Emerald Harvest pH Up and Down are very concentrated and very pure. They provide a very consistent and accurate formulation that growers can depend on.
Most growers, whether commercial growers or hobbyists, won’t need pH Up or pH Down. If they’re using the core Emerald Harvest product line, without any outside supplements or competing products, then in most circumstances they won’t need to adjust the pH. Our base nutrients and four core supplements are pH balanced already—and formulated to stay that way when used together.
But if growers mix in products from competing lines, or if they use certain growing media such as rockwool or coco coir, they may need to apply pH Up or pH Down to get the nutrient solution back in the sweet spot. Supplements such as Sturdy Stalk may also throw off the pH.
