Nutrient companies that send out samples


Recommended Posts

Or if you want the chems

You can get all these items at a farm supplies place -Elders etc or Nursery.and from your purchase you will have more than enough for a decade or more.If you buy them in 20kg bags

Or share them with others in the purchase price 

NUTRIENT QUALITY

You’ll only get out of your homemade hydroponic nutrient mix what you put into it. This means you want top quality elemental salts. Purity in is a must if you’re going to have a great grow. The other super important thing is accuracy of measurement. It’s not a teaspoon of this and a cup of that. The salts are measured by weight, and an inexpensive food scale designed for kitchen use is not accurate. Find one designed for lab use. Never use improperly stored salts either. Any moisture they’ve absorbed will change their weights, which will affect your nutrient solution quality. They must be kept cool, and dry at all times.

HYDROPONIC NUTRIENT FORMULAS

These are basic, general purpose nutes – so if your goal is to tweak them, you’re on your own. They give you a good starting point no matter why you want to know how to do this, and have proven successful with many different hydroponic crops. The amounts in these formulas are for 1-gallon of stock nutrient solution. If you want a bigger batch, you’ll need to multiply and/or divide the measurements per gallon appropriately.

MIXING YOUR NUTRIENT SOLUTION

Start with an clean, empty container large enough to hold your full batch. Fill it with warm water. Test the TDS/PPM and pH before proceeding. The pH will change after you’ve mixed in the elemental salts… so don’t adjust it just yet. Make a note of both meter readings. You have to take the dissolved solids content of your water into consideration, because you need to subtract it from the final reading to find the true concentration of nutrients in your solution.

Now add your precisely weighed out elemental salts ONE AT A TIME, and allow it to dissolve completely before moving on. This is not a concentrated formula. At this point you are diluting it to the strength needed to go into your nutrient reservoir. Do not add it to your system until it has totally cooled. Let it sit for an hour or two before taking the next meter readings.

You may need to adjust the nutrient concentration and/or the pH before it’s right for your plants. Hopefully, you already know the EC or TDS/PPM, and the pH level your crop requires. If not, stop and research that, because if the pH is off, the plants will have a hard time accessing what they need to thrive. Even a simple, inexpensive liquid pH test and control kit will allow you to easily measure and maintain the pH level of your nutrient solution.
