Know before you buy
Yes, this liquid concentrate is suitable for both hydroponic systems and soil-based gardens. Because it is a liquid, it mixes easily into your nutrient reservoir, though you should monitor your system to ensure it remains well-circulated.
Roots Organics HPK is minimally processed to preserve the integrity of the bat guano and Langbeinite. While it is highly effective, it is not fully water-soluble, so it is best suited for hand-watering or systems that can handle organic suspensions.
You should introduce this bloom booster once your plants have transitioned into the flowering phase. The 0-5-4 NPK ratio is specifically formulated to provide the extra phosphorus and potassium needed to support heavy bud development.
Absolutely. Because it is CDFA Certified Organic and derived from natural sources like bat guano and Langbeinite, it is an excellent choice for vegetables, flowers, and herbs.
The quick-release formula means the nutrients become available to your plants almost immediately upon application. This allows for rapid uptake during the critical bloom phase, though you should follow the recommended dosage to avoid over-fertilizing.
