very nice set up
FYI, if this is a RDWC then air stones not needed

foil will retain heatMade a few changes. Unrelated to them, I almost lost both plants
One of the problems with DWC is water/nute temps, which when too warm it will cause problems due to low DO. So, I did 2 things using things I had on hand (see photos)
* I wrapped the tote in aluminum insulation
* AND, since I am using a F & D tote, which already has a bulkhead, I inserted an o/o valve and put a bottom feed pump in a cooler and drain the nutes into the cooler to which I add a couple blue ice packs, and leave them in the cooler until the temp drops to ~ 65*s, at which point I turn the pump on to re-fill the tote. Once the nutes back into the tote, I close the valve and repeat every ~ 3 hours during lights on
Avoided a Disaster
I can't stress enough the importance of a strong multi-head air pump that has a adjustment valve. This allows for compensating when the water level is either too low, or too high. A week ago it was too high, and I was afraid of soaking the starter cubes, which would lead to root rot. Setting it too low and not enough droplets were splashing into the net pot= no root development. That almost cost me the small plant, which barely had any roots outside the net pot and completely dried out!, whereas the larger plant has roots down into the nutes. When the adjustment was too high it was likely getting too wet and started to get RR. Late yesterday I noticed some browning and wilted leaves. Last night I took it out and soaked it in ~ 5% H2O2 for ~ 15 minutes. This morning she's perked right back up, as has the small one
hth
Just watched the video waiting on the numbers . Got the AMARE BAR 6 installed. LOVE the UV. Reminds me of the old 70's days. Have it on the lowest settings. Can't wait to crank her up!
Why is the light Blurple?
Ha!! I have done that and don't forget your calibration .... That stuff gets old and will throw your cal off.Im a dumb ass. Didn't even think it could have been the batteries, and it was, but it doesn't hurt to have a backup
After a week of no growthI made a fresh batch of nutes. Not being at all sure why, I had been blowing the fan (quite gently) over the 2 plants, so this morning I put it on circulate. Fingers crossed that one of these works
that and the amzn overnight expectation.... lmfaoIm a dumb ass. Didn't even think it could have been the batteries, and it was, but it doesn't hurt to have a backup
sigh.... the blue of their teeth and platinum blondesIt' looks purple because it is only the UV diodes on. Remember the "blacklights" of old they made everything look like that.

Need to use those old nutes on the lawn....Editing time ran out on the above post, and I can't even delete it WTF?
The one thing that has worried me is I ran out of both NPK Raw Grow mix and Emerald Harvest Grow 3 part nutes. So, this grow I have been using 4+ years old Hydroponic Research V + B but the dry powder has changed colors to a light orange, and is sticky. I just checked my backup pound of V + B, which is noticeably lighter in color but still a bit sticky, making fresh nutes with it now, but I just ordered NPK RAW Grow nutes. Be here Wednesday thanks to Prime
The previous nute change I added too much Kelp (< 1/8 tsp/2G, attempting to stimulate root development), which made the nute solution look quite dark and precipitated out of solution. Since changing that out, cleaning the DWC tote and making fresh nutes, no discernible improvement, AND, pH STILL keeps rising 1 full point + daily (set at ~ 5.3 but jumps to 6.5+ by days end)
Dunking both in H2O2 several times per day
I may well need to drop some more seeds
