Micro. By Emerald Harvest. 

There’s a common myth in indoor gardening that it’s all about the NPK - those three big letters that dominate the back of every bottle on the shelf. And yes, nitrogen, phosphorus and potassium are crucial, but if you think that’s the whole story, you’re missing the real magic. 

Emerald Harvest Micro is the unsung hero of the nutrient world, quietly delivering the sort of trace elements that separate average grows from those truly worth bragging about. Developed by Californian experts who actually understand what plants need - not marketing departments - this isn’t just plant food. This is molecular-level engineering.

Packed with Small Stuff.  Big Difference. 

The clue is in the name. Micro is absolutely packed with the small stuff that makes the big difference. Copper, molybdenum, iron, zinc, sodium, cobalt, manganese, boron… all the bits most people don’t think about, and all dosed precisely to fuel the intricate processes that keep a plant not just alive, but thriving.

These are the micronutrients that regulate enzymes, drive metabolism, and fend off deformities, discolouration and premature decline. And when used as part of Emerald Harvest’s 3-part system - alongside Grow and Bloom - Micro becomes essential, turning your nutrient regimen into a complete, balanced diet.

Dense Growth & Thicker Canopies.

This isn’t just a scattergun approach to fertilising. Emerald Harvest Micro offers the highest nitrogen content of the trio, making it a cornerstone for vegetative success. Nitrogen is the foundation of protein synthesis, which means lush, dense growth, thicker canopies, and accelerated cell development.

Add to that its inclusion of potassium to aid nutrient flow and starch production, and you’ve got a compound that doesn’t just nourish - it empowers. Micro doesn’t shout about what it does. It just does it better than anything else.

Made In California. 

Flexibility is where Emerald Harvest Micro shines. This isn’t some rigid formula you follow blindly. It’s a dynamic, responsive solution, built to adapt as your crop evolves. Yellowing leaves? Step up the Micro. Stunted growth? Time for a tweak.

Whether you're running a stealth cupboard in a city flat or an industrial-sized hydroponic installation, this nutrient fits into your routine and lets you respond to what the plants are telling you. From seedlings through to the final flush, there’s a dialled-in dosage that supports the entire lifecycle.

Stronger Structures. Healthier Leaves.

And let’s not forget calcium - the macro mineral that often gets overlooked in the rush to pump phosphorus. Emerald Harvest Micro contains calcium to reinforce cell wall structure, helping your plants build themselves from the inside out.

This isn’t just about feeding what’s visible; it’s about constructing resilient plants at the cellular level. Stronger structures, healthier leaves, and significantly better disease resistance are all by-products of proper calcium management. Micro delivers that in just the right amount, without the risk of overloading.

For the Flavour Hunters.

Ultimately, Emerald Harvest Micro is that rare thing in modern horticulture: a product designed by actual growers, not marketing executives. It’s formulated for those who understand that greatness in the grow room isn’t about flashy branding - it’s about results.

And with Micro, the results speak for themselves. From day one to harvest day, you’re giving your plants the building blocks they need to do their job properly. No fluff, no filler. Just solid, science-backed performance in every drop.
