Thanks for help, greatly appreciate the support! Gonna try spinosad, sounds like a good option.

Hmmm, what bugs do this? What to treat, spinosad is where I'd typically lean.

I started getting these weird spots in a few leaves. I pulled them off but the pattern seems like a predator of some kind. Any identification? Outside grow, Coco loco. pH'd water mostly to this point since I just transplanted into 7gal pots one month ago. Only 3 of 8 plants showed this that...

Did this ever come to fruition? Very interested in your results!

How's Athena compare to GH Florapro or Mastercrop for composition and cost? Also Peter's?

How's it going? Seems weird ppm would drop that fast. Could be deficiency if ppm is dropping as that would indicate nutrients are being removed.

Thx! I went with 15gal buckets from HomeDepot, red lids. Black HomeDepot buckets. Found local grow shop with 50ft of 1" black tubing for $75 so bought it, if not I'd check pond company or ebay. I also bought a couple of the Jebao sine pumps, I think a 10000 and 5000. Was hoping this thread...

No takers? I found 5gal round black buckets at home depot for about $4/ea.

Is ppm swinging as well? If ppm drops over time, increase initial rez ppm. If ppm rises over time, decrease initial rez ppm. Goal is ppm stays near constant as rez level depletes, this would indicate plants are using water and nutes at same rate. This concentration will typically increase...

Agree, could be humidity. Humidity meters can be off too. Could be possibly lower. I'm newb so just guessing. Seems like one of your meters might be off. Try spraying with RO water and see if it helps.

Hoping y'all can help me out. I'm building 2 - 8 container RDWC systems, one veg and one bloom. One I'm planning 5-7 gal buckets w/ 8" bucket lid net pots and 15gal tote res for veg. Total volume ~40gal and pump will be about 400gph. The bloom will be an 8 site 15gal tote setup with 27gal...

Where's the best place to buy 5-10 gal black square buckets? How bout round 5-7gal buckets?

Where can the best prices be found for RDWC components? Black vinyl tubing or flexible pvc, 1" and 3/4"? Blue vinyl tubing? Air line tubing? Bulkhead fittings, 3/4", 1", 2" and 3" Airwalker16 provided the following in a separate thread, but they don't carry 3" bulkhead fittings...

Where'd u get black buckets for veg setup? Looking to setup something similar.

Nobody has any experience with the supercloset rdwc systems?

I'm looking to go hydro. Was going to build a diy waterfall system using 17gal totes for bloom and 5gal pots for veg, e.g. 2 separate systems in 2 separate tents, 6-8 spots per tent. I was offered a nib super Closet 24 site bubble flow system in 6.6gal pots for a good deal which is basically 2...

Ok, based on migro YouTube test, solacure T12 only output 1w of UVb at 9 inches above canopy whereas Agromax PureUV and Phillips TL were nearly 3 times as high with less input. It seems the Solacure have better UV A:B ratios, e.g. 4:1 vs closer to 1:1 for PureUV. I think that was w/ 28w input...

Great read, thanks for all the information. Do you know where the fusarium (sp?) was coming from? Guessing it came from water and maybe made it through RO filter and continued breeding in pressure tank? Did you find any way to kill/control it like UV or ozone?

I'm looking to build an 8 site with external res. Won't have a chiller soon. Thinking of using 17gal totes for plants and a 27gal external res to keep temps down. Guessing res temp will be 72-75ish as I'll have mylar on totes and insulation with mylar on lines to keep tent/light heat out...

Yes, I get the waterfall in every bucket, but the air the waterfall is mixing is stagnant in the bucket, right? I mean there's no fresh air going into the bucket so eventually the O2 will be depleted....at least to some level where it equilibrates with diffusion of air on the other side of the...
