Same strains and an extra 50-100% time between waterings.. That much a difference hey… WowWell of course I added compost. 1/3 of my base is EWC. If you look in to it the CEC of coco coir it is not as high as peat moss. Believe me, we beat this topic to death on here.
I dont think my mind was playing tricks on me as far as water retention goes. These are strains that I've been growing for quite a while, and a plant that I would typically water every second day in a peat moss base would go 3 to 4 days without need ing water in the coir.
Either way, yield suffered. Not blaming the coir per se, just an observation I made.
Nothing else added or changed? No perlite bottom of the pots, not any less fans, or lighting? Hmm. And a recycled batch so same castings?
If so, I might be tempted to consider running your coir runs with 15% EWC instead of 33% and give that a try!
Petro's research findings has me testing the theory that its better to have less (better qual) EWC .. I'm sure your castings are potent and alive, maybe give it a shot! Can always add the other 18% if you don't like it.. Despite this last study that surfaced, THIS study found that 15% was the sweet spot, and made for higher yields and more branches, with less nodal spacing.
(Petro will have it, Stow and its also on our thread around page 35 i think)
Keep us posted!!
