How does bottom feeding coco perform in leaching excess salts, compared to DTW?
I use DTW and it's incredibly simple to set up, with timers, but it is incredibly wasteful, IMO.
Failing to do a side by side I can say that since running dtw coco (for year+) I have yet to touch the yields or quality I was hitting routinely with bottom feeding (sip style)
The amount of water I don't have to make bottom feeding than I would have had to for dtw is worth the switch. Salt buildup might be an issue if you're using the same containers but a cleaning every 10ish weeks (1 per run) should suffice. I haven't seen anything to suggest to me it's a problem.
Vader OG was the first one I saw pulling nice tables of coco flowers with flood n drain, I tried it and it worked great. I get wild hairs every once in a while and switched back to dtw now regretfully.
If your dtw is dialed in, proper drainage, appropriate water amount per time, appropriate frequency etc it works great (especially waterfarm style with rocks) but I prefer bottom feeding now after trying both within close time frame.
