What must be remembered when evaluating costs of these led systems, is that heatsink material, no matter if it's u channel or proper extrusions, cost money. I think there are savings to be had by using more dense F series strips. There is also a lot of labor saved by going with fewer strips, or with...

Nice upgrade, JGG !

Yes - that’s cool. I hadn’t thought of using them that way. I have a couple of the low voltage Sonoffs that have Inching too.

For sure your growing some stinky strains. Perhaps you should google low odor strains or something.

It does sound like you’re growing skunk or something. Those smells really make themselves known. I’d try some other strains. I haven’t had any really smelly ones yet.

I do have a dimmer. I have it set to run at about 300 Watts. It’s about 22” above the canopy. That picture makes it look high. I’ll turn it up later, perhaps, depending on the temperature. It’s perfect right now with the vent fan turned down. I love the strips and being able to have a light that is ...

Why don't you want to use a potentiometer ?

I like the idea behind IoT that is why I would like to have a modular network of sensors or many arduinos as clients and a RasPi as a broker/server. Stealth is a must. Here are screenshots from my phone for my lab. That's the EWelink app for the Sonoffs. You can see that the garage is cool and humi...

I set up my android phone webcam to detect motion. There is too much motion in a grow lab. I turned it off. Sound detection too.

What's that dimmer ?

Nice light ! I think the holes are a good idea- but you would need many more, and much larger to contribute to airflow.
