Hrrrrm, no. Ink is like about 98% water, and the difference in formulation between companies won’t make that much difference.
Pen caps have different designs, and some caps seal more air-tight than others.I think you’ve got the right idea using a plastic tub.
It may be overkill, but there humidity control packets from a company called Boveda. Serious collectors of things like cigars, marijuana, and certain types of tea use Boveda packs to keep their stashes in good condition. For pens you could use something like this inside your tub, and it should keep everything from drying out.
Parts List:
64qt tub from Fred Meyer ($12)
Bag of Pearlite ($5)
Humidifier ($20)
PC Fan ($10)
Timer x 2 ($30) - I am upgrading to some sort of sensor controlled set up, where I don't need to mess with scheduling for optimum condition.
Construction:
1 hole on lid for in take fan, one hole in middle for humidifier, and 2 half inch holes behind lion's mane for exhaust (opposite end of intake fan toward bottom of the box) . I didn't use an exhaust fan, because positive pressure from intake fan is enough to push out CO2 floating on the bottom.

Use this, and just attach a tube on the top, and stick the other end into your grow space.
I splurged on a Miro washable humidifier, and it turned out to be so great that I bought a second one.
When youre watering give the plant a good soak so that all the soil is wet !
When the water goes to the bottom of your pot the roots will reach down further too that,ll give you good root development.
with your temps and fan the soil will dry out fast
I usually give my plant 500ml water every feed sometimes a bit more then leave it for 2 or 3 days ,but my temps are lower than yours and I dont use a fan as big as yours so our enviroments are different.
Next watering dont be afraid to soak your soil
Ive been looking on amazon for humidifiers myself was looking at getting this one for my next bucket build
Your humidity will be perfect for when you get to flower so I doubt you,ll be buying a dehumidifier
This is the one I have

I use these to add humidity to the cards
Boveda 58% Humidor Packets - 2 Way Humidity Control Packs - Size 67-1 Count - Cigar Humidor Accessories - Humidity Packs - Relative Humidity Packs - Humidor Packet - Boveda Packs Humidity Controller https://www.amazon.ca/dp/B01M7O0S3Y/ref=cm_sw_r_apan_glt_i_SNWN0SVX1E8H2M74W7H1
I have a glass tupperware I use , I set the pack on the bottom and then I used a mini wood easel and lay it flat on top of the packet and the card on top ( https://www.walmart.ca/en/ip/simply-mini-easel/6000196064591) any thing that keeps the card from touching the packet but allows air to flow will work. 2-3 days works then I double sleeve and that lasts a few months until it dries out.
If your card takes this shape "n" you need increase humidity (boveda pack) If your cars take this shape "U" you need to reduce humidity (silica packets)
When the boveda pack dries out, it feels "crunchy" you can soak it by leaving it in the sealed Tupperware for a week or so with a small container of water (it will reabsorb humidity)
Got this for the baby, love it ! Just a very dim red light. Very minimal and completely silent. Lasts for at least 15h with one fill

Yup! I got the Levoit for my personal health and later donated it to the plants. I've seen it recommended elsewhere for plants and apartment botanist on insta said it's her fav. Only downside is that it puts out a ton of vapor so it's gonna warp my shelves but whatever, my plants are happy. The little white one is from Amazon and I'm very pleased with it. I have to fill it about every other day, but I appreciate the size and it lasts long enough on intermittent. here's the lil guy The black one is for essential oils, from Target. It doesn't hold much water or put out much vapor and I have to fill it daily. I don't recommend it but I couldn't be bothered returning it.
The one I had is no long on Amazon but this one looks similar, just fill it back up when empty and you are good to go. I have mine set to high all the time. With the size I fill it up once a day.
I don't really use a good dehumidifier so I will be on the market soon as well.
I bought, but haven’t used yet, the following, it’s 2 for less than $13.99+5% Discount, BUT, these from this Seller seem to be Hit or Miss on if they work or not, BUT if you have an issue, You can always contact the Seller vis Amazon, and if it doesn’t work out like you want/replace or refund, then You can always contact Amazon and ask them to refund you..just sayin, just “in case”..bcuz I don’t want you to buy it and it not work out or you be unhappy 😁👍🏼

We just use a cool mist one, I think it was $35 or so at target? Nothing fancy at all. Just a dial on the front so you can turn on/off and set how much output you want. (It does have auto off which is good so the machine shuts off when it runs out of water instead of burning the unit out.) Has worked fine.
For us the biggest pain is cleaning it. I hate cleaning humidifiers. It has to be done so you don't cause bugger health issues by breathing in mold/mildew etc. Still a pain. But I have yet to have one that's NOT a pain to clean. And doesn't leave you wondering if you really cleaned it well enough. (I always use distilled water which I do think helps.)
I did lots of searching and the one below seems to be very easy to clean but it's over $150 and that seems steep for what it is. I am still considering buying it bc it does seem easier to clean than what I have but who knows.
Good luck!
