if it was my tent i would use 2700k cobs and keep the 4200k lec in there full cycle.I’m adding some extra lighting (COB LEDs) to fill the corners of my tent, and increase amount of light. Trying to figure out correct spectrums.
Currently have:
-LEC315 (4200k veg bulb, 3100k flower bulb)
-4x4 tent
Adding:
-4 drop light COB LEDs for corners.
- Either 3000k or 3500k
Ideally, I was thinking I’d turn the COBs on a few weeks after popping seeds, and possibly slowly turn up brightness until I got to the flower flip, then full power I switch my primary LEC BULB to its flower bulb at this time). If I was only using the COBs for flower, I’d just buy the 3000k. But why not get some extra light in veg too? Which is why I’m considering the 3500k COBs.
I’ve heard that the more far red spectrum of the 3000k (600-660nm) can cause stretching in veg.
I was curious if you all think that the extra red of 3000k is THAT important in flower? Or if I should just get the 3500k COBs, leave them on almost the whole time, and just worry about the color spectrum coming out of my primary LEC light?
Whatcha think of these dumpster finds?I’d go with 3500k. I like a more white/blue spectrum and have had good results with it.
Back in the day when most were running HPS I was running a conversion bulb at around 4000k with great results vs the 2700k hps I had been running for years. But that’s me.
In fact I’d have no problems running upto 5000k and will be here shortly. It’s to supplement my vispar burples. If I was running just cobs and no burples I’d run as close to 4000k as I could. 3500k is the closest I’ve seen.

4000k recessed can lights!! Scooorrreeee
Nope .Led. Thats a diffuser I'm gonna take off. Now I'm debating whether to buy a 4x8 tent or build it out of osb. 10$a sheet x 6 sheets. 2x4s around 30$, I HAVE HINGES ANF HARDWARE. I'm doing a coop grow at a friends. Is my 1000w hps too hot for a 4x8 tent? Even if I turn down to 50 or 75%?Ya know spectrum wise I love it. If those are led then you scored big time. If they are halogen lights tho then it’s probably not much more than a heat lamp.
I used to flower with 4200 or 4700k conversion grow bulbs. Either hps to mh or vice versa, it’s been years so I can’t recall which one has the cap.
Anyhow my buds were the frostiest they ever were after growing years with straight hps. The plants stayed a little more compact but flower, terp and resin production were the best I’ve ever had.
In fact I want to get a 4000k panel to go in between my two 3000k panels on my quantum board. I think the extra blue spectrum will really bring out the resin.
So those also must be 120 volt supply, though mounting heat sinks to keep them cool enough may present dilemmas, and safety may also become an issue...Whatcha think of these dumpster finds?

I'm stoked .Ive been eyeing em. They made it into the dumpsger ..now there all mine
Heat sink included . and yes 120So those also must be 120 volt supply, though mounting heat sinks to keep them cool enough may present dilemmas, and safety may also become an issue...
10 wattsInterested to see what they draw current wise, do you have access to a amp meter? Or is there something on the housing indicating current and therefore calc’g wattage?
Wondering if someone with at least minimal skill with hand tools and wiring could maybe retrofit a nice little COB chip in those housings. Guessing you'd have to update the drivers, but they look like cool housing/heatsink assemblies for some DIY COBs. Not sure if the project is as relatively simple as it seems, but it's the first thought that came to my head.I'm stoked .Ive been eyeing em. They made it into the dumpsger ..now there all mine
Should I sell my 1000 w adjustable hps for 75$ to a friend and buy 2000 watt led for 119$
Bestva 2000w?
