Hydroponics Soil Mix, Grodan Rockwool, and Better Hydroponics Roots

Hydroponics soil mix makes a difference Hydroponics soil mix makes a difference

In a previous article we provided you an ideal hydroponics soil mix so you could make a recipe that works well in grow and bloom phase and can also be used with your hydroponics nutrients. Based on feedback from several hydroponics growers, here’s some additional insight into growing hydroponics crops using soil…

Grodan rockwool gives you that aeration, predictability and precision.

In many ways, the easiest and purest hydroponics gardening material for your plants’ roots is a sterile root zone media such as Grodan rockwool. If you’re going to use root zone media at all (you could use aeroponics or NFT and have no root zone media), you want total control over the N-P-K and other elements that enter your plants’ roots. Grodan rockwool gives you that aeration, predictability and precision.

But rockwool has no nutrients on board, so if you water with just water and no hydroponics nutrients, your crops are going to fail fast. One reason hydroponics growers experiment with hydroponics soil mixes is that they want something with at least a little onboard nutrition.

For example if you’re using Sunshine Mix #4 or Pro-Mix HP, you get a pre-made soil mix that starts your plants off with a cache of built-in grow phase nutrients. The cache is called a “starter charge.” It won’t last long; find out directly from the manufacturer how long it will last so you know when to start providing fertilizer to your crops during watering.

Also understand that unless you buy a fresh bale or bag of commercial soil mix, the starter charge may have deteriorated so that there’s hardly any nutrition at all in the mix. Be sure to check for expiration date when you’re buying products such as Pro-Mix and Sunshine Mix.

In the case of Pro-Mix HP, you get about seven days of starter charge nutrients and then you have to apply hydroponics nutrients along with your water. If you’re using a richer mix such as FoxFarm Ocean Forest, you might get up to 30 days of growth without having to apply hydroponics nutrients along with water. Always ask the manufacturer about this. You’ll find there are a lot of differences between commercial soil mixes.

Please be cautious about applying extra nutrients while onboard nutrients built into the commercial mix are still active and present, because you might overfeed. If you overfeed young crops, you burn their roots and they may never recover full function.

Creating your own hydroponics soil mix gives you the opportunity to test and adjust for the particular hydroponics crops you grow so you create a better root zone for your valued hydroponics plants.
On the other hand, if your crops have sucked all the onboard nutrition out of your soil mix, and you haven’t started a hydroponics nutrients feed program yet, your crops are underfed. Growth will be slow; roots will develop poorly. A stunted crop will be the result.

In the soil mix I described in a previous article, I went for a rich, varied, seasoned, aged, biologically alive recipe that will provide your crops with all they need to get through an entire season from start to harvest. Using that formula, adjusted to your particular hydroponics system and the strains of hydroponics plants you grow, you could just water with rainwater or reverse osmosis water adjusted to 6.0-6.5 pH, and your hydroponics plants would grow well and yield an adequate amount.

On the other hand, you can and should use hydroponics nutrients and supplements with that soil mix to amp up your crops, especially their bloom size and potency. Stay tuned for my follow-up article on using hydroponics nutrients and supplements with customized soil mixes, and check out this handy guide to creating your self-made customized soil mix. Creating your own hydroponics soil mix gives you the opportunity to test and adjust for the particular hydroponics crops you grow so you create a better root zone for your valued hydroponics plants.
