carb pretty much covered it all
never used blumats with coco myself but i understand standard synthetic coco A+B nutrients work well with them
although some additives could be a problem depending on the additive , i'm thinking any molasses based stuff
could cause a supply line problem , definitely do some research cos i'd have no idea when it comes to what's in
coco nutes & additives
i think you can find a fare bit of info on the sustainable village website in the US
you might need some extra bits & bobs depending on your setup , you can find them at hydro experts & not bunnings
but i would tend to go to eurolux-australia website & buy from them as they seem a little cheaper
the main thing that can cause issues with blumats is air , air bubbles in the supply lines or air around the carrots
when you push them into the medium , any large bits of aeration hard against the ceramic spike stopping the media
from incasing it can make the spike dry to quickly causing the valve to open & start watering to curtail the constant
drying spike
you can control these 2 things fairly easily by using a shut off valve at the end of your supply lines , it's just a tap , once
your setup but before you dial them in you can open the tap , running water through the lines until all air is removed
then turn it off & dial the system in , of cause you can just bend the supply line over on itself & tie it down with a cable tie
in place of the shut off tap/valve
as for pushing the carrot into a medium with lots aeration bits , you just need a small amount of plain coco without
aeration , push it into the media , pull it back out leaving a carrot divot & refill the divot with the airless media
then pushing the carrot back in through that airless media should seat it well for you , please keep in mind i've
never setup blumats in coco , only used these methods in soil
good luck Ayeydized hope that helps with whatever option you choose
