I got my answers. To me it's disgusting changing the profile pics to rats. It's giving me a visceral reaction. Whoever is running this place, I hope you're proud of your conduct. Why not remove the posts of people you designate as rats? Surely their contributions are worthless? bye The Tocs...

I hope I'm not stirring shit up. I'm just curious what's going on. Did a bunch of people move to a different forum? Aqua Man's profile can't be searched either, which is a shame. Maybe somebody can shed some light on what's happening? Cheers

Isn't 2.5 EC quite a lot? I've made the mistake of trying to figure out what my deficiency was when really it was toxicity...

Regarding pppfd measurements: The Photone app (ipohone) is very accurate. Shane on Migro has done a review. I have the app and bought the LED module. It's really helpful.

Is there a reason to run both lights at this early stage? I would assume one of them dimmed is plenty and there is no reason to waste electricity. As long as it's only one or two leaves that look off I wouldn't worry about it.

I have no idea to what extent DO will vary between spots in a single system. It probably depends on circulation, consumption etc. That would be one of the many things to test. Once you’ve run the experiments that you’re interested in I’d probably settle on a single spot if it were me.

Welcome! As you might be able to see from this thread there seems to be experience from growing but not mich data from testing. It sounds like you’re in the position to actually run tests and gather data. What’s your do level now? Flooming is something you might be able to test without mich...

Change the atmosphere I will not 😁 I guess I can phrase it more accurately: What factors determine what the optimal solution is if you are trying not to waste resources? I assume a recirculating pump is always required. Venturi and airstones are extra equipment. Hence: What is the simplest...

I've read a bunch of opinions on DO over the last few days and I have not found a conclusive best practice based on anything other than bro science. Has anybody done an analysis that has the right tools? 1. Airstones Are they the best method? Is there an advantage over flooming or waterfall? 2...

Looks like a really neat setup! How are you going to control the water temps? I'm getting into RDWC after struggling with water temps in single buckets. If you keep the room at the temps that the water needs to be it slowls growth afaik... What are your plans for the CO2? Tanks or burner? I've...

Thanks for the replies. I had gradually built up to 1.5ec before the change to 1.7. I haven't found any information at all on what the ridges in the leaves mean. Not sure how else to google it :D From what I've learned it might be a phenotype thing. I've been experimenting with airstones and...

Hi everybody. I've been mostly lurking but now I'm worried about my lady, hence this post. The plant has not been growing as quickly as expected. I've done a res change and upped the EC to 1.7 using Canna Aqua fertiliser. The leaves now look good in colour but have deep ridges. Otherwise it...
