pH and TDS Meter Combo Include:
pH meter *1, TDS meter *1, pH calibration buffers *3, user manual *1
Various Applications:
The Mars Hydro pH and TDS meter combination can be widely used to test data in hydroponics, aquariums, drinking water, pools, and other liquids with quickly stabilized readings.
Accuracy and Measurement Range:
The measurement range of pH is (0 - 14), with an accuracy of 0.01. The TDS meter reads 3 different data with an accuracy of 2%, the measurement ranges are - TDS (0 - 9990 ppm), EC (0- 9990 μs/cm), and Temperature (0.1 - 80.0 ℃ or 32.0 - 176.0 ℉).
User-Friendly Features:
The lightweight body provides portability and the LCD screen provides backlighting so that users can easily read the numbers even in dark environments. Automatic temperature compensation ensures correct and accurate readings at different temperatures. "Hold" buttons on the pH and TDS meters lock readings for easy checking and recording. Both meters automatically turn off after 2 minutes of non-use to avoid battery waste.
4 Display Modes Of TDS:
The Mars Hydro TDS meter can read 3 different data (TDS, EC, Temperature) and switch between 4 display modes (TDS+Celsius, EC+Celsius, TDS+Fahrenheit, EC+Fahrenheit), so that growers can have easy access to the exact data they want.
Calibration of pH Meter
: Mars Hydro TDS & pH meter combo includes 3 pH calibration buffers to help growers calibrate the pH meter when it has been used too long or too often. Add the buffers separately to pure water, then insert the pH meter and press, then the pH meter will automatically calibrate itself. (Detailed tutorial in the user manual)
Notes:
*Avoid water or solutions above the immersion line when you use the meters.
*pH and TDS meter readings can be stabilized quickly within 5s, but it takes 3 to 5 minutes when reading TDS of pure water.
*Be sure to clean the meters with distilled water and put on the protective cap after finishing the operation.
*There is no need to calibrate the meters too often, as they are already calibrated before packaged.

Gentle and Effective Daily Fiber Support
Size: 500 Count (Pack of 1)
Gentle and Effective Daily Fiber Support
I’ve been taking these NOW Psyllium Husk Capsules for a few weeks now, and they’ve been a reliable and gentle way to boost daily fiber intake. Each capsule is easy to swallow, and I like that they’re vegetable-based, non-GMO, and free of unnecessary additives. Unlike some fiber powders that can be gritty or hard to mix, the capsule form is super convenient—you just take them with a full glass of water, and there’s no taste or texture to deal with.
I noticed improvements in regularity within the first week, without any harsh cramping or urgency that some fiber products can cause. These really help with digestive comfort and maintaining a steady rhythm. One thing to keep in mind is that you do need to take several capsules per serving to get the full fiber benefit, so the bottle can go quicker than expected if you’re using them daily. Drinking plenty of water is a must with psyllium, otherwise you may feel some bloating.
Bottom line: A clean, effective, and easy-to-use source of daily soluble fiber that supports gut health and regularity. Great choice if you want the benefits of psyllium without the hassle of mixing powders.

This is magic on earth.
Size: 30 Count (Pack of 1)
These pills are actual magic. It’s not a placebo. I genuinely feel so much more calm and relaxed when I take one of these. It takes about 30 minutes to kick in, and I immediately feel my anxiety ease away. I usually take them on a stressful day or when I feel uneasy. They don’t upset your stomach, but you will be burping the smell of lavender.

As a healthcare professional, extensively studied this supplement. It's one of the best available in market to treat Generalized anxiety disorder along with other subthreshold anxieties. It really worked for me. Far better alternative to SSRI and benzodiazepines.
