Get the Most From These Beautiful Black Bottles!
Why go to all this extra expense and hassle? Because we’re growers, just like you. As such, we wanted to make the most user-friendly and stable hydroponic nutrient possible—one that truly performs brilliantly in a real-world scenario—not just in our laboratory!
The story doesn’t end there however. Once those beautiful bottles of Pure Essentials Black Label are in your hands, there’s plenty more you can do to really maximize the benefits your plants receive from all the initial care and attention we put into our products. So, without further ado, here’s Guy Green with SIX awesome tips for making the world’s hottest premium hydroponic nutrient go the extra mile (or pound!) for you!

TIP 1) Nutrient Reservoirs—The Larger, The Better If you’re recirculating your hydroponic nutrients—and we sincerely hope that you are—then you’ll be aware that factors such as pH, TDS, temperature, and plant waste levels are all subject to change. The best and simplest way to mitigate any potential adverse effects is to mix up your nutrient solution in the largest, practical res available. 50 gallons is usually enough for most hobby-sized grows, but there’s no harm in going for a 100-gallon beast or even more!
Guy adds: The dilution rates of our super-concentrated Pure Essentials Black Label VEG A & B and BUD A & B give you outstanding value for money—so don’t be afraid to go LARGE! You’ll save even money with our larger sized bottles too. Why not order securely from our online store?
Did you know that quality water is the most important additive you can put into your garden? The majority of indoor gardeners use their municipal water source (i.e. tap water) which can

TIP 3) Stay Chilled! 66 °F – that’s the magic number. Pumping nutrient solution along warm pipes sat underneath grow lights, then through growing media and root zones, and finally back into your reservoir can cause your solution to warm up into the 70s—causing dissolved oxygen levels to plummet. You may as well send a written invitation to the dreaded Miss Pythium to come and play havoc with your roots! Check your nutrient temperature regularly (certainly at the start and end of each light cycle) to monitor its temperature. Buy a nutrient thermometer from your grow store.
Guy adds: If your source water is chilly, use a nutrient thermometer to bring it up to that magic 66 °F. If—and this is more likely—your nutrients are too warm, invest in a chiller for a few hundred bucks. They really are a cheap insurance policy for your crop and an absolute must for media-less systems like DWC or NFT.
Some growers go as low as 5.2. Others 5.5. Others 6.0 to 6.5. So what’s it going to be? Well, firstly, let’s get one thing clear. You absolutely NEED to keep on top of your pH levels. So investing in a quality digital pH meter, calibration fluid, probe storage solution, and pH adjuster fluid is a must. But you know all this already! What you might not know is that we created Pure Essentials Black Label to be super pH-buffered. That means, as your plants feed off the pure, raw, mineral elements—your nutrient solution sort of auto-corrects, bringing itself back to optimum pH levels. This is a hallmark of a quality hydroponic nutrient and it’s what sets commercial blends apart from an amateur garage mix-up and other lesser brands.
Guy adds: I recommend the range 5.8 to 6.2. But hey—it’s pH stability that really sets Pure Essentials Black Label apart from the pack. We use multiple forms of nitrogen, phosphorus and chelated iron (plus more than a few other tricks!) to give you a nutrient that’s easy to adjust and maintain. The result? Your plants have 24/7 access to all the nutritional elements they need to fully express their genetic potential! You’ll see the difference in lush, vigorous growth in the veg stage and phat, bountiful blooms in the flowering cycle. For the optimal result, try Pure Essentials Black Label growing media too. We have two coco coir / perlite mixes “Perfect Blend” and “Essential Mix” and the ever-popular, double-washed, super sterile horticultural clay pebbles! What a supreme combo!


TIP 6) Bubbles, bubbles, bubbles!

Nothing keeps a nutrient solution happier than movement and oxygen. Use an air-stone connected to an air-pump at the bottom of your reservoir and bubble constantly, 24/7.
The increased dissolved-oxygen levels will help to turbocharge metabolic rates in your plants’ root zones—super-driving the nutrient assimilation process even more and helping to ward off those nasty pathogens that can decimate a crop in days.
