afternoon afn

i hung cobs yesterday ..

Here electricity is very expensive ... we pay not $0.15 per KWh but $0.58 so any save on electricity is huge ... just going from 300+ watt burple to 4 1212 220w will most def be notisable on the bill

More bud, for less money! Win win!

I'm going to leave my system as it is till I can afford COB's. I have a 4 bucket top feed + undercurrent RDWC in the works. I have all the parts but the lights and a fan or two. This summer, the COB's shall be mine. I will be doing comparisons for sure. I have plenty of seed now to do it. I don't have fancy PAR meters or killowatt meter for the outlets yet either. Soon.

Right now, you'll still spend more up front, but the savingsin power and consumables that arew no longer needed is a secondary benefit. If you can pull 1gpw with HPS your near the top of your game. A newb who does things basically right with modern COBs for lighting is going to see 1.25gpw easily. It looks like Big Smo may it a pound or more with just 4 cobs running at a total of 220 watts! That over 2gpw!

It seems to me that unless I can recover the cost quickly with electrical saving (2 or 3 grows) I am not ready to invest in COB yet.

Cost was a big factor for me too - I survive on a disability check of about $750/month, so cheaper the better. I did the math, and the lights I was *going* to buy (Mars Hydro 600W x2) would have cost me *three times* what the autocobs I just ordered will in electricity each month, with less efficiency and an inferior quality of light. Now, I have no idea what yield I'll get from them, but honestly it seemed like enough of a no-brainer to me to go ahead and pull the trigger. Just my two cents!

When running LED you want a minimum temp of 82 degrees. The hps it is 75 to 78 degrees. Make sure to keep the ambient temps up for best results with LED

Thanks for this!! I was concerned I was getting warm with a range of 72-81 @ 45% humidity, but it looks like I'm butter!

Sorry I had to step out..

My eventual goal I suppose is a perpetual. Use my 3*3*5 with LED for seedlings and veg, then set em under some prime light in a bigger tent.

I am also a newbie and working with new nutrients, so I've got some roads to travel, but daydreaming and planning are what make the drive fun *strreeeeeetch for that analogy* thanks all for the input!

@BigSm0 - I kept putting .com and high-phons... Haha, I've got you in my .net now!!

Hps and a REALLY REALLY top notch grower 1-1.25 gpw. Average grower and COBS, should see in excess of 1gpw, likely 1.2 to 1.6! And even pro growers in the commercial area will tell you COB led bud is superior to any other in quality and potency. With some experience using these lights, 2gpw is well within reason. And there are guys out there exceeding even that.

My test of Big Smo's Autocobs is on the extreme end as I'm usingf just two cobs for 2 plants, and the plants are in only 2 gallon pots. I'm hoping for 60g per plant, maybe a tall order in such small pots, but regardless, it should show the potential waiting to be unlocked! I was afraid to use my 3.9 gallon pots in that little tent.......lol!

@hippy71 did a 2gpw grow using my new light

Remember to factor in that the savings go a little beyond just the watts at the wall of the lights themselves. Since they are higher efficiency and using less watts, they are also producing less heat. So less ventilation needed, less A/C to counter the heat generated by the lights, etc..etc.... :smoking:

Wow it's hard to keep up!
@BigSm0 has the perfect light in my opinion. It is well made, the engineering and components are top notch. The sizing is also great; being able to add remove and adjust is just too perfect. @pop22 I totally agree with you. Wattage is not the proper way to discuss these things. Real usable units of measure as you stated are the only true comparisons. The proof is in the putting (or is that pudding, mmm love pudding) though so without getting too technical the way that @BigSm0 is doing with his grow of x amount of plants in a common size tent with x amount of his lights give folks a good idea what to expect. Certainly does make for simpler.

I think it is important to factor in lifespan as well. How many HPS or MH bulbs will you need to cover the lifespan of the average COB. That is a big savings.

COB's are not for everyone. But for those of us that see the light...
