    My plants are dying! What to do?

    Victor. There is a lot of confusion on here regarding ph controller use. Or weather you should leave on for 24 hrs. The main thing to remember is to have the co2 steady and on constantly while the light period is on. How you achieve this is up to you. There is nothing wrong with using a ph...

    Why dose ferts daily if manufactures advise weekly?

    Interesting thread, i too have often wondered why ADA, tropica etc. suggest to add weekly, but if you follow EI you add 3 times a week or even daily. I personnaly belive there is no right or wrong way as long as you achieve the results you are after. Some people prefer to add daily, others...

    Possible EI Micro Mix Product?

    As Ceg says. Just work out how much to add to reach fe target level. If dosing EI you want around 0.5ppm fe. I'm sure one of the chemists on this site would work out how many mg per 100L of granules you would need to add. At a guess i would say somewhere around 600mg per 100l but you need to...
