Organic soil and RO water

What do you mean "they dont have any available"? Amazon shows it as in stock for me.
I'm mainly looking for something subtle I can put into my RO water for daily watering in between nutes, so the 0 PPM water doesn't deplete them of anything. Can your Bloom booster be used for that purpose? Looking at it.
Iron: Not too concerned. I'm hoping they will get enough iron from all the other stuff I give them (dr. Earth dry amendments and concentrate, foxfarm soil, wormcastings, seaweed fertilizer).

I went to your link and it said not currently available for all sizes. Maybe doesn't ship to Canada tho unless you're in Canada too then I don't know why mine says none there. You'll probably have plenty of iron in that stuff you use but it's useful in hydro or soilless media like I use.

RO water doesn't deplete anything. I just doesn't add anything. Like distilled water it is pH neutral so don't bother testing it until you've added something to it. It does work best for flushing if you feel the need as it can carry away a heavier load of salts than tap water that already has lots of mineral salts in it. Tap water to soak the pot and do the initial flush then a batch of RO water thru to really clean things out.

I have an air stone in my water jug downstairs and a 50W aquarium heater. i'll plug those in a couple hours before watering so it's charged up with O2 and around 80F as the microherd in the rootzone really like to be warm. Even tho I grow soilless I add myco and will use some of my unfiltered dugout water to introduce good bacteria. Got frogs and little fishies in the dugout so it's healthy water for the most part. I do like to add manures and EWC along with lobster/crab shell and insect frass to some of the mix for that 'organic' flavour and just to see how the plants like it.

:peace:

Great info thanks. So in theory I should be fine with adding just RO to plants when not using the seaweed or dr. Earth concentrates bc all the stuff in the soil will blend with the 0 PPM water, yea? I don't intend on ever letting runoff happen until final 2 weeks since I dont want any of the stuff in the soil flushed out until the end.
I still would like some organic product to have at home for peace of mind to quickly bring water PPM up if needed. The organic calmag I posted seems promising, I just wish there was someone that's used it before that could confirm. I'm still open for other suggestions and also still doing the eggshell vinegar thing. But that will take time.

I don't go for runoff either. I just make sure not to overfeed so I just give them enough water to soak the pot and if there's a bit in the pan it will always suck back in 15 min or so.

Salts don't build up unless people are giving them too much to start off with.

If you're feeding organic you shouldn't have to flush ever. How would you flush them if they were growing in the ground outside? All sorts of testing has shown that there is no difference in taste or ash colour whether flushed or not. that grey ash thing is more bro-science too. I just hit my bud in the pipe enough to cook off the resins and then the ash is black. If I put the flame to it again I'm just burning off the carbon and other plant stuff I don't want to make the ash grey. Edibles is best for my tired old lungs anyways so I just do one-hitters in my little pipe.

I used to make my own calcium nitrate with eggshells or marble chips and conc. nitric acid but calmag is easier and I need the acid to make silver nitrate so I can use that for STS and get me some fem seeds.

Of course I find the pic after the post. Dried eggshells in the jar.

Silver meets hot conc nitric acid reaction. Outside for this.

Wow. You are a real chemist lol. I'll definitely do the eggshell method over the next week. I got apple cider vinegar and more eggs today. That and molasses should be a good homemade calmag. Prolly wont even need the TPS calmag bottle but Im still really curious to find out if anyone used it or if there are other organic calmag options I haven't come across yet.

You're right. I went back to school for 3 years in my 30s to get a diploma in environmental chemistry and that was 30 years ago. About all I remember about it is basic stuff like how to do stuff like that. Taught me metric so I can easily use it and imperial when the subjects come up.

Jack of all trades with a diploma in one! lol

Link HERE for making what you want with vinegar but used as a foliar spray. I was ending up with calcium nitrate which is fine to use in watering and a common fertilizer. Concentrated nitric acid is hard to get as it's used to make explosives so not sold to just anyone. I worked at a hazardous waste disposal facility for a couple years as a chemist and took a lot of stuff home from work. I only have about 6oz of acid left so I'm not going going to blow up much. ;)

You can use Epsom Salts to supply the Mg and get some S along with that.

Great stuff man. When making the vinegar/ egg shell mix, is it better to grind the eggshells up than to just crush them probably, yea? And if doing so, why even strain them out? Why not just leave them in so it all goes into the soil eventually?

Crushing them is good enough. I would grind them fine if just adding shell to the soil as it would break down faster the finer it is. The shells are almost pure calcium carbonate which is not easily used by the plants until broke down by bacteria and fungi in the soil. Organic matter of all sorts has to be broke down by them before it can be used by the plants so it's important to have a healthy micro-herd or organics doesn't work so well.

It gets broke down into the same salts that come ready to eat in hydro nutes.

So I think I found a quick and ORGANIC solution after researching this for so many hours and being unable to find it on my own, someone in here recommended this one in a different thread. Its derived from kieserite and gypsum!!

I'm so happy. Just ordered it. I'll still try the egg shell method but I'm no longer in a rush to do that and dont have to eat tons of eggs the next few days lolol

I use ro water and I have no problems. Ffhf,Bas craft blend, ewc, grokashi, perlite or pumice, all I've used in veg. And build a flower in flower. It's really easy.

Yup, in theory my supersoil should have everything they need but a buddy including people in here have suggested that you should always put a little something back into RO water to get the ppm up just a little... it's my first time using RO so trying to make sure everything is right since I really wanna nail it this time, know what I mean?

I hear ya! Do what works for you and your plants. My tap water is crazy high ph and ppm from calcium. I used to dilute it 50/50 with ro water, but the Craft Blend seems to keep my plants green and happy, so I just started using plain ro.

It kind of defeats the purpose in my opinion to clean water just to add dirty water back. So you end up with water that's not completely dirty, just a little.. ima try to be a purist on this one and see how it goes lol
I ordered the roots organics calmag so I should be straight

Do your thing! You'll never know unless you try! :bigjoint:

Will get the calmag in a couple of days, but got the ground oyster shell I ordered over the weekend today. There was this thread in which this dude talked about oyster shell flour and limestone being soluble, so I'm giving it a shot. Started with 1 tbsp in a gallon of RO water for now. Will feed in the morning. Ppm is around 40.
