Review: Compared General Hydroponics to Biopharm - (Note: Similar review under the Biopharm version as this is a comparison) A lot of people struggle with measuring pH and there are a lot of potential reasons such as pH pen drift, incorrect or inconsistent calibrations. I've sure tried to kill more than my share of plants chasing what I thought was a correct pH. I've also tried the strips, but old eyes, slight color blindness, and tiny squares don't play well together. So, I've moved to the pH drop tests and the plants are loving the correct range. I had initially bought the Biopharm 5.0-8.0 range drops and was comparing the results against the Biophbarm printed label. It was doing ok, but I was still getting some leaf issues here and there. Most of the variance was me not being able to compare the difference in the results to the label colors well enough. As I was looking for better measuring, I came across an image in the product description that I missed the first time around. This was the last image in the product details and showed 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, and 8.0 pH color spectrum results that were perfect for me to compare against. I added that image to my phone and use it to set my pH on target every time. MUCH better than the printed label. Based on now being able to dial in my pH on target every time, I'm giving this a 5.0 since it's much easier with the Biopharm image. I have attached that image to this review in case it ever disappears from the product page. While looking at the reviews for test drops, I saw a number of concerns about the General Hydroponics using needing to use 3-5 drops with the Biopharm using only 3 drops. So, I bought the GH as well to compare and found that both the General Hydroponics and Biopharm versions performed equally well - as long as you ignore the printed label (see 3/5 drop comparison image). The General Hydroponics printed label colors are colorful, but were less than useful to me. The Biopharm label wasn't as far off as the GH label, but both add in additional 4-color printing issues. So, even though I thought I was comparing correctly against the label, both the label and my pen were off (see pen measurement pics) and the plants suffered because I believed the pen more. When I did my direct head to head test of the General Hydroponics and Biopharm against the same water source, I found the most equally consistent comparison to be 4 drops of the General Hydroponics and 3 drops of the Biopharm (see 3/5 drop comparison image). I've included an image of the 3 to 5 drop test. You can see the General Hydroponics is just a little darker but is the same hue. Remember that you are looking for that difference in hue, not the difference in lighter/darker. The lightness or darkness of the color is a result of how concentrated the indicator agent is - nothing more [more or less]. Of course, you could use more or less drops if that helps you tell the difference. I am 5-star happy with both the General Hydroponics and Biopharm. You can see how far off my ph pen was in the 3rd image. Definitely time to recalibrate or replace my pen. tl;dr: Both the General Hydroponics and Biopharm tested equally well for me. Ignore how light/dark the results are; it's irrelevant. Compare against the hue (shift from redgreen). Use the pH color spectrum image instead of what is on the bottle. ## Features - Ph Test Kit - Contains pH Test fluid and test strips - One fluid ounce ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BT32UA | | Best Sellers Rank | #21,382 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #35 in pH Test Strips | | Brand | General Hydroponics | | Brand Name | General Hydroponics | | Customer Reviews | 4.7 out of 5 stars 1,838 Reviews | | Global Trade Identification Number | 00793094015158 | | Included Components | Hydrogalaxy | | Item Type Name | 1-Ounce | | Item Weight | 0.11 Pounds | | Manufacturer | General Hydroponics | | Material Type | Plastic | | Ph Range | 4.0 - 8.5 | | Recommended Uses For Product | Hydroponics pH Test | | Sterility Rating | 4.0 - 8.5 | | UPC | 793094000000 400100013434 877707810863 793094015158 | | Warranty Description | Warranty | ## Product Details - **Brand:** General Hydroponics - **Manufacturer:** General Hydroponics - **Ph Range:** 4.0 - 8.5 - **Recommended Uses For Product:** Hydroponics pH Test - **UPC:** 793094000000 400100013434 877707810863 793094015158 ## Images ![Ph Test Kit, 1 oz - Image 1](https://m.media-amazon.com/images/I/61iNZVdn1SL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐ Better than digital *by M***T on March 29, 2026* Good product, accurate. ### ⭐⭐⭐⭐⭐ Compared General Hydroponics to Biopharm *by N***S on April 7, 2024* (Note: Similar review under the Biopharm version as this is a comparison) A lot of people struggle with measuring pH and there are a lot of potential reasons such as pH pen drift, incorrect or inconsistent calibrations.
