It achieves this through two technical pillars that work together \u2014 absolute homogeneity and maximum reactivity.<\/p>\n<p>Homogeneity means that every bag behaves identically: the same water distribution, the same air-to-water ratio, the same root environment across the entire growing row. Reactivity means the substrate responds rapidly and predictably to irrigation decisions \u2014 draining when you want it to drain, retaining when you need retention.<\/p>\n<p>Together, these properties translate into a substrate that genuinely amplifies the grower&#8217;s steering capacity. ULTRA does not compensate for irrigation errors \u2014 it makes the effect of every decision visible and consistent, giving the grower real data to work from.<\/p>\n<div class=\"bgart-quote\">\n<p>We built ULTRA because we were seeing the same problem repeatedly in the field: growers making the right decisions, but the substrate not responding consistently enough to make those decisions count. Homogeneity is not just a quality criterion \u2014 it is the foundation of crop steering.<\/p>\n<p>    <span class=\"bgart-cite\">Biogrow Agronomy Team \u2014 R&amp;D Centre, India<\/span>\n  <\/div>\n<h2 style=\"text-transform:uppercase\">Engineered at our innovation centre \u2014 with data, not assumptions<\/h2>\n<p>  <!-- IMAGE 2 --><\/p>\n<figure>\n    <img decoding=\"async\" src=\"https:\/\/bio-grow.com\/wp-content\/uploads\/2026\/05\/ultra-rd-india.jpg\" alt=\"Biogrow R&#038;D centre in India \u2014 daily substrate monitoring\" class=\"bgart-img\" \/><figcaption>At the Biogrow R&amp;D centre in India, substrate performance is monitored daily \u2014 from irrigation volume and frequency to EC and pH drip vs. drain.<\/figcaption><\/figure>\n<p>ULTRA was not developed on paper.

We are seeing strong root colonisation from the first weeks, and drainage behaviour is behaving exactly as expected \u2014 stable and consistent with the R&amp;D centre data. Our technical teams continue to monitor these crops closely as the season progresses.<\/p>\n<p class=\"bgart-keyphrase\">Strong root colonisation, consistent drainage stability, predictable reactivity \u2014 the early field data confirms what the R&amp;D phase showed.<\/p>\n<h2 style=\"text-transform:uppercase\">Is ULTRA the right choice for your crop?<\/h2>\n<p>ULTRA is built around high reactivity \u2014 which is a genuine advantage for growers who use active crop steering strategies and want to drive vegetative or generative shifts with precision. However, high reactivity also requires a well-calibrated irrigation strategy. The substrate will respond fast; the grower needs to be ready to work with that speed.<\/p>\n<p>Every crop and every greenhouse has its own dynamics. Before integrating ULTRA into a production system, it makes sense to discuss your current irrigation approach with our technical team \u2014 not because ULTRA is difficult to manage, but because adapting an irrigation strategy to a more reactive substrate from the start avoids any unnecessary adjustment period mid-season.<\/p>\n<p>As the season progresses, we will continue collecting yield and quality data from the trial network and will share results as they become available.<\/p>\n<p>  <!-- FINAL CTA BLOCK --><\/p>\n<div style=\"background:linear-gradient(145deg,#004d4e 0%,#006465 55%,#007a7c 100%);border-radius:10px;padding:48px 52px;margin:56px 0 36px;box-shadow:0 10px 40px rgba(0,100,101,.22);\">\n<h2 style=\"text-transform:uppercase;color:#ffffff!important;border-bottom:1px solid rgba(255,255,255,0.22)!important;font-size:20px!important;margin-top:0!important;padding-bottom:16px!important;margin-bottom:26px!important;\">Discuss ULTRA with our technical team<\/h2>\n<p style=\"color:rgba(255,255,255,0.88)!important;font-size:15.5px!important;margin-bottom:18px!important;\">ULTRA is now available.
