Is it lime?

[OPT]

After browsing around reading here and there, I found a thread that had pictures of different types of organic nutrients people use. I seen a picture posted of dolomite lime, and was kinda shocked when I saw it.

It looked to be greenish in color, and not as fine as what mine is. After seeing this I browsed the internet trying to find the visual look at lime. I then found a site that talked about different types of lime people use.

One is called Garden lime, which they says is the same thing as dolomite but not as high of concentrations of magnesium.

After reading that I have found that I am indeed using garden lime, which it says on the bag.

I ordered it years ago as "dolomite lime" from a hydro store, but it specifically says "garden lime" on it. It is white in color, almost looks like chalk dust. Should i be worried? and if so..i can order some dolomite lime again.

I remember on my last grow a few years ago that I did start to have what looked to be a Mag defiency during the flowering stage using the same lime. If this happens again, should I just foilar spray with epsom salt water, or will the greensand i have in my mix supplement the mag defiency? (guess i'll wait and see)

I hope you get a better answer.

What I try to do is add materials that decompose over time. My fav ( at this time ) is crushed oyster shell I get from a feed store. I apply as a part of my top dressing mixes and add to composting mixes liberally,
The natural soil "system" will balance the pH for the most part but you are correct to think ahead and provide nutrients..

Also when I brew'd my BSF compost coffee I added oyster shell. I'd like to think that is in the liquid in some way as well.

I had the urge to suggest to you to try shrimp meal for some reason.. Don't ask me why but hey shrimp shell meal? Whatever..

 

[habeeb]

to me with lime, not accounting for amount. if you see a mag def, it's from PH being off.

but there are so many variables at play here, and cannabis like mag more then people think..



to your bag, is it the sweetleaves cover on it? that is dolomite lime very finely ground. you can also if your not sure go pick some up at lowes or home depot very very cheap ( $5 for 50# )

 

[guest2012y]

Lime comes looking like chalk,greensand is acidic,but a good source of potassium(not sure a bout the magnesium)....as habeeb said,if you see a ph issue it's unlikely to be a mag. deficiency because most of the stuff we use has a good concentration in it already. Nutrient lockout from ph issues interferes with the plants ability to take up mag. And yes,cannabis is a mag. and calcium hog! Lime well bump your ph up high,be careful!!!! Listen to Jack,his methods seem a little complicated to a average grower but it all makes perfect sense if you understand the relationships between matter and the organisims that utilize it.

AKA ag lime, $5 most farm and garden stores.

Thanks Capt.

I forget that people don't hear the voices I do..

Then I feel lonely

But I get the Picture

Love the new smiles.

What mantra I follow is the Che' or Qi of life concept with the big box.

So the whole "soil" is in a system that allows for a microcosm of natures natural systems. A living force in it's smallest parts in a space we all share; you could say..

I mix materials with a whole soil feeding in mind. I study the effects and am really into my own world with it I guess. That's why this forum is important to me. It's one place on the whole internet I feel close to @home with..

So I suggest things that Mostly relate to that point of view. Big soil. life force yadda yadda..

In a organic soil materials are processed and the energy of the food web is transferred to the flowers of the plant in time.
We think of pouring NPK on it and it will grow but there is also the life energy of the plants we grow and we see them sick in small soil too often.
Blah blah..

What do you guys think of Shrimp shell meal? I can't get it in small bags so I haven't had it but when I did the quality of the bud was real high.

I may go ahead and order the #50 sack wtf..



The Oyster shell will dissolve well in my soil box and it has calcium.

Well I finally got a chance to actually reading the back of the lime bag. On the front it says "Lawn and Garden Lime" ...i read the back and it mentioned it was Hydrated lime! I wonder if that is a reason why had had what looked to be a mag defiency my last grow a couple years ago. Isn't Hydrated lime different from dolomite?

I also think this is why a couple of my AK's are showing some problems. On 2 of them the Coteloyd leaves are starting to yellow already at 14 days, and one of my AKs first set of true leaves has rust spots on them and are curling up, but the new growth looks fine. I don't think my humidity is perfect, but i doubt this is the reason.

