Adjusting PPM

I am interested in trying to start my own hydroponics system and I have a question that may sound a bit silly.

I noticed after researching that many vegetables need to have different levels for optimal growth.

For instance, I want to grow carrots. What would be the best/proper way to increase the PPM to the suggested 1120-1400 ppm?

My first thought would be to mix the nutes as listed on the manufactures label according to the amount of water in your reservoir. Then to make increased adjustments should I mix more nutes to one gallon of water and slowly add to the reservoir checking the levels each time?

I am not sure really. I thought I would find out if there is a certain way of doing this that I may be missing.

Any other suggestions that I may need to know around this may help too. Such as if there is anything I need to know about raising the ec/cf level or other adjustments...

Thanks!

Answer from Stella/Simon:

Hi there Z,

Welcome to hydroponics, you'll find it rewarding, productive and fun! The question you ask is not silly at all, and perplexed me when I 1st got started.

There are charts available which suggests the proper EC levels for all the various hydroponic crops. And unless you plan to restrict your garden to just one specific crop at a time, you would wonder about this very issue.

At this website, we truly have simplified hydroponics for you. my advice is when you first start out, try not to worry too much about all the numbers. Just follow the directions for your nutrients. They usually specify certain mixing directions for new growth, growing and leafing stage and flowering and fruiting stage. Just go with the directions, and keep your nutrient vat fresh.

Later, if you want to get into optimizing the EC for your crops, just Google and you'll find charts to guide you. The method you described above is perfect for titrating to the proper concentration of nutrients.

Hope this helps!
