Question Dolomite Lime?


Topic starter

Hi Percy's. My question of the week LOL

Back before my days @ Percy's, someone somewhere told me to get some Dolomite Lime. I can't for the life of me remember who, where, when, or even why, but I have 5 pounds of Down to Earth Prilled Dolomite Lime that I have absolutely no idea what to do with (If anything) When to do it, or how. So figured this would be the place to ask for advice 😉

Any words of Wisdom?

I use dolomite for calmag supplementation in my outdoor grows, I have heard of people using it to make their own calmag solution but personally I have never used it as a liquid feed only as an amendment for soil. From memory it isn't as water soluble as one might think and takes a little longer to break down and become available to the plant as opposed to liquid calmag nutrients. But you don't need as much to get the desired result either, Its just become a staple in my dry amendments line up for soil grows. 

I feel like a, like a slice of butter... melting on top of a big-ol' pile of flapjacks... yeah.

Thanks @bubblehok 
So as I'm using CalMag in my feeding schedule in the little hydro-toy grow, and as of yet have not needed to add anything to the grow in the larger tent other than I'm about to top-dress the 6 of them (they are the 50/50 FFOF and Happy Frog) so I probably wouldn't need it for much of anything then, I wouldn't think?

@mr_kryton No dramas mate, I wouldn't bother using it unless you are in a pinch and run out of the calmag you have, or if you decide to do an outdoor run and want to amend the soil a bit. But just because I only use it for soil doesn't mean you cant use it in place of calmag. Experimentation is the name of the game with this hobby and I think finding what works best for you and the way you grow is key to good harvests and quality smoke.  I'm sure some of the other lads have used it too and have other insights into it, I can only give you my experience with it.

@bubblehok That my friend, is why I ask! If my seed order ever clears customs, we have actually ordered an Outdoor seed mix. But just like the original order and replacement shipments, it has arrived at ISC Facility in Chicago and again fell off the planet 🙁
Guess it's time to look for a supplier in the US and at the very least avoid Customs... 

@mr_kryton Yeah I feel your pain with customs bro, and my bank wants to charge me $50 just to facilitate an overseas transfer... the order was only $100.... and if they don't get through customs its lost money. Thankfully some came through and I will have some Blue dream and Charlottes sister in the next few days. Have been waiting on blue dream for ages. Still waiting on the Mimosa cake to drop and have a few others I want to try but need to be able to get them in the country first lol.

It's all B/S! 
The Mimosa Fems were the reason we placed the order in the 1st place. Added some mixed Sativa and the Outdoor mix to finish off the order. So far, have a nice hole in the seeds fund and that's about it 😐  50 buck for an over seas transfer? Holy Crap!

@mr_kryton Yeah at least you have some decent genetics being stocked by providers in your country, its almost impossible here, and yeah the fee was absurd and I don't think the bank wanted to do it to be fair, but I also don't know what the fee on the other end may be so by the time I had paid and sent the money I would have more than likely still owed for the purchase and ended up paying double, banks like to slog you for anything they can here unfortunately.

@bubblehok true, I've been looking for sure, the biggest issue is going to be convincing the "Boss" that the ~200 bucks we spent on that batch is just a loss, and can I have another couple hundred to get some from in-country LOL
She still thinks that they'll all show up sooner or later, but from the horror stories I've read about from that Facility, I'm doubtful. If she does happen to be correct, and they do show up some day, we'll have quite the collection on-hand 😉

@mr_kryton Its always the hardest part mate, the CFO in my household would spit chips if I asked for more because customs stole it lol


Lime is commonly used in agriculture as an amendment to manage pH in soil and has been since ancient civilizations found the best way to get good crops. It's not really mystical hocus pocus or some secret weed growing fucking bro science. Just regular science.


@teleman yeah i have seen it used for that as well, almost like a buffer and I suppose me adding it into my soil it does help with the ph as I never really have many issues ph wise in soil, have seen plenty of people using it as a calmag supplement though also, that's the thing with cannabis growing, everyone has their different techniques and it is always awesome to see different approaches.


I must admit I was completely arseholed on bison grass vodka when I posted that answer. Apologies if it came across a bit feisty! 🤐 😋 

@teleman it's all good Bro 🙂

@teleman lol all good mate, was a passionate agricultural explanation 🤣

@teleman I like a nice and feisty answer every now and then bro 😉
