You want to keep your water temperature between 60 and 68 degrees when working with nutrients.
Get a PPM meter. PPM means parts per million and describes the concentration of minerals and nutrients in your water. Keep your PPM level between 900 and 2800
Your hydroponic grow system is a bit more delicate and bringing in organic components might lead to difficulties or infections. It is best to stay with the chemical version.
Make sure to understand how to set up hydroponics system through reading our article on water management. You will be adding all your nutrient to the water so setting up this system is the first step.
Best pH for hydroponics systems is between 5.5 to 6.5. Don’t start adjusting too much when in the range of 5 to 7.
Start with a simple and complete marijuana product. Go half of the recommended dose and take it from there. Your hydroponic grow system will reward you when being gentle.
A solution with a low ratio of nutrients is a supplement and not a base nutrient. You do not really need supplements. Don’t burn your plants with an overdose.
The basic rule is: you want to keep potassium high and phosphorus medium to high throughout vegetative as well as the flowering phase. On the contrary, you will want to keep nitrogen high in vegetative phase and low for flowering phase.

Hydroponic nutrient solutions will be labeled with a N-P-K ratio. A label might read as 10-5-5. Which means 10% nitrogen, 5% phosphorus and 5% potassium. Nitrogen fosters growth. Phosphorus encourages growth of roots and flowers. Potassium promotes growth of roots and photosynthesis.
When growing without soil, nutrients will be a crucial factor to consider when trying to achieve the best yields possible. With the right combination, you’ll be sure to get the best buds in terms of quantity and quality.
These are all decisions you’ll have to make on your own, independently of what you read. No matter your level of experience, you’ll always run into problems that will likely require your intervention. This is how you learn. Just don’t let the death of a plant demotivate you or stop you from trying again. Hydroponic systems have the potential of yielding ridiculously potent, high-quality buds. The effort will pay off.
With so many brands and combinations of nutrients out there, which one is best for your grow? This is an important decision, but one you’ll be learning more and more about as you go. Only experience will help you assess the correct nutrients for your situation. It all depends on what you’re trying to achieve. But here are a few pointers to get you started.
With hydroponic systems comes the obvious advantage of having more control over what the plant is absorbing. Having constant access to water and oxygen, you just have to control which nutrients you give your plants, and in what amounts. But using this more experimental system can also detract from some of the beauty of growing weed in a traditional way.
There are some nutrients that are more easily absorbed by cannabis roots than others. Independently of the nutrient brand you choose, your plants can still face deficiencies if the pH is not correct.
Are you sure you’re using the correct products for your hydroponic system? These will differ quite significantly from soil solutions. Make sure you know what to use, and in which quantities.
In hydroponic systems, nutrients tend to be better absorbed when the pH around the root zone is between 5.5-6.5. But the ideal value you should aim for is 5.7. When looking to dial-in your pH, don’t necessarily trust a pH-stabilising solution. This kind of product still requires your constant attention. You’ll be better off flushing your system every now and then before purchasing pH-adjusting products.
The debate between growing in soil vs using a hydroponic system continues to unfold. We assume you’ve already made the difficult choice and are ready to commit to your method. Once the commitment is established, you’ll have to make the decision of purchasing the best products for your situation. These will depend on personal preference, level of experience, and commitment to the grow operation. You might prefer nutrient solutions that require less attention, or you might be looking to control every single factor that can influence your yields.
In hydroponic systems, the nutrient solution you choose will replace the micro and macronutrients that soil would normally provide. The advantage of hydroponic growing, however, is that you can replicate a soil medium without the unpredictability.
