Not disputing that, even with salt-based hydroponics microbial life can be useful and beneficial. However sometimes it isn't desired or required. Car's can be faster with turbo's over high compression. Different performance characteristics though. This thread isn't about soil vs hydro, I'm not interested in which is 'better' since 'better' is a subjective term. Let's keep this conversation on COB's now.
My final paper for Biology of Ecosystems was on (the dangers of) GMO and everything was cited. I don't want you to think I am spreading misinformation.
Ahh good call didnt think of that. Ya it would be in the tent.
Yeah tapping for screws for the COB holders. I just have my COBs kapton taped on right now on my two modules but want to do COB holders with new COBs.
Not sure what you mean either haha. I dont want the grow bags sitting in their runoff and I hate having to pick the plant/pot up out of the saucer to dump any runoff out. With a short height-wise drain table I can just put a container to catch the runoff coming off the table when I water and let it drain for a bit into a shallow container I place on the floor just outside of the tent. Once its stopped draining I can take and dump the container of runoff and zip the tent back up.
Man this thread is moving fast today. Here's an article about the evils of PVC, specifically shower curtains.
Thats a bit off putting. Not sure what to use now, I was liking my free drain table idea.
I'm sorry. I was honestly thinking earlier, if it's an old shower curtain, it's probably about done off-gassing. Plus it's going to be at the bottom of the tent, and wet. I think it will probably be just fine.
I like the cleaner look of the modules with the holders and it just seems more "properly" done when using the COB holders. Also if I were ever to sell the used COBs when something new and drastically better comes out, they would be in nicer condition if I dont solder wires to the contact pads. Or if I wanted to sell the complete modules, COB/heatsink/driver, ready to plug and play I would be best off with the COB holders, not many people would want to buy an LED light with taped on LEDs I dont think.
I've been tapping with a hand held drill, hand tap, and a punch to start the hole. Really really fast and easy!
I ran into that problem..
Hey Rrog, you get much higher thermal transfer with a lapped(true flat) surface and the thinest possible TIM. I can't see a taped COB as giving the best thermal transfer.
Deleted my reply, if anyone wants to talk about it further we can do it over messaging. I'm being one of those douche bags that makes compiling info about LED's difficult for newbies. Sorry...
I dont have a drill press so that is what I was going to do too. Mark holes and center punch then drill.