Is it possible my gals are having problems from this lime, the roots are growing at a good rate, but the leaves themselves arent very quick to form, besides on one of my Power Plants, which is unique as hell, biggest plant at 2 weeks I've ever seen from seed, hope to get some pictures sometimes soon. Guys have got to see it.

After browsing the site, I've heard nothing but bad things about Hydrated lime. It's "too fast acting, doesn't have much mag in it, etc" So i think I figured out my problem.

Now to the solution. I ordered some real dolomite lime this time. Sunleaves Soil sweetener.

Seeing as my Veg/flowering mix is still "cooking"... and it already has this hydrated lime in it....should I add any of the dolomite lime to it?

I also have some epsom salt that I can use to water with or foilar feed for the mag, but how early can you do this?

I understand MJ loves Magnesium, but when would i try to introduce the plants to it in the form of foilar or water fed?

I composted with lime and sulfur once.

It's hard to contrast the chemical growing from the organic growing.

Some people can't..

Top dress friend.. The Lime has a chemical aspect so we should consider that; however, dolomite is a different animal in how it works I do believe,,,

There are several threads here and a look up on the limes would do you good.

Please don't tell me you check your run off for pH..

The shrimp meal thing...Hmmmm,What would be in there that's of benefit? Calcium,some forms of bacteria that may be cool,nitrogen?..interesting Jack.

Anyone else have a suggestion what I should do with my Veg/Flowering mix? Should I add any dolomite lime to the mix that already has the hydrated lime? Or you think it'll be good?

I think you should just add some epsom salt to the mix. quick lime has lots of Ca but little Mag.

You have calcium hydroxide, quick lime...white powder stuff. a little goes a long way. It is very alkaline so be careful.

I use both types. No harm if your adding the pelletized dolomite to the soil.

I was thinking of starting a thread on this, but it seems fairly appropriate to discuss here. I had a conversation with someone the other day that has been into organic farming seriously since the mid 80s, but was passively into for a while before that because he grew up on a farm in a pretty small agrarian community.
He advocated the use of calcium carbonate as appose to dolomitic lime. He mentioned that the ratio of Mg to Ca is too high, and that over time (he was talking outdoors in a legit farm situation), it would be out of balance. There was another point he made that I can't really remember, but think I have notes around here somewhere. It was something along the lines of the water holding capacity or the CEC would diminish as a result, but can't remember specifically.
A lot of people have said Cannabis needs a lot of Mg, so maybe this does not apply and is completely irrelevant, but I found interesting regardless. I've only used dolomite and never had a problem, just wanted to see if others have heard anything to this effect.

 

[OrganicMeds]

Dolomite rock (also dolostone) is composed predominantly of the mineral dolomite. Limestone that is partially replaced by dolomite is referred to as dolomitic limestone, or in old U.S. geologic literature as magnesian limestone.


Dolomite appears to form in many different types of environment and can have varying structural, textural and chemical characteristics. Some researchers have stated "there are dolomites and dolomites", meaning that there may not be one single mechanism by which dolomite can form. Much modern dolomite differs significantly from the bulk of the dolomite found in the rock record, leading researchers to speculate that environments where dolomite formed in the geologic past differ significantly from those where it forms today.

Perhaps you can answer a question for me about lime. There is a mineral mix that I use which includes 5 ingredients (glacial rock dust, Azomite, NJ Green Sand, soft rock phosphate and limestone).

Given the amount of this mix I add to 1 cf of potting soil, I'm getting .4 cup of limestone. What does this mean as far as the dolomite factor?

Thanks for any help.

I'm not really sure Clackmas sorry. I'm sure someone will chime in sometime soon and help you out.

As far as the hydrated lime issue is going. Yes, it did serverly stunt my seedlings, but since then they have almost all made a 100 percent recovery and are thriving. I think some added Liquid karma as well as occasional cal mag added did help.
