house plant hydrometer 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!

Fast paced romantasy you will not want to put down!
Format: Kindle
4.25 stars! I LOVED this book with similar vibes to Hush Hush, Fourth Wing, and The Serpent and the Wings of Night! It was fast paced with easy world building and will keep you turning the pages late into the night because you will not want to put it down! Huntyr is a fierce bad@ss FMC trained to kill vampyres her entire life. She is sent on a mission to go to the academy and earn her spot into The Golden City. Upon arrival, she is forced to room with the delicious fallen angel, Wolf, who is the only one who knows about her assassin identity. The romance, the plot twists, the secrets revealed, the battles, and the tantalizing training scenes had me hooked! And that ending…. I’m holding my breath in need to know hell! Read if you love: 🪽 Fae, Vampyres, Fallen Angels 🪽 Academy setting with magical trials 🪽 Forced proximity and slow burn 🪽 Rivals to lovers 🪽 Hidden identities and secrets 🪽 Tend your wounds “𝘖𝘧 𝘤𝘰𝘶𝘳𝘴𝘦 𝘐 𝘸𝘢𝘴 𝘸𝘢𝘵𝘤𝘩𝘪𝘯𝘨 𝘺𝘰𝘶.

Excellent Rivals to Lovers!!
Format: Kindle
The tension and banter between Huntyr and Wold was delectable. I absolutely love the fallen angel and all of his flaws. Huntyr is amazing too being a badass FMC with some major trauma. The world building was great and I enjoyed the training aspect of the story. The writing was immersive and was in the story the whole time. The ending had quite a twist that I hadn’t anticipated and made my jaw DROP. Excellent job! I also loved the narration. Laura is one of my fave narrators!

Fallen Angels, fae, vampires, oh my!
Format: Kindle
Rating: 4.5 | Spice: 2 (but a good slow-burn) • Main Characters: Huntyr and Wolf • I couldn’t wait to read this book; there was so much hype about it! And there was no doubt why. I fell in love with the characters and the plot itself. This book is mainly plot driven more than friction driven but it’s easy to follow along with. The characters are fun, easily understood. The main setting is at an academy where both the main characters are going through trials and building strength for the final test, The Transcendent. There are fantastic side characters as well. I loved the camaraderie between Huntyr and her friends. But we don’t like Lanson. 😆 We do have some plot twists that come into play throughout the book. Secrets and betrayal to be seen. I did adore Wolf and Huntyr’s relationship. It was a classic slow burn trope. They didn’t hit it off fast, but in time their feelings grew. I loved their banter, so sexy. Wolf is your next book boyfriend; Huntyr is your next vampire assassin independent bad-a*s female. Themes include loyalty, trust, self-discovery, a true slow burn romance. Side note: book ends on a angsty cliffhanger! • Emily, thank you for writing this awesome novel and I cannot wait to devour Book 2, Blood So Brutal! 😍 • Happy reading, my lovelies! xo

“My heart bows to you and you only, Huntress.”
Format: Kindle
3.5 🌟 This book popped up in my KU recommended reading suggestions and the synopsis sounded like what I was in the mood for. I'm so glad I took a chance on it. I went into this knowing absolutely nothing about it and ended up really liking it. I love when this happens. The main characters are likeable and I easily found myself rooting for them. There is a mystery element to each of their backstories that I enjoyed watching unfold and can't wait to get more of. Wolf, in particular, has me fixated. Love him. I found this to be an entertaining, addictive read with a plot that moves along at a good pace. It reads so easily I found myself very reluctant to put it down. Lots of twists and turns and the angst is there. A good set up for the next book to come, for sure. My issues with this book....the dialogue feels a bit juvenile at times and there is a repetitive over use of a particular word phrasing that I found myself giving the ole eye-roll to. There are, without a doubt, some pretty cliche moments that gave me a bit of the cringe. I think this could've certainly 100% benefited from more depth regarding the world building. Perhaps the world building was sacrificed to keep the pacing quick? Just a guess. Also, the lack of consistency of character for the FMC was really evident and so she feels quite illogical at times. Overall, this was a fun and enjoyable read that hit the spot well enough for me. That ending certainly has me impatiently pining for book 2!

Interesting take on the genre
Format: Kindle
True rating: 3.25 ⭐️ I enjoyed the fresh take on the genre. The best way I could describe the setting and world is an apocalyptic dystopian version of Farie where vampires, fae, and angles struggle to survive in what is left of the world. It was definitely interesting throwing the academy/hunger games aspect into this world as well. Even though I guessed the final reveal early on in the book, I kept hoping I was wrong, and it would take a surprising turn. While the "plot twists" were a bit predictable to me, I still enjoyed the ride this book took me on. Another downfall for me was the plot holes in the world building... I.E. if society has fallen and the world is in the aftermath of war, how are there trains running around the world? Just to take young adults to the trials to get into the golden city? How is the train maintained, the tracks clear, etc? However, I did enjoy the FMC & MMC and thought they were fleshed out nicely. I also enjoyed the side characters but wish some were developed more like Ashalin (sp?). I do find myself rooting for the MCs to succeed and find happiness together, which is obviously an important aspect for romantasy. Overall, was this an earth-shattering, mind-bending, terrific piece of literature? No. But was it the worst thing I've read this year? Also, no. This book has, to me, the bones of a great read & just needs a bit more to push it from an alright book to a great book. Overall ratings: Plot- 3.5⭐️ World building 3⭐️ Spice 2.5 🌶🌶 Main characters 4 ⭐️ Supporting characters 3.5⭐️
