HELP- first hydro build and grow

But a stable pH in a hydro setup may not be as desirable as a fluctuating pH given uptake of nutes atvarying pH levels. A range of 5.8 to 6.5 works quite well for these plants.
 
I don't understand what this means

Neither do I. pH ppm and temp is all I ever checked. Probably why I had so much trouble with DWC hahaha
 
5.7-6 gets all da yum yums. At least according to GWE’s hydro ph nutrient chart. I currently grow in coco. I set to 5.7 in a 5 gallon res and never check again until I refill. Not saying that’s recommended, but it’s working alright for me. I agree with you in practice the fluctuations in ph is beneficial, but of course only within range.
 
I just did some reading on those nutes and it seems interesting. However calcium based nutes would not read on an EC meter like salt based because calcium is conductive in elemental form, not dissolved in water.
 
Just checked the pH and it's holding at 5.9, been there for the last two days,is that normal??
 
pH is6.0 this morning, I wonder if I should change the water in the bucket,I want the pH to fluctuate right??
 
I'd say it's a good thing if it staying stable. They love a stable environment. The pH levels in your outdoor garden dont fluctuate and you can grow some decent hooter plants there.
 
It's a photo yea.. no reason why you can't. I had varying results from 4-9 ounces per plant in dwc...
 
It's been 8 days since I put the rock wool in the basket and I still don't see any roots,she seems healthy and happy,I have to admit, I'm a little confused
 
Does sound a little strange, might need more time, maybe the Rockwool staying wet enough that roots don't want to grow, or is it too dense for the roots to permeate... 🤔
 
Hmmm, that was an interesting read,the mixture is touching the bottom of the basket, maybe I should change the water and keep it just below the bottom of the basket
 
Yea you might be onto it, don't want the mixture touching the bottom, I'd say 2-3 inches gap to start with.
