indoor plant water gauge PlantDoc Moisture Meter - Mini MonsteraWhat is PlantDoc? You've just found the world's first and only 100% biodegradable, plastic free moisture meter. Meet PlantDoc. Saving lives, one plant at a time. The favourite tool of over waterers, under waterers and worried plant parents. Just what the (plant) doctor ordered to help solve your water worries. How does PlantDoc work? PlantDoc is a colour changing moisture meter that stays in your plant's pot, monitoring the moisture level at a glance.

What is PlantDoc?


You've just found the world's first and only 100% biodegradable, plastic-free moisture meter. Meet PlantDoc. Saving lives, one plant at a time. The favourite tool of over-waterers, under-waterers and worried plant parents. Just what the (plant) doctor ordered to help solve your water worries. 


How does PlantDoc work?


PlantDoc is a colour-changing moisture meter that stays in your plant's pot, monitoring the moisture level at a glance. No more guesswork. Pop it in a dry plant, white side facing out, and water as usual.


PlantDoc changes colour in response to the wet soil and the pattern appears. Your PlantDoc will slowly return to white as the soil dries out and it's time to water again. Simple!

What is PlantDoc made from?


PlantDoc is made from 100% biodegradable, compostable, sustainably-sourced plant-based fibres with non-toxic hydrochromatic colour-changing ink.


When it's ready to replace, pop it in the garden or your compost and PlantDoc completely breaks down with no residues. Safe for curious hands and paws with no harmful dyes or chemicals, making PlantDoc pet safe and kid safe. No batteries required.  

 

What comes in the box?


One box includes 5 PlantDocs, enough for around one years supply for one plant. One PlantDoc lasts one to six months each (depending on your soil type and watering frequency), so one 5 pack lasts from 5 to 30 months all up. All for just $4 per PlantDoc.


Sustainable, safe, non-toxic, biodegradable AND budget-friendly, a win for plants, plant parents, pets and the planet 💚


What substrates work best?


It might seem obvious, but because PlantDoc absorbs water from the substrate, which makes it change colour to tell you when to water when it dries out again, the substrate makes a difference. If your substrate barely holds much water, PlantDoc won't have as much water to absorb, and won't give as clear readings. That means fine to medium grade substrates with medium to high water retention work best.


Substrates with very low water retention can still work to some extent, but you won't get as accurate readings (like chunky or bark-based substrates), so they aren't the best match for using PlantDoc. No different than other water meters. Chunky substrates don't work well with any water meters. 


How to read PlantDoc


PlantDoc will change colour when wet and slowly return to white as the soil dries. You can decide when to water based on how dry your plant prefers to be.


MOIST

Peace Lily, Maranta, Stromanthe, Fern, Aglaonema, Anthurium and similar


For plants that like to stay lightly moist and are prone to dry leaf tips and margins if left dry for long, water again when PlantDoc is about 1/4 to 1/2 dry*


PARTIALLY DRY

Monstera, Philodendron, Fiddle Leaf Fig, Scindapsus, Epipremnum, Pothos and similar

For plants that prefer partially drying out before watering again, water again when PlantDoc is around 3/4 dry*


FULLY DRY

Hoya, Peperomia, ZZ and similar

For plants that like to fully dry between watering, water again when PlantDoc is fully dry*


DRY FOR A WHILE

Cacti and similar

For plants that love dry conditions for a while between watering, note when PlantDoc turns fully white and water again lightly in a couple of months* 


*Remember ALL moisture meters are only a guide, not gospel. They don't know what type of plant they're in. Moisture meters can only tell you what the moisture level is where they are in the plant, not when to water. You still need to decide when to water according to your plant's needs and your conditions. Moisture meters are a tool to help you read the signs. Don't ignore your plants other signs they need water, such as wilting.


How long does one PlantDoc last?


Although it does depend on how often you water and your type of soil, one PlantDoc normally lasts to 6 months. However (based on my own plants and watering habits), I found it was more around 1 to 3 months in my conditions.


In general I find for plants in a finer soil or plants that prefer to be maintained lightly moist (like a Peace Lily) it'll last shorter, vs plants in a grittier or chunkier mix that like to dry out fully between watering like Succulents and Cacti, where PlantDoc will last a lot longer. PlantDoc also 'reads' moisture better in soil types that are finer or hold more water.

Water your plant, not your PlantDoc! That can shorten its life. PlantDoc breaks down faster in always-wet, finer, more compact soil and lasts longer in drier, aroid-type potting mixes and with plants that prefer to dry out between watering.


When do you change PlantDoc?


You'll know when it's time for a new PlantDoc to take over when your PlantDoc no longer changes colour within half an hour of watering.


PlantDoc is also a great alert for pests and to help protect plant roots, as soil pests like fungus gnat larvae will chomp on your PlantDoc instead of your plant's roots. 


Why does PlantDoc turn brown?


Over time, some types of soils might stain your PlantDoc a brownish colour. More common with new soil or peat-based soils and new bark that have a higher tannin content. The same reason some plants turn drainage water yellowy-brown when you water them. Don't worry, that won't change the performance of your PlantDoc (but you can always change it early for the aesthetics if it does bother you).  


How does PlantDoc compare to other moisture meters?


All moisture meters have their pro's and con's but it can help to compare them to make the best choice for you and your plants. PlantDoc is the only fully biodegradable, plastic-free moisture meter in the world (patent pending).


