Second round of Nirvana seeds in soil. Bubblelicious, Sterling Haze, and Aurora Indica. (4 plants, two buds from each) In the light (LED, white spectrum) they look like a lot of white hairs. In pics... well, here they are. Are these ready to harvest? Am I a little early? Little late? Thoughts?

1050mA is a good medium between efficiency and number of COBs needed. If you got $$$ to spare and heat is your ONLY though, go for the 700mA. DL the COB calc and get to playing with it!

It's... this one... hopefully the link works..

::cries uncontrollably:: City living. I can eat 30 different cultures' foods at midnight, but rent/electricity I pay out the butt.

I'm absolutely fine with moving to new tech, but I'm trying to find efficiency numbers for all these cheaper COBs because I pay almost $.30/kWhr. Paying an extra couple bucks to save $$$ over the course of a year is absolutely worth it. Is there a chart comparison for these? Currently I'm...

Why is this chart and the one in https://www.rollitup.org/t/high-end-cobs-vs-2-cobs.941089/page-2 different?

Glad it helped! In the calculator it has the COBs' efficiency in one of the lines. You can just pop through them real quick to get the numbers. Cree COBs are pretty great when running at low amperage. Vero29Gen7 are more efficient than Cree at higher amperage (and cheaper), but... you want...

I was looking to set up my veg tent with these. Good to know these extra tidbits.

You got it. You are using that calculator right. At 2100mA it's 4 COBs for 844.63PPFD and 5 COBs for a 1057.35. And you'll need to get another driver and space them to avoid hot spots. (you seem to have all this under control already) If you had infinite cash, running 12 COBs on a HLG-320H-C700...

Using 9 Citi1212's at 1400mA on a meanwell driver will get you these stats: 1212 3500K80Min 9 COBS @1400 mA ON 1.813 PROFILE HEATSINK 25 SQ.FT. CANOPY 94% EFFICIENT DRIVER @10 CENTS PER KWH Total power watts at the wall: 502.84 Cobs power watts: 472.67 Total voltage forward: 337.62...

So, your current PPFD is talked about in here: https://www.rollitup.org/t/inda-gro-420-pontoon-ppfd.877463/ It's like 164, which is pretty low though I'm guessing it's because that light can't really light the whole 5x5 very well.

My opinion: *ChilLED boards are fucking amazing, both in spectrum adjustability and efficiency. You can get a kit or buy your individual components, but he tells you exactly what everything is. https://chilledgrowlights.com These are a little more front end cost, but you save electricity every...

No worries! Just start a whole new thread in the LED forum and people will jump on to help you. Thanks for being thoughtful! (And I'll delete my response when you do, and respond to you in your new thread. (:

I don't want to step on anyone's dick/tit/other, but there is a forum for asking these and you will likely get more answers. This is the calculator thread.

And are you considering efficiency or just looking for cheap front end cost?

Does the calculator get updates? I would be happy to figure out how to add new COBs and shit, QBs and ChilLEDs and driver info to this. This is an amazing resource and I would contriboot. (:

New MA commission stuff going on? Just got "We need your help to make sure the Cannabis Control Commission is accountable and efficient! Please call House Speaker Robert DeLeo at 617-722-2500 and tell him the following: (1) you want to keep the Cannabis Control Commission under the control of...

I JUST switched over to Jack's321 and I love the price/ease/control. I also have not chosen a bloom additive, but I need to soon. I'm loving the dry nutes, though. Thanks ttystikk.

Can you post a pic of your Bubblelicious towards the end? I want to compare to see if the pheno I have here is crappy.
