Insta Green by Grotek is the emergency revitalizer you need in your arsenal to instantly restore the lush green color of your plants. Designed to act fast, this supplement provides a direct shock of nitrogen and essential trace elements that eliminates yellowing and brings vitality back to your crop before you even panic.
Are you noticing that your plants are losing their shine and turning a pale, sickly yellow? It’s one of the most common nightmares for any grower: nitrogen deficiency or stress that stops development dead in its tracks.
If you ignore these signs, the problem won’t just go away. Chlorosis spreads, photosynthesis slows down, and your potential harvest starts to shrink by the minute. There is nothing worse than watching your hard work fade away because the plant can't absorb what it needs from the substrate.
The solution is Insta Green. This formula is designed to bypass root blockages and deliver nutrients directly through the leaves (or roots), turning your plants back to a healthy, vibrant green almost instantly.
Think of Insta Green as a defibrillator for your weed. Its main function is to correct nutrient deficiencies that cause yellowing, but it does much more. It acts as a powerful conditioning agent for the growing medium and is exceptional for preparing cuttings before rooting.
By containing chelated iron and calcium along with nitrogen, it ensures that the plant recovers its metabolic rate. It is compatible with Cannabis fertilizers from other ranges, although it works best within the Grotek family. Whether you grow in soil, coco, or water, this product is the safety net that ensures a stress-free cycle.
Using this product is simple, but you must choose the method based on the urgency of the problem. Here is how to apply it safely:
With foliar application, you can see a change in color and leaf "perkiness" in as little as 24 to 48 hours. Root application takes a bit longer but provides a more sustained effect.
Yes, but be careful. High nitrogen is not ideal for late flowering. Use it only if you have a severe deficiency and avoid spraying buds directly to prevent mold or taste issues.
Yes, Insta Green is a supplement, not a base nutrient. You can add it to your regimen if you see deficiencies, regardless of the brand you use, though it's optimized for Grotek charts.
I always keep a bottle of Insta Green on my shelf, not because I plan to use it every day, but because it's the best "fire extinguisher" when things go wrong. I remember a crop where the pH fluctuated wildly while I was away for a weekend, and the plants looked terrible—pale and sad—when I returned.
I did a foliar application of Insta Green at 15ml/L, and the next morning it was like a different garden. The leaves were pointing up and the dark green color was back. It’s also my secret weapon for newly rooted clones; a quick spray ensures they don't cannibalize their own leaves before the roots are fully established. If you want peace of mind, buy it.
