put some gypsum on her..
I don't have any...What do you think she needs?Calcium?Sulfur?
put some gypsum on her..
150 grams per 10 liter pot??
Me add one tea cup on 200 liter of soil and it get balanced and buffered,this your amount
looks like mighty overload.. there could be PH issues for plant if too much lime is inside
mix.
Also you "burn" your soil faster,there is a saying about Ca that "fathers" will celebrate but "sons" will suffer... and this saying is specifical for those that add too much lime,
its harder to revive this soils,they go dusty over course of a time,you need to use
more organic matter to made soil again proper bio active as this Calcium burns
more than you wish... its a death circle for soil life and organic matter..
Hey D,
im still new to gypsum and lime, like i mentioned,
but they are not the same thing!
what you are describing is about lime.. but gypsum is nearly the oposite
Gypsum does not change the PH!!

Lime, or calcium carbonate (CaCO3), is the naturally occurring mineral used to improve an acid soil. When the soil pH is less than 7, acidity exists as an accumulation of hydrogen (H), and aluminum (Al). Aluminum, which is toxic to plant growth, is soluble when the soil pH is less 5.5. When hydrogen accumulates on the outside of a soil particle, or exchange site, their presence is measured by a pH test.
When lime is applied to an acid soil, the carbonate molecule (from lime) & hydrogen combine. The end products from this reaction are H2O (water) & CO2 (carbon dioxide). Calcium is now attached to the exchange site. Because the carbonate liberates the hydrogen, the soil pH will improve (become less acidic).
Gypsum, or calcium sulfate (CaSO4), is a naturally occurring mineral. It provides calcium & sulfur, both essential nutrients, but does not affect soil pH. It is a neutral salt (pH is ~6.7) & has a salt index, or osmotic potential, of 8. It typically has 20-22% calcium, & 16-18% sulfur. The sulfur is in a plant available, or sulfate (SO4) form. In addition to providing needed nutrients, the calcium in gypsum is soluble, even at a pH that is >7. This can be very helpful in improving soil tilth, reducing soil compaction, & improving aeration.
i picked this up in the Cec Thread, i might have made a wrong calculation, but they call for 1 lb per cubic foot..
1 cubic foot = 28 Liters
1 pound = 450g
~30L /3 = 10L
450g / 3 = 150g
10L=150g
correct me if im wrong..
anyhow im giving it a try and so far they are loving it
Ups.. you are right bro,i talked about agro-lime and you use
gypsum,its a different things,i agree..
Excuse me,was think everybody here use agro-lime for buffering.
Thanx for info,good to know this facts about gypsum... very
interesting indeed.
CaCO3 is what I use... makes a lil higher the pH, great for peat.
My keeper Corey's 3 Kings, 39 days in!
BRO... WTF
Killer!
39 days... she is going to yield big time by the looks of it.
