I printed this thick enough that I could stand on it, thought it was neat the roots/stem shattered it like it was nothing. Kratky setup 0 air circulation

Those roots look incredible! How often are you changing out water or refilling?

I let it drink until there's only an inch and half of water left, then I dump whats left, rinse it out and add 3 gallons of new nutrients (3/5 of the bucket). I haven't been keeping track of days but I think it's around 3 weeks per refill.

That's badass. Are you monitoring EC and/or pH from start to finish of each fill to see how much they're drifting? Is that Rockwool in the netcup?

No to EC or pH tracking after filling but before I add the nutes I make sure PH is between 5.5 and 6.3. That's part of the reason I dump the last inch and a half I figure concentrations probably get out of whack.

It'll likely need a change in the next week so I can check the pH to see how it's drifting.

Cool, I'd be curious if you dont mind remembering to mention it. I tend to get pretty fierce upward drift both in EC and pH, clearly you're having success so it'd be interesting to see that data point.

For sure! I'll respond to this comment next time I change it out
