If you grew in the richest, most unpolluted outdoor soil, your root zone would swarm with beneficial microbes that live symbiotically with your plants, swelling their roots and boosting harvests. However, hydroponic growing media are devoid of these microorganisms. That’s why you need Tarantula, whose beneficial bacteria promote other beneficial rhizospheric life. They also inoculate the roots, safeguarding them by competing with and warding off harmful bacteria that can infect plants. And they even reduce tissue damage from heavy fertilizer salts. What’s more, these beneficial bacteria directly increase plant growth and yields by releasing growth and bloom co-factors and aiding chlorophyll, so your high-intensity lighting is more effective.
