    Hello,

    My question is about making my own bloombooster via a recepy from RQS.

    The main ingredient is Monopotassium-Phosphate and it provides the actual PK booster.

    I have found a company where i can buy this in 25kg bags so no problem there.

    The other 2 ingredients are

    calcium bicarbonate

    And

    Magnesium sulfate

    So just cal-mag basicly.

    The Magnesium sulfate is also easy to obtain but the calcium bicarbonate is a problem. From what i understand it doesnt exist in a dry form and i cant find anywhere to order from.

    So i ask, what can i use (in dry powder form) to add calcium into the mix?

    I have been suggested to simply add chalk or cast/gypsum but im not sure if thats uptakable by the plants?

    Any ideas?

    Not sure if we have any formulation chemists on this forum to answer this for you.

    Calcium sulfate is what’s typically used. You are very unlikely to run into sulfur tox unless your levels are crazy high. If you are talking about a concentrated solution you’d need calcium chloride. As a dry mix I’d roll with calcium sulfate. Just my 2 cents.

    Hey Chris, thanks for responding, big fan of your work! Hope the gardentalks pick up again soon, we can always use more Dr. Bruce Bugbee 🙂

    Hello CamZ, thank you for the info. I think calcium sulfate wil work perfectly for my recepy. And its pretty easy to come by as wel.

    Thanks a lot!
