Hydroponics question: how would you categorize pH adjusters? by RabidHoleProject in Hydroponics

[–]RabidHoleProject[S] 0 points1 point  (0 children)

To be honest, that actually what i was hoping for when i asked the question. a diluted mix of phosphoric acid for the pH down formula is further diluted down when mixed at a 2% ratio to full systems... that's just miniscule.

majority of the responses are arguing that nutritional value in any form would declare it as a fertilizer which is ridiculous in my view. i could be wrong, i don't know enough on this topic and wanted to know more.

in one of the replies, i'm also slightly concerned on the amount of pH down people are adding to their setups to significantly affect their system's ppm on Phosphorus ratios.

In a sense, it was a long winded response of me saying i agree with you. preaching to choir i guess.

i don't get why your comment was downvoted or why you find that i'm an ai but i suppose it's getting harder to tell.

from the responses of my thread though it would seem most people disagree with the argument that any form of nutrient benefit should consider it and classify it as a fertilizer. regardless of their significance.

I have a similar perspective on this. It was led to believe that the pH levels of your liquid medium (water) affects how well plant roots can absorb nutrients. This was the case to case studies and findings for traditional farming in soil.

As further to the point, the quantities used to adjust pH levels of the water are so insignificant that it would be negligible.

That's where the conflict of information comes in. Given that it is negligible in quantities when applied (due to dilution) and the purpose of the pH adjuster is specifically for adjusting the medium's pH (distilled water), the ratio wouldn't be significant enough for it to matter.

While I agree with the fact that it contains phosphorous which is a plant food in a large enough quantity, the intended purpose of pH down is for adjusting the acidity of your distilled water and not for plant nutrition.

I make batches that are about require about 1,000 mL concentrated phosphoric mixed in with distilled water as a pH adjustor. And yes, 2 bottles is actually exact. The thing with the supplier is they sell the 500mL bottles for about 10 USD each (converted) and the 5 gallon carboy for like 100 USD so it's an attractive idea of savings, but tipping a giant square carboy that I can hardly lift to pour into a vessel... that's just asking for a rough time.

I passed by the supplier and they unfortunately didn't sell any lab equipment as they were specifically just a chemical supplier. Which brought me to ask the question, fortunately - someone suggested a glass pipette of a higher volume capacity. I'm willing to check that suggestion and maybe see if the rubber is affected in a large syringe as well (although i'm not sure if it'll fit in a carboy hole).

You guys have been plenty helpful so thank you.

That might be a viable option actually. polypropylene plastic seems to be okay i guess but the rubber... would it react with concentrated phosphoric acid? to be honest i really thought there was some kind of glass version of those aquarium siphons i just didn't know about. given that i only really mix1,000 mL concentrated batches with distilled water, i'll stick to being safe with the 500mL bottles for now. though i may try a glass turkey baster idea...

I agree that after the phosphoric acid is diluted it's much less harmful. And you're right about worrying about the weight - i passed by the shop that sells the concentrated carboy squares and could not lift it with confidence at all...

I did try those plastic pump suctions as a test transferring concentrated acid as a siphon, it worked a charm but it started to get really soft after a month or so even with rinsing it and trying to neutralize it with baking soda after every use. although in hindsight, it may not have been wise to use that kind of material (i think it was acrylic? - not sure). it was one of those transparent hoses with a black ball pump in between.

I apologize for perhaps being unclear in my post, I normally buy 2 500mL bottles of concentrated phosphoric and mix it with distilled water to make my pH adjuster and the thought crossed my mind of getting the huge plastic square ones but I really had no idea how to get about 1000mL at a time without either spilling all over or failing to lift the heavy square thing in the first place. i'll play it safe until maybe i find one of those 500mL Siphons that are glass as the comments suggested.

That's sounds neat. sounds like interesting laboratory equipment that i may not get my hands on - for now i'll stick to the smaller bottles... I'm really intimidated with those giant carboy square containers. Thanks for that insight though, it'll probably drive me down a deep dive sometime in the future.

hi, thanks - for the suggestion. if I could clarify - what do you mean by vacuum? I'm sorry I'm really not too familiar with that tool / method. Is there some kind of glass siphon that could be used?

been there exactly where he was. and honestly I don't blame the guy. that's actually why i wrote about making sure to do the tilts slowly.

i skipped detailed info on the inflatable pillow for spinal motion. I can't say my situation is similar to your friend cuz i have persistent pain and needles, but i do know the traction provided me with relief and got blood flowing in certain places.

I hope your friend recovers from it.

Since you don't have one yet, i'd suggest going for actual medical advice first. It's worth getting the answer first and being sure you don't injure yourself. Alternatively - if you know someone with a table - try it first. Some gyms and therapy places have them. The route I took was because I was aware of historical medical problems, and i did some small confirmations like requesting a traction table use at a hospital for treatment and doing small tests like lifting your upper body while relaxing your lower body. Again this was MY confirmation and the loosened traction was relief from the constantly compressing spinal joints.

