Duel CXB3070 grow log (Pops' tomaters)

Some of you may remember me mentioning my dad was making 2 48" 3 cob diys on their own each HLG-240H-C2100B MW driver. Turns out I built em. ;P
He was busy a lot so I ended up just doing it. The potentiometers are mounted on them and they honestly look pretty damned clean if I say so myself.
But alas, they were first finished tonight and it's a good thing. The tomatoes were getting bigger and needed more light! He's growing 6 heirloom kinds:
Cherokee Purple
Pineapple
Green Striped
Chocolate
Black Krum
& Black Cherry.
I'm excited to see how it turns out. This is a recirculating DWC system I hand built for him for Christmas and it's nice to see it being put to use.
The roots haven't quite come through the net pots yet, so no waters being used yet. Just top feed for the next week or two. But he went all out getting a tray and shut and it really turned out awesome. More to come...

Sorry for the double pics. :/

cool wish my son would build a few lights for me

Few pics of how it all works

Here's a few updates. The seedlings are exploding under these cobs.

I can't wait to pop my maters. Start em indoor. Veg some monsters and move outside in early spring. Very cool dwc system too. Well built
