This run I started using coco. At peak drink (days 20 - 50 of 12/12) I was having to water so much and so often that my RO filter was barely able to keep up and the filtered water did not have time to warm up to room temp. I started using aquarium heaters to get the water temps up to around 80F. This helped growth rates dramatically. Cold roots = very slow growth and during flower that means loss of yield.

If I was running DWC then I wouldn't want my water warmer than 70F because the dissolved oxygen is the only oxygen the roots will get and above 70F the waters ability to hold oxygen drops radically.

You can over water coco. It should be allowed to dry a little between waterings, but not as much as soil. This allows the roots to get some oxygen and prevents root rot.

That goes against everything I’ve ever learned. Isn’t 68/70 degrees best for watering ??

Hello, just a quick question. So this is my first time growing in Coco coir, that being said I've done the research and it's advised to rinse the coir good! Then buffer it by adding Calmag. Okay, I understand all of that. My question is after I've done that and everything is good to go my plant is in its new medium. When or do I start adding Calmag into feed schedule? I've tried asking around Google but nothing is giving me the answer I'm seeking. Hopefully all of that made sense

Firstly what brand of coco did you buy?

What nutrients are you using?


Most coco specific nutrients have more Ca and Mg in them to help with the way coco holds on to Ca and delivers back K.

Answer above and then I’ll help you.

Never heard of any of those.


But a quality coco fibre will already be buffered.

And coco nutes will contain elevated levels of Ca and Mg.
