My apologies. My phones been acting funky and I wasn’t sure if the first one posted, so I posted again just in case. It wasn’t intentional, I wasn’t trying to spam. Sorry

So I’m running a 30 gallon rdwc system and I was wondering if my tap water would be okay to use? It has a ppm of 197 and EC of 395 which I’ve heard isn’t so terrible. The only problem is I know for a fact my hard city water contains small amounts of fluoride and of course chlorine/chloramine...

oh and I’m using 2” slip bulkheads I got from marine depot. Drilled my holes a bit low but 4 bottles of silicone RTV 4500 and some oateys pvc glue did the trick hahahah. I guess if it works, it works, right? I also went overboard on the bulkheads. Wanted to make sure to have some failsafes in...

I actually switched to tankbarn 5.3 gallon buckets. Liked the shape a bit better. Here’s the finished product :)

thank you so much!!!! That’s a great idea!!

What ppm should my rdwc be when I transfer my Rockwool (sprout from seed) into the system??

Hey, @myke i forgot to ask. What kinda of air stones do you use with the EcoAir4 253GPH air pump? Size? Cylindrical? Spherical? Disk? Brand?

yea I got both of those.

I have a drain in my shower but it’s like 15-20 feet away.

I have two, one Danner mag drive inline, and a Hydrofarm active aqua 800gph which is also inline One is just a back up for redundancy. The pump pulls from the res and splits off into each of the 4 buckets for a waterfall in each one. The return to the reservoir is gravity fed.

mind showing me a picture of the valve and T drainage system you’re talking about?

so root rot is a definite possibility. So I may need a way to fully empty the system If that problem occurs.

Getting a chiller around Christmas time when I can afford it. In the meantime, it’s winter and the ambient temps in my grow room stay at between 60-70 where the res will be. The tent is about 75 ish with the lights on. I’ll be using HydroGuard in hopes that it will help my plants tolerate a...

I actually haven’t even built the system yet. Just want to get it all planned out so I don’t run into problems I’m unprepared for. And yeah I know I need to change water every 1-2 weeks. Yeah I thought about using my spare pump to do changes and refills. But I won’t be able to get all of the...

no floor drain I think I have a shopvac tho

I’m about to start my first RDWC waterfall grow. Hydro noob here, so I figure I’m bound to run into some problems which will require some complete res changes (system holds about 30 gallons). So my questions are: How the hell do I drain my system in case of root rot? Also, i use a separate tote...

you ever start seeds in Rockwool by any chance?

where it says week 1 (300-500) is that the strength of the solution? or is that the ppm u dilute the solution down to for feeding?

4 site (5gal each) with 27 gallon reservoir. Using RO water btw. Nutes: GH Flora trio, CalMag, Floralicious plus, HydroGuard, and RapidStart. Im starting from seed in rockwool, i was wondering if anybody who uses these nutes has a feed schedule thats worked for them? I'm planning on running 4...
