Thank you very much for your help. Cheers.

Thank for threads and reply to related query about calculating ppm. Thank" grizzman" for your help.

Hello,

I think it would be better if you focus on 1 plant first since your setup is still small because it would simplify it and would give you more space to analyze the results.

Reg. your question, try searching the web for ppm calculator. I think there is one called hydrobuddy that is free

I'm an Electrical Engineer with a strong background in Electromagnetic fields and used to design telecommunications equipment for Motorola. Plants respond favorably to the right EM fields and yields and vigor can be improved greatly by generating a simple field around the roots with either a simple battery or by pulsing the field with a flashing circuit. Bi-phasic fields work best. The voltage level must be appropriate for the plant size.

I live in Hong Kong and am looking for a good supplier for liquid nutrients, pH meters and grow lights. I'll be happy to share my expertise ....

I love gardening. I built two hydroponic system, NFT and DIT in my small balcony. I been successfully grew cucumbers, peppers, strawberries, herbs, beans, choi sum and various vegetable. Before I bought my hydroponic nutrients from U.S. but too expensive and cost too much in freight charges. Now I do my own nutrient solution and would like to share with people who has the same interest. I have all my pH/TDS meters, chemicals etc. locally. I live in Hong Kong and Shenzhen.

Hi Guys,

I know it's an old thread, but did you succeed in finding nutriments locally ? I'm in Kowloon and want to grow some veggies & fruits on the balcony, but no one at the flower market was able to understand what I was looking for.

Hi I just came back from Kowloon, and there is a Hydroponic shop close to the wet market I dont know the street but I bought some seeds there and they have lots of supplies, this shop is close to where all the tropical fish and gold fish are sold sorry best I can do .
I was staying in the Mongkok area and was only a short walk as I was staying at a large hotel across the road from the flower market

Try this address I think it was the one I visited all in Chinese so I cannot read.Best of luck let me know how you go.
