Product Review by Roy Stevens

Experienced growers will have heard of mycorrhizal inoculants but if you haven’t don’t worry, mycorrhizae in simple terms are small fungal filaments that work in conjunction with plant roots and assist them in absorbing more water and more precious nutrients.

Mycorrhizae are essentially nature’s natural soil inoculants and in addition to improving and sustaining hydration and nutrient levels, they also release helpful enzymes that help breakdown hard to digest nutrients into more suitable forms that are more easily utilized.

Mycorrhizal inoculants occur naturally in soil but can over time be depleted through a number of factors like chemical use, topsoil erosion, compaction, and even cultivation so it is extremely beneficial then to supplement their levels by purchasing and using readymade mycorrhizal inoculants.

Growing Needs

The first thing we need to consider is what exactly are your growing needs and why are you considering purchasing a Mycorrhizal Inoculant in the first place.

If you are hoping that a Mycorrhizal Inoculant will do all of the hard work of growing for you and you are certain to end up with healthier, stronger, better yields then you may be disappointed.

Mycorrhizal Inoculants are a soil amendment and a great assistant for helping plants grow quicker and more resilient and whilst it can increase yields there is no guarantee and you will still of course have to monitor your plants consistently to ensure that all the normal things remain in balance (pH level, hydration level, nutrient levels, etc).

If you are content with this and are looking for an amendment that can help improve your growing environment and optimize your growing conditions then a Mycorrhizal Inoculant may indeed be just the thing you are looking for.

Mycorrhizal Inoculant Ingredients

The next thing we need to think about is what is the actual makeup of the Mycorrhizal Inoculant itself and do these ingredients align with your growing ethics.

Many growers refuse to use products containing chemicals or GMOs and if you are one of these then it’s always important to thoroughly check a product’s ingredients to ensure that they meet with your personal approval.

We completely understand these reservations and as such all of the Mycorrhizal Inoculants we have reviewed here are completely natural and contain no harsh chemicals or GMOs for you to worry about.

That being said of course, often in this industry products which are made from one hundred percent natural ingredients and aren’t full of chemical additives come with a higher price tag, so be prepared to pay more to find a product that is suitable for your own tastes.

Product Size & Specifications

The size and specification of the product you are considering purchasing is equally important of course as it’s vital for you to get the right amount, not just so you can supplement your plants but also so that you don’t have to waste more time, effort and money reordering more Mycorrhizal Inoculants.

Always carefully check how much you need then our advice is to then add a considerable margin on as this will cover any unexpected shortfalls, accidents, or wastage that may then occur.

Many of the products we have featured here today come in various different sizes, weights, and specifications but you should remember that any difference in size to the specific product we have reviewed will inevitably lead to a difference in price.

Also, it should be remembered that these products are designed to be effective with minimal use meaning that it’s not necessary to overload the plant with Inoculants and that a little goes a long way.

Your budget will influence all of the above decisions and rightfully so, we here at The Highest Crop always recommend that you fix a budget firmly in mind prior to browsing products and we definitely recommend that you stick to this budget.

If, of course, you are lucky enough that your budget is not a concern then you will be more influenced in your purchasing decision by the above factors.

However, If you are keen to get the best price possible and get good value for money then it is imperative you stick within your budget and be willing to compromise on product specifics.

As with all things, the higher your budget is the more high quality and premium a product you will inevitably find yourself with.
