Both prilled and powdered dolomite lime can be used in TLO
You can also get horticultural lime that is pure calcium, or dolomite lime that is calcium and magnesi-
um. Hydrated lime should be completely avoided; due to its extreme power it can easily kill life and take
pH into deadly ranges for your plants. Dolomite lime gives the plants magnesium and calcium as well as
buffering pH from dropping too low. You should have plenty of magnesium available to your plants, es-
pecially during flowering, but too much magnesium can really turn out harsh in your smoke. It can also
lock up your soil mix into a cement-like state, starving everything in it for airflow and turning the soil
mix structure to shit, so make sure you stay on top of that. Cannabis likes a lot of magnesium, but like
everything else you can go too far, especially using things like Sul-Po-Mag (also known as KMag), which
is very powerful.
There is another type of granular dolomite lime, and these granules look like little rock salt pieces. This
type is fine to use, but be careful as it is really fast acting and highly soluble in this form. I recommend
that you use two types of dolomite lime in TLO container growing, both powdered and prilled. Make sure
the prilled dolomite lime says “Fast Acting” on it, so as not to get it confused with granular (hard rock)
dolomite lime.
Greensand, Azomite, and Zeolite
In my opinion, greensand is a must have for TLO container growing. Azomite also goes by the old-school
name of “rock dust.” Zeolite is a little harder to lay your hands on, and is an optional addition to TLO soil
mixes. I add all three of these myself, but you should try to use the Azomite in powdered form along with
greensand. Of course, feel free to use the granular form of Azomite as well, but I find that the powder is
really the best option. I use reverse-osmosis water as my water source, so I don't have a constant influx of
minerals like calcium and magnesium, etc. from city tap, well or spring water. It is important to use a pure

don't have to gamble with seasonally changing ratios of dissolved minerals and other elements, like you
do using those types of water sources. We will discuss these things in greater detail farther along, so don't
worry too much about them right now.
