I think you're gonna have to give me a COB building tutorial
Lol im decent at electrical and diy stuff. I didnt wana follow the band wagon and wanted to do something different. I chose the 10 watt chips because other led companies use 1w 3w or good ones r 5w chips. Figured 10 watts 12 volt chips and alot of em would be awesome and beneficial to use. And 12v power supplys are alot easier to find around. it was easy well for me anways to put the lights together. Im gonna make a new one this weekend with spare cob chips and a few of them blurple strips to go along with it. Just cuz im bored and need to build something. Been forever lol

Where did you get the chips? What are they?

Just curious, I've been seeing nice things with COBs. I've run 400w MH in veg and 2 x 102 w Mars Hydro panels alternatively in veg and not real satisfied either way yet. Im using a 2x4 tent currently, and I can get decent growth with a few quirks with the MH, but that's a fair amount of juice to run. The Mars panels had what I considered to be odd growth and less vigorous.

8 cobs at 40W each would fill that space well, do better than the 400 MH and absolutely destroy the mars

~$300-$350

Switching to high efficiency LED would allow you to lower the wattage to about 200w for veg intensity in a 2x4 tent, but... What kind of problems have you had with the MH? It should provide plenty of par for veg in that space.

You touched on one...cost to pump 400w 18 hours a day. Cutting back would be decent. Some of my percieved issue could be just inexperienced overreaction. I'm curious why when I run plants under the MH in veg, the centers on all the tops pale. As soon as I move plants to Bloom under HPS, the color returns evenly within a week. I don't get that. The growth is much better than CFL, flouros, Mars LED though. I haven't tried a high end bulb, I just use cheap Vivosun bulbs.
