I don't add anything to my res all inputs are done via top dress
Also I have never really felt that checking run off was an accurate way of determining soil ph
I think a proper soil ph meter would be the only way to truly know and they are a little more expensive then I am willing to pay at this point
It is a bit perplexing to me tho..I have seen examples of other growers running their SIPS covered with no issues so I am still searching for the answer some where and I am glad that
@MrOldBoy inspired so many of us to use SIPS as it gives us an opportunity to learn and help each other dial in these containers for cannabis use
It is also interesting how earth box recommends the use of dolomite lime for each planting there must be a part of the answer there. although I have always added dolomite I used a type that was not as finely powdered as the bag that comes with the earth box, it was a coarser blend, I also may have used less than the amount earth box recommends maybe the lime I used did not break down quick enough to offset the acidity and/or I did not add enough
I do remember the first thread I saw from
@MrOldBoy and his beauty Sams crack plant ...if my stoner memory serves me right he used the mulch cover and did not add dolomite at all...and we alll know what a beast that plant was
One more quick thought...I don't really want to use dolomite anymore..I would like to use oyster shell flour instead if I can. The reason being is dolomite lime is also high in magnesium and too much magnesium in the soil is hard to get rid off and I believe can also lock out calcium?
Thanks so much for the discussion fellow growers and
@WildBill I
hope we are not derailing your excellent thread too much!
