From what I have read, it does. I still add a wee bit of Cal-Mag, maybe 60ppm to my res. But on my seedlings, from now on, just distilled until they get a couple of solid nodes, then ph'd tap water ( I let it set for 4 days before I use it).Very healthy looking, and have really taken off. A lot of growth in the past few days.
You mentioned just ph'ed tap. I always have to add cal-mag to my coco. Do the Canna base nutes cover the coco's need for cal???
I agree. I have three blue spectrum bulbs and one red in my T5. The root production is always good.Adding more red spectrum during veg will increase root production. I add ~ 25%
You hear this, you hear that... ya just have to go with your gut.What's the point of the chiller and the air stones in the res? I thought the whole point of DTW was that you DIDN'T need a chiller, or have to worry about constantly checking pH, etc... I'm on my second bloom atm, in ChowMix DTW Drip, and have seen no problems due to root pathogens with res temps in the mid-upper 70's and room temps in the upper 80's low 90's. In fact even when my plants were at their worst I pulled a couple out of the pots and the roots were as healthy and as white as can be!
Definitely looks like a nice setup, and well thought out, I just am wondering about the benefit of the chiller/air pumps. I've also read pumping air into the res can fuck with the pH over time, even with just salts and RO water.
Keep up the good work, and remember that what goes around comes around. I'm sure your grower friend will return the favor handsomely for that beautiful Critical you gave him!

Personally, I use air stones in my large res, but I feed on a timer. I am concerned that without aeration or circulation to create a turbulence; think water flowing down a river cascading over rocks which creates CHI) nutes would stagnate, or just go flat (like beer)
My new aeration system provides both. See pic
