PH worries can be addressed at any Hydro equip shop & My first grow I didn't even care about that as solutions were changed religiously weekly! I even dumped the old stuff on the garden so nothing went to waste! I read through this thread & Ebson salt I saw mentioned..DO NOT USE as it contaians "SALT"....Sulfuric acid can be had at any pool supply section or pool supply store! As for pure lime - major garden centers!

I use an Ebb & Flow unit so its not to hard to controll me PH now that im use to it. The easy way to do it is i have an advanced tester that is always testing and slowly adds drops of up or down *mostly down* into my tank untill it reaches and stays at 5.8 The other way is just to buy a product called PH perfect. It is a liquid solution that makes your PH exactly what it needs to be as long as it doesnt start higher than 7.5 or lower than 4.0, hard or soft water doesnt matter it will do it all. This product is very good if you are doing DWC or Soil grows. So remember hydro fans 5.8 is where you want to be =)

Can I add my own learning curve here? Right .. PH 7, lovely lovely PH7, the most neutral of PH's, most plants will do well in a compost that is ph7 or near to it... now I thought a lower ph meant lower nutes, NOTHING COULD BE FURTHER AWAY FROM THE TRUTH... we learn from our own mistakes, mine was ASSUMING that lower meant lower in everything etc wall.gifwall.gifwall.gifwall.gifwall.gif

so if the ph drops, as fertilizers get added over time, is it better to start with a soil with a slightly more alkaline ph?

Ok I am going to write this and I may catch some grief for this but here we go. I have not checked my ph on anything going into my soil in a long time. You do not need to ph organics. I use general organics with an organic soil mix. I only check my runnoff every now and then if there seems to be something wrong. As for actually adjusting my ph I do not adjust it, there is no need to. As for adding things to adjust ph, if you are running in an organic grow DO NOT USE sythetic ph up or down. The ph down isn't as bad as ph up but they are not good for the micro life you have going on in an organic garden. SO if your worried about ph GROW WITH ORGANICS and you will be just fine. I hope this helps.

you can adjust the ph of organics with things like lime to make it go up and unbrewed coffee grounds to go down (brewed coffee gronds are great for soils and composts, but are usually ph neutral.)... i also think theres some organic ph adjusters on the market

and playk328, soils do need adjusting. even organics. the ph you have may be just right. but many times its not.

even when growing outdoors the soils may no be the right ph. especially in pine forests where the ph is acidic...

Well, I decided to use promix hp because I was thinking it would be easier to work with. I'm finding the ph of runoff is very hard to correct, it's still under 6, and can't seem to get it to the 6.5 mark. I got a Technaflora ph up bottle, and am pouring huge amounts in to correct the low ph of the runoff. When the water settles I can see the chalky residue built up on the bottom, so I stir it up again. Do you just keep adding the ph up until you get the correct reading ? I haven't put nutrients in yet...just trying to wet the promix first and correct the ph. I also found some dolomite lime but haven't added it yet as I'm not sure what amount to add to 1 gal pot, to increae the ph. Your help or suggestion is greatly appreciated. Thank you

Hi guys my first post here. : ) My water PH is 7.0 My soil PH is 6.3 My runoff water after feeding Heavy Harvest Summer Blend is 7.0 Should I add some lime to bring up the soil PH to 6.8? And If so, each girl is in 4 ft round by 2 ft deep hole. How much hydrated lime would bring up the PH 5 points? Thanks for your help.

pretty quiet around here... Well I tried about a 1/2 cup of hydrated builders lime per hole. After two days my soil ph is 7. I watered it in. Then flushed to avoid root burn. Hope its not too late to get some growth from these stunted little girls.

G'day dave...sorry I missed ya first post...builders lime is not really good enough, I think [gonna hafta check it and get back to ya]...it takes some time to break down...soil ph 6.3 is not a major emergency...a good flush of ph'ed water will often settle the ph in a reasonable way, IME You mentioned ya growing in pots of soil, but did not mention a brand or mix or if you have added perlite or anything...if it's straight soil it may take some time to dry out ... muA

Thanks for the reply, I'm in the ground hole is about 2 cubic ft. with a mix of potting, and local soil of a sandy loam type, with some bark mixed in for holding water. I have not noticed any burn since i used the builders lime. I got the info to use it off the internet some where as a "quick fix". I feed twice monthly with Heavy Harvest summer blend and Granny's molasses, B1 for roots.

I wanted to use my own soil, but the pH is 7.5. I've been reading about using wood chip to decrease the pH, but i've read people having trouble with burning their plants. I'm trying to avoid things like pH Up, but if there's no alternative, i'll go with it. Just wanted to ask the question first.

It's a little high but not bad, I would just keep my water properly pHed and you should be cool.

Cheers man. That's good to know. My tap waters around neutral (6.8) so it might just be fine. Never hurts to check though.

One gallon of ph Down: $27 plus shipping. So around $40 a gallon. One teaspoon adjusts 5 gallons of 8.0 water down to 6.8 - 6.9 ph. There are 767.999 teaspoons in a gallon. One gallon of ph Down makes 3839 gallons of ph'd water. Boils down to 1.04 cents per gallon batch. A penny a batch is hard to beat, and the phosphoric acid is agricultural-grade...made for this specific purpose, unlike battery acid. And stability is not a problem...I've had the same gallon bottle for two years, and no degredation of the product, or it's effects.

Lemon juice works great