SUSTEE

The closest type is Sustee. They also last a similar time, they also change colour, but Sustee is made of plastic (the core inside is partially compostable once you remove the plastic parts). PlantDoc is fully compostable and more budget-friendly.

Sustee cost between $16 and $22 per plant with refills around $8 to $11 per plant. PlantDoc are less than $5 per plant. Sustee do have 3 different sizes the largest size makes them better for deeper pots. PlantDoc is best from small to medium pots and measures the top 2 inches / 5cms of soil. Sustee are better for deeper pots. Like PlantDoc, Sustee don't work as well in chunkier substrates.


DIGITAL MOISTURE METERS

Unlike most digital meters, PlantDoc requires no batteries and can (and should!) be left in the plant. Digital water meters need to be moved from plant to plant manually to find out the moisture level. PlantDoc stays in the plant. 


3 IN 1 METERS

PlantDoc is more accurate than 3 in 1 type water meters with probes and gives you an immediate reading as you leave PlantDoc in your plant. The metal probes that 3 in 1 meters are made from erode in water so must NOT be left in plants, and need to be removed, cleaned and kept dry between use.  


PlantDoc don't last forever (I get 1 to 3 months use in my plants), but are fully biodegradable and 100% plastic-free. Good for our plants and the planet!

After ***TOO MUCH*** Research
After ***TOO MUCH*** Research The Amazon ad for this product is so ambiguous that I thought I should do some research before taking this supplement. After AN HOUR AND A HALF of googling, for information I've decided to give this 2 stars. Initially, I was thinking 4 stars (that would have been 5 stars, but I'm not happy about all the googling I had to do about the ingredients), but I decided to lower it because after a great deal of research, I'm still not sure if I should take the label's full recommended dosage, or something lower. But I'm going to start here with the positive: The main things that convinced me to order it it is that it's made in the USA in an FDA registered facility that is GMP certified. and it's 3rd party lab tested. But even though that put my mind to rest about production, the ingredient list is ambiguous, and since there's no Medical Recommended Dosage, I want to know what a safe amount to take is. The ingredients and amount of the supplement provided are MUCH too ambiguous label says that 3 caps provides 1800 mg of organic turmeric (cucurma longa root), and 150 mg of turmeric 95% curcuminoids (cucurma longa root). So what's the difference between these 2 ingredients? And what does it mean, anyway? I read down the entire page, and at the bottom the Product Description notes that "each serving delivers 1950mg of turmeric curcumin, standardized to 95% curcuminoids". But that doesn't explain much. Does that mean that the entire 1950 mg is curcuminoids? Why are the amounts listed sepaerately in the ingredient list? I googled for information about the different ingredients, but I'm not sure how to interpret it. Here's what I found: * A page on the NIC (official US government site) notes that "curcumin is a major component of turmeric, and the activities of turmeric are commonly attributed to curcuminoids (curcumin and closely related substances)". * Another NIC page, noted "In Curcuma longa, crude extract curcuminoid makes up 1–6% of turmeric by weight, distributed in 60–70% curcumin...whereas commercially available curcumin contains about 77% in curcuminoids." * On a page for a vitamin company (not the manufacturer/distributer for this particular product), I read "Curcumin 95 is a botanical extract from turmeric root spice. Curcumin 95 contains 95% curcuminoids." But the label is so confusing. Does that mean that 95% of the entire "1950mg of turmeric curcumin, standardized to 95% curcuminoids" is the amount in 3 caps? Or is it 95% of the 150 mg of the turmeric 95% curcuminoids, listed as an ingredient? And what's a safe amounts to take. The results vary a lot. A page on the Arthritis Foundation site says, "In one small randomized controlled trial, twice daily doses of either 250 or 500 mg of curcumin were compared to placebo. Both doses significantly outperformed placebo on all measures." This site also recommends taking a supplement that includes black pepper (as this does) "for better bioavailability".

Turmeric curcumin & black pepper
These capsules come in a freshness and safety sealed bottle. They’re pretty large, but the vegan cellulose capsules swallow easily with a little water. A serving is 3 capsules, You really smell the black pepper extract and turmeric when you open the bottle. The suggested use is to take them 20-30 minutes before a meal.

This is a good one
I really like these for inflammation reduction. That means a more comfortable, more pain-free body. I feel less achy when using these and that helps me through my day. They don't need to be taken (by me anyway) every day. These generally keep the aches and pains beat back so I have more comfortable movement and feel the effects of getting older noticeably less. They just help me feel generally more healthy.

"Solid credentials and nice presentation"...
The product presents as a professional well made product. The site page could be improved a tad with details just to match up with the product received. "FDA registered" is a requirement so it's not an over-and-beyond move. However, GMP certified and 3rd party lab tested are and are nice pluses. Capsule size is MEDIUM. MG per capsule is 600 MG or more based on the label which is pretty good. Black pepper is known to aid in absorption so you always want to see that with turmeric and some other supplements that benefit from its addition. Made in the USA is great. Ingredients are sourced domestically and globally. It would be nice to know where they come from outside of the USA. This is a very solid option for turmeric.

Add these if you like to keep things moving 😉
Size: 81 Count (Pack of 1)
The taste is good but not great lol I take iron and sometimes it makes me a bit constipated so adding these to my everyday keeps things moving. No side effects. Easy chewing sometimes they clump together in the bottle but a good shake gets them apart.
