Since you’re already kind of stuck though I would do it by hand for the next couple days and go build an rdwc system on the side and transfer all those plants into it seeing how all you have to do is hold the lid up. Not like it’s gonna shock them either it’s literally the same system done smarter.

Same and it was 1 bucket lol... more work than my 4 site... but I sure learned about stability 😁

Man I'm dealing with algae in this rdwc. Constantly massaging the roots. Now my dwc, while tedious, has treated me far better in regards to algae.. It only lasted a week. This rdwc seems like I should do res changes every 3 days.. While my dwc just requires topped off.. And lasts about 10 days before I need to change.

Im sure it's light leak, but I can't really fix it better until this grow is done. I can't complain either way honestly.. All 3 plants are doing might fine given the contraptions they sit in.

It’s most likely from the white buckets. Try just wrapping em in a reflective paper. Like Mylar. Or aluminum foil. Lol

I have general hydroponics drip feed hydro farm and I had algae in it from the fluid level tube being translucent so I made a slip-on cover with cardboard and duct tape lol it works

Dark blue buckets wrapped in black rubber. My white pvc lines are wrapped in duck tape. Lids are covered in black then white tape. I think the white pvc with one layer of duck tape is my issue. I do use white lines for air and black tube for flow.. Idk I find I'm gonna be using alot of hydroguard. My temps stay around 72.. Growth is amazing though on the rdwc. Just annoying lol.. Not only do I have to do all the Checks.. But I gotta massage the roots every 24 hours lol.. I'll fix it when this grow is done and I can tear it all apart. Thanks for the pointers guys.

Yea I was honestly planning on switching to rdwc soon as I can afford to. This is also my first grow so I didn't want to go that crazy with no experience. I upped my ppm's to around 850 and now they're drinking 3 gal in about a week.

I would do it sooner then later if you plan to continue doing this lol

You’re honestly talking about a $30 water pump, 8 bulk heads if you do it right I’m assuming it’s a 4 site @ like $2, a box of 3/4” tubing @ $25-$50, a 6 way manifold for the drip lines which is like $5 at hd, 1/4 tubing for the drip lines, 5 air stones you should already have and the rest is all shit you should have already. That’s less then $100.

Just take the plunge trust me.

Post pics of this algae on the roots you speak of

If it really is algae which I doubt it’s inside the bucket on the roots highly but assuming I’m wrong they sell black painters plastic at hd by the roll for dirt cheap just wrap your buckets in that.

You guys also realize you can take a dehumidifier and use is as a chiller as well right? There’s some wiring involved but if you’re game and aren’t scared it’s a lot better then spending $600 on a chiller that may or may not last.

You just have to bypass the controls and wire in an external thermostat controller but you can drop the evaporator coil right in the water. A 70pt dehumidifier has almost a 1hp compressor that’s a lot of cooling.

Just saying most problems in dwc come from hot water and the ph being off if you have both of those right it’s almost impossible to fail.

Dang just cleaned it up. Its prolly not algae lol .. idk what it is. .its a slime that builds up on some of my water pump lines, its brown and under the water. It starts infecting the roots causing root rot. When the roots get the slime, they turn brown and get little brown spots here and there. Perhaps im conflating root rot and algae growth. Its not growing on top of my rockwool, its not green. I thought root rot only effected roots. The more I think of it the worse it is where light could possibly leak. Then the roots that get caught in the filter turn into brown slimy mush if I dont clean it every 12hrs. . . which some days its impossible working 12hr shifts :(. I cant even massage them but once a day due to work and 12/12 cycle. Dont wanna risk light leaks.

It stays around 72, which ive heard is fine. If I want to cool it I can inline a copper coil in the ground outside 5 foot away for under 100. Not to worried about the temps but I do get it. Im just assuming if I fix my light leaks ill be fine. It doesnt happen to my auto anymore, worked it self out of it somehow. . these seem to be doing the same. .just sucks.

72f is a great temp imo. I won't get started on it though lol
