Good brand but don't use their recommended dosing, use half strengthGreat product, really rich nutrients. I have been using Botanicare nutrients for multiple plants and I have to say it's easy to work with and last a good amount of time I'm hydroponics before water need to be changed. If you start with tap water, after you add the nutrients PH level may be right on point. What I've discovered is water from the local windmill water source outside the grocery store, will bring the pH down to about 4.0 so PH up is a must for that. Hope this info helps a little. Thank youI have 6 hydroponic systems. I have used a competing brand in the past with no issues. This brand was recommended by the manufacture of a hydroponic system I recently purchased. The nutrients are composed of natural ingredients such as fish meal, composted seabird guano and rock phosphate. I really like that.The only major cons are it smells awful and I found it causes a brown gooey residue inside my hydroponic system. Therefore I have to clean more often.Major pros is my plants love it. The blooms are abundant especially on my tomatos and cucumbers. I also like the natural ingredients Botanicare uses in their line of products.I will use it for a couple growing seasons and see how it goes.Been using this brand for years. Results are impressiveSo far so goodpureThe product is a good product it's what it is my review is on the seller shipping speed is greatIt’s actually amazing stuff I’m running it vs GH flora and vs black magic and it is winning the contest ?Definitely would recommend.
