monstera plant moisture meter 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!

Excellent tug toy!
Size: Large Triple, Size: Large Triple
My dog had this set of 3 interlocking rings for 7 years and they finally broke. I was so happy to be able to get a replacement set that is just as durable as the original! Just ask our Gretzky to, “get your rings” and she knows exactly what to find. She can tug these for an hour and not lose interest. She loves them. They are the perfect size for her to grab comfortably and for her human playmate to hold onto the other ring in opposition. Gretzky is half Boxer, about 85lbs and all muscle. For her first set to withstand years of tugging without breaking was surprising but they’re made well and as long as you don’t allow your dog to just sit and chew them, they’ll give you years of tugging playtime!

Simple! Easy! All We Needed!!
Size: Large Triple
These were the only durable rubber like rings that were both the same material; not too thick (not heavy) so my 1 year old Pit, Dixie, was able to latch on to one ring while we grabbed the third ring, leaving enough space so she won't accidentally bite us when grabbing the rings to play. They were also the only ones that came interlocked and cannot be taken apart. She is also a big chewer, which means she can gnaw on these without tearing them apart. The rubber is thick enough to play, but thin enough to twist and flex with her. So far, they are sturdy. She was immediately so excited! Simple and easy!

Great durable dog toy!!
Size: Large Triple
We have a medium-sized dog (45 lb mixed Aussie/Hound) who is a pretty aggressive chewer. He also loves playing tug-of-war with his canine and human siblings using these rings. This is easily his favorite toy. We bought one a little over a year ago that he plays with daily. If finally broke this December just in time to buy a replacement for Christmas! The prior one finally broke when the middle ring came apart at one of the thinner rubber points. He still plays with the intact outer rings as well as his new toy. I wanted to dock this 1/2 star for a few reasons: 1) it is not completely invincible, although I would argue a toy that lasts over a year with pretty constant play for an $11 price tag is a great value. 2) the one we received is not yellow/black. It is blue/green. I was personally thrilled it was blue/green because it ended up being an exact replacement of the one we had previously. However the description does not say "colors vary" and it was hard for me to tell when ordering if I was ordering the correct replacement toy. A clearer description would be appreciated. 3) This is a great toy for one dog, but our other dobbie/cattle dog mix has no interest in them. So not all dogs will love this toy (obviously). 4.5 stars isn't an option so I'm giving this 5 stars because it's just about as close to a perfect dog toy as one can buy (at least for our dog).

Great toy, as long as dog is NOT ALLOWED to chew on it
Size: Large Triple
Let me start by saying that I like this dog toy. My big dog LOVES tugging with it. As long as you keep away when the dog is in a chewing mood, it lasts a long time (my 1st one lasted a year), however, it WILL NOT last if the dog chews on it, as I found out with this one. A friends dog chewed on it while she was behind a snow mound (mostly out of our sight) when it was only a week old. One end ring was barely holding together when we discovered her chewing it. Fortunately it was an end ring, so I still have 2 connected rings for tugging with. It is a great tug toy! But it is also a TERRIBLE chew toy, so make sure to take it away when your dog starts to chew on it and it will give you long service.

Fabulous toy!!
Size: Large Triple
My GSD is always up for a good game of tug-o-war. I purchased these in large and I think I love them as much as my dog. They are super strong and hold up to his 100lb self pulling on one end and my “blah blah-lb” self pulling on the other. (Ha! You thought I would say how much I weigh) I even bought another pair for our cabin so we have some to play with at both places. He isn't a sit and chew on things kind of dog. He gets plenty of playtime and bully sticks for chewing. Not to mention that I wouldn't let him use them as a chew toy anyway. There are toys for play and toys for chew. Therefore, I cant say anything on how they hold up for chewers. So if you let your dog just sit and chew on it instead of giving them something designed for strong chewers, then no it might not hold up to that. All I can say is my German Shepherd is 100lbs with sharp teeth and stronger than me now and honestly he is probably stronger than I have ever been in my life, and they hold up to the pulling and tugging of both of us. Thats what they're designed for and they serve their purpose excellently.
