Cal mag +

[postmandave]

Ive just fitted a ro sytem can anyone tell me if i have to use cal mag in the ro water in soil grows or will there be enough in the nutes and soil(canna nutes) i know its a must in coco and hydro .dont want to put it in and od plants with mag and cal.thanks.the postman

Here's how I would approach that:
RO water, yeah, you are going to have to replace the Ca and Mg even in soil.
Some ferts DO have calcium in them. For example, Neptunes HArvest Fish Emulsion has a Ca value of 1%. Bone meal is also a good source of slow=release calcium if you are doing an organic soil mix.
But I'd stick with calmag for simplicity's sake.
Have you thought about coco? mmmmmm coco

I was just reading a comment of urs that you keep ur mothers in coco and ive always been curious about coco whats it like for watering in a scedule point of veiw and how do u rate it.the postman.

It's nice to be able to flush them really well. In 1-gallon pots, 20" plants under 400w of MH at ~80 degrees F watering is every 3-4 days, watering to the point of runoff.

I was wondering how to use cal mag? Do you just get it off the shelf at the drug store? (ex..walgreens, cvs?). How much would you add to a gallon of water? Folier feed or just pour on soil?

Sorry if i am hi-jacking the thread, it is just that you have the perfect title.

thanx!:jointsmile:

Well then where were you when I was asking about it? Do you use it your whole grow or? And what exactly does hemi cellulose breakdown mean?
