fire extinguisher wholesaler and bought a reclonditioned 2kg bottle for £20, you should be able to get one from most suppliers, just ask them when the bottle was made though as the one above was made in 1966 and shouldn't be used anymore.....
    Heres a pic, all you do it remove the tumpet, wrap ptfe tape (69p from a DIY shop) and screw the regulator mentioned above onto it. When you squeeze the trigger, the pin can be re-inserted into the handle so it stays open. Just make sure the regulator is closed when you squeeze the trigger or you will loose all the c02 and the bottle will fall over

    Heres the bottle and regulator, I think the bottle has got to be good for a year and will (I think) cost about £20 to fill, its been running since Jan/Feb this year and still has 800 psi in it!!

    The pressure will remain fairly constant as long as the bottle has a little bit of liquid CO2 in it - the best way to see how much is in it should be just to see how heavy it is (this is based off theory not practice!)

    By a JBL defusser for around £14 from the LFS, they can order them, or use the DIY Hagen rack, there is an option of using a powerhead, depends if you want to go down that road though (as I mentioned above )

    Thanks Paul, have still to venture into the world of fast plant growth via Co2. Bit scared of it really, not sure why though, think I may have read a story about it's capacity to explode. It also sounds a bit "manly" sorry girls.

    but certainly will refer to this when I take the plunge

    Spoke to a company this morning and was quoted....

    1 x Clippard MNV-2 -- £9.70 net

    1 x 11752-1(pack 10) -- £7.00 net (10-32 x 1/8” i.d. tube)

    T'is a real pain as the adaptors are supplied in packs of 10. Figured the quote might be of interest to some anyways.