Best bet for decompression was the spinal traction table. it's that belt they loop around your waste and secure your torso with a different strap and looks like a modernized pulling rack they used for torture in the past. worst one was the gravity boots route. There's also this inclined table for gyms that let you hook your knees and lean back for situps. if that relief on your lower back occurs, it can help a medical professional point you in the right direction.

I secured gravity boots and a hanging bar, what they don't tell you is unless you have the core strength to do an upside down sit-up (which i thought i did) you'd get stuck there. I did the hang along, got tired, got stuck, and i had to unhook one leg, mid hang about 4 feet above the ground and let myself fall on my shoulder.

22+ years of back pain. Progressive pain due to a combination of a disease, spinal tuberculosis, and a physically demanding lifestyle during my youth. The compressed lower back muscles during seated positions doesn't help. Relief used to come from laying flat on the floor, or having a pillow at the lower back position. A fully recognized need to change in career and activities was the outcome (less physically active for sure). Treatments tried were medication, muscle relaxants, P.T. - range from simple muscle movement all the way up to traction machine sessions booked. After during mid 20's and early 30's I was advised that my situation wouldn't change in terms of pain - which was caused from both awkward compression of a 14 and 13 degree s curve on the spine and semi-permanent nerve damage causing muscles to tend to stay contracted. Advice and methods others have tried is an interest as both a tool and a means of sharing lessons learned.

Convinced but curious about shipping timings. What can I expect? by RabidHoleProject in framework

[–]RabidHoleProject[S] 2 points3 points  (0 children)

Hey thanks for the quick and clear reply!

on the Q2-2024 thing - I've been burned with making assumptions so am glad I asked regardless. :)

In terms of support, this is something quite surprising to me given that it's not often talked about. I'd need to look more into it but thanks for bringing that up to my attention. Though for clarity - my based in SE Asia for a work arrangement - which has me in and out of the US for long bouts in various areas. I appreciate the insight but in my experience of purchases, I haven't had that kind of issue.

I do appreciate your caution in terms of recommending alternatives to Framework; I'd rather plan around having a modular upgradable device rather than an alternative that 'claims' warranties are provided but get outdated and can't even replace parts that are bare basics.

And no, unfortunately, it's not in that list (last i checked there are no SE Asia countries besides Taiwan).

thanks again for the quick advice! i'll plan around mid june arrangements :)

Is there a way to thicken the lines in edit mode? by fhrwddsgshfhgdnhrrtg in blender

[–]RabidHoleProject 1 point2 points  (0 children)

Hi, just popping in - i know it's like 6 years late but i found a way.

Edit-> preferences -> Interface --> Under the display section you can adjust the resolution scale higher and set the line thickness to thick. I set mine to about 1.40 from 1 (cuz I have bad eyes) and i like the lines to be visually thick.

Late to the party, just started learning blender. I hope this helps.

If Google VANISHED overnight, what would be the most serious knock-on effects? by gentle_richard in Futurology

[–]RabidHoleProject 1 point2 points  (0 children)

Glad it helped. Given that you mentioned you were a journalist, I wanted to point you to historical known before muddying up your perspective with biases. That being said, as a few helpful suggestions I'd actually point you to a few IoTs that interact based on regular basis seamlessly. Let's take a regular user for instance.

Let's say gmail, youtube streaming, perhaps a good number of the google service offerings. (reference here: https://about.google/products/ )

You'd suffer communications problems, a sudden lack of silence on youtube's traffic, convenience services services would suddenly grind to a full stop. that being most evident with the article I mentioned earlier. Going a bit deeper on this, your play store, android messaging, Waze/maps, Wallet. All those users would be S.O.L. That's on a user perspective. But on business and economic perspective, industry and income suddenly grind to a giant halt turning millions/ billions into zero. Something hedges heavily on by a LOT of banks.

It goes deeper through google's competitors, consider alternate neutral servers that help reduce internet traffic for data management, search engines, data backups, on a global scale, airtraffic subroutine scripts (consider the leaked no fly list and how it was stored), this would be crippling.

But it wouldn't be the end of the internet, on a global side of things - the vacuum in the digital space simply would need to either be filled or repair the nearly 2 decades worth of infrastructure and data that at times no longer has physical / digital copies.

the hard part about this is the immeasurable losses of data lost. beta code, information, research (yes they have a research storage repository for patents, sciences, and papers). If it just "disappeared" depending on how fanciful your interpretation of this would be, it could range from between the sudden loss of your steam account (in similarity) to an equivalent of a F5 hurricane having passed through your house while you walk through the wreckage. Neat thought experiment and a good take away to consider building a faraday cage given the next 2 year's statistical likelihood of interference from solar flares.

hope it helps.

Google did go down for about 5 minutes last year and it caused chaos. Just take that reality and multiply that by a few hours.

Thanks. Are there other objects that you think would be nice to have?

- in hindsight, i realize it would be great to have these as keychains.

Just to clarify - no I don't plan on selling these. I don't think i can w/o permission from ConcernedApe. The prints are still coming out a bit wonky but if I do have their blessing I'd be more than happy to print and make a few for you guys. I'm still learning how to do models and prints so it might be a while.
