Think we are all wasting our time on a lost cause with him. 900w and 10 oz hopes are miniscule. Got the results he hopes for using 900w using 190w, showed him my pics and still he's talking about vipar being a feasible option. Shit I could pull those yields with a 400w hps all day too...

That I cannot touch on. That's a subject I'm still learning with phosphors but from what I've read it doesn't seem anywhere near that simple if you're planning on attempting yourself. Though honestly imo from what I do know and/or have seen, seems it'd be pointless. Because COB, chip on board...

Depends. One thing that is pretty consistent is that flowering needs it's reds so given the SPD data, and CRI info we have with current leds it's pretty similar ti HID lighting. Veg you want a little extra blues like a MH so you use a 5000-6500K color temp. Flower only 2700-3000K. Both 4000-5000K

I don't have experience with the red and blues. But you're right on the whole idea. They looked at spectrophotometer data for adsorption peaks for chlorophyll a and b. Well a peak is truly only suggestive of just that a peak. But then those initial red blue onlys didn't account for other...

Similar experience my buddy had with htg except they kept fixing the lights for him. On 400w HPS i ran in a small armoire(2.5x3x6) back in college I was averaging pretty much the sane .7-.8 g/w. Used a 6" fan to cool that space. With the the 4x4 led tent and 650w only using a 4" fan and with...

Diy for the win. Imo

Ok. Hey want another LG portable ac. May still have one that works fine. Whatever you wanna pay, no bullshit, plus shipping. Have to make sure it's still at the shop. Buddy used it all last 2 summers no problem. He just doesn't need it or want to Fuck with selling it. let me know I'll check...

First off regardless of what lights you run you need to get out of that garage unless it's fully insulated and air conditioned. Then again I live in Texas so I simply couldn't fathom it. Even if your highs are in the 70-80s at most still not cool enough in that garage most likely.

Lol I try to not be an asshole and just shit on things. But I remember my coming of light to LED then the brand and product confusion I ran into as just about everyone else. If it weren't for finding A51 and DIY I would not have the same aspect on LEDs, regardless of accuracy. Probably would...

190 w compared to your triple wattage. Just a couple pics much more in my threads.

Looks more like my grow under the xgs-190 only...

Agreed for the most part SocalRob. Though I kinda see some of it as stern love. The warranties with a lot of those places like vipar are also pretty documented, and not very good. For instance I was going to start with an Apollo or blackstar or Vipar, because it seemed cost effective. But...

Just fyi. For the 3000k CXA 3070s there is a slight mistake the charts show Z4 as lowest bin and Z2 as mid. Just can see people hearing use higher bin not really understand the data then possibly purchase Z2s over 4.

In 2x4 two a51 RW 150s. But that's still couple hundred out of your range. Other than that DIY or CMH. Imo

One thing that will help just a little with the captcha crap is checking that remember me box when logging in. At least reduced the occurrence using TOR.

Are you doing ground up or going off previous DIY lux to par meters using layered filters? Thought about DIY. But wanted a calibrated standardized unit versus getting the quartz setup and other equipment to do myself. How will you be calibrating your sensor to normalize your data?

Here is a pic of the 20" bare underside.

I basically use mine just as a guide for light height and angle to try playing with spread over the area for a basic idea. Expensive way of going about it but wanted more than lux.

Yeah definitely not 100% accurate but better than the hydrofarm and cheaper than apogee meter with sensor. Just letting him know it was an option. would be nice to have a real deal spectroradiometer.
