Thanks man. I just love keeping all the electrical stuff far from the plants (except the lights) keeps all cords and zappy stuff away from the grower as much as possible. I feel like the flip idea is underutilized. A lot of growers can be limited by the Amps they can bring in. And if you make your own lights it would be so easy to run one ballast on two lights.
Im a bit iffy regarding the one balast, two lights thing. It means putting relays and switching on the dc side and usually the dc spec of the relay will not accommodate too much voltage. Also it could be argued that using the ballast for 24 hours a day instead of 12 is going to half its life ; youll still (on average) going to be going thru the same amount of drivers over long term.

Ya I get you about the single ballast vs double ballast. But I've seen the price of those high voltage contractors come way down and availability go up in the last couple of years since a lot of those are now used in electric vehicles. You don't get any more life out of the ballast but the upfront cost for your setup is significantly reduced plus I always liked the idea of all the ballasts mounted in one place (preferably out of the grow room) I may actually go this way on my next build. Will see what lights i end up with and go from there.

I didn’t see what you finally used for sealing that empty between the rooms that all the cables ran through but I’m sure it was something good. If you’re looking for something that would be perfect for that check out roxtec. They make a modular rubber block system that would bolt into the hole then all the cables get ran through a rubber sealing port and when you tighten is all down it sealed it up air tight. They make several different types for different entry ports. I work in wireless and we use them a lot for running cabling into cabinets and buildings.

Btw both the build out and the animations look spectacular. Exactly what i would like, a full buildup from the ground. Our grow is much more adhoc, a hodgepodge of temporary solutions thought up in a "here and now" frame. The changes in climate and the amp limitation has always meant we need to change the grow quite a lot between summer and winter. Its a bit of a mess but getting better, we are looking at automation of gear to be able to increase our available amps and now intruducing uva, far red and uvb: looks very promising for our purpose and you could see plant health increase markedly just after a few days of uvb.

i use 2" ABS pipe mounted to the studs to give the cables something solid to pass the wall through. I left it up to the grower to plug it however he did. The Roxtec looks dope thanks for the link I'll definitely consider something like this next time

Yeah if you want to try one let me know and I could send you one to try. I have a bunch of them laying around taking up space.

Thanks Rocket! Means a lot coming from you. A lot of grow setups are done for the here and now, including many situations in my own room. I love planning out a grow for success though so I try to keep things grower friendly, like power kept as far as possible from any water, keeping equipment to the side of the canopy
In case it needs service/repair during a grow etc.

Very interesting on the UVB note as I've seen a lot of people kind of change their thinking on the benefits of UV especially UVB. But I always found CMH to give me the lushest plants with leaves that feel a little thicker than all white LEDs.
What sort of automation are you looking at to allow for more amps? Don't know if it's viable in your area but maybe some solar panels could give some added Juice but Imagine you would need a battery setup as well to run through the night. Might not be totally feasible from a ROI perspective.

Solar isnt viable due to the property not being a good fit.
The automation were looking for; few things but mainly to get our quest dehueys on a separate thermostat (or whatever youd call it for humidity): it would trigger dehuey while dimming the lights. When it goes off then dim lights back up.

Were using uva (2:1 400nm to 365nm ratio) and uvb 295nm and far red. The results in plant health are visible to your own eyes. Next we will see about yield and potency hopefully for more quantifiable results.
It was a bitch to have to solder all: there were a fair few hiccups and shorts and just general stuff i didnt expect. Next we will be doing strips with the main uva/far red and just have the uvb as monos. But i may take some time, finance is stil tough. But eventually its something we want over each tray; from seedlings to flower. The reasoning is maximizing; both space and our amp limit.

Thanks man that's very generous. Are you in the US or Canada? I saw Roxtec has a Canadian part on their site so I think I can source them here.
I’m in US couple hrs from the Canadian boarder. Not sure if it would be a pain to ship or not but if you ever what one just let me know and we can work it out. I have several different styles.

That's a clever idea about dimming the lights to run the dehumidifier. However potentially it may not supply the dehumidification you are looking for because if you are running AC to cool the room then you will lose the dehumidification power of the AC while the lights are dimmed. so the quest will work much harder to achieve dehumidification in that period without the AC helping out. You could combat this with a propane/natural gas/ethanol heater in the grow room (equal in BTU to your lights). So if you are running like 5000W in lights then you have 17,000 BTU/h to make up for when you dim the lights. So heater like the one in the link below would keep your AC going while the quest does it's thing.

an even better product would be able to turn in and off in automated fashion to be on with your Dehu similar to the propane CO2 generators which can take a 120v input for signal to start and stop.

We actually have to add heat for the winter season. Looking to cut out the AC heating by dropping in some kind of incandescent as a heatsource directly for the cannopy. Bonus they will have plenty of far red and hard to access 680nm red, chloropeak ;)
The main thing is how to do all this without switching the quest on and off, only triggering the unit.
