I've been rockin' Advanced for a while now and already have them and I've already got the mover, too. I'm stoked to see your results! It'll kinda be like a lookin' into a crystal ball for me!
So they averaged 13" on trigger day. They are now averaging 18" and the lights are 12" off the top of the plantsHow tall are the plants currently (above the soil) and how far above the tops are the lights now? Do you recall how tall they were on Day 1 of flower? What strain(s)?
Forgot to ask, your 3ft plants, are they foliage and bud to the bottom or do you train or trim them to keep the production focused near the top?Thanks for the info, dunit.
I run CO2 propane burner at 1200ppm and plants finish around 3' tall.
I also contacted the 357Mag guys and was recommended to cover a 4'x8' table with three of them. I was told this would outperform my 2x1000W which cover this area currently. That would be 2000W reduced to 1071, almost half.
As for the medium I am thinking replacing the rockwool cubes with Fytocell in pots, flood and draining, like Al B Fuct.
I trim the bottom 3rd of the plant, but I still get a thick canopy with a bit of lower branches in each 4x4 36 plant area.Forgot to ask, your 3ft plants, are they foliage and bud to the bottom or do you train or trim them to keep the production focused near the top?
Interesting, I will ask the 357mag guys what is the actual average wattage draw on this light and post here. Keeping the HPS idea is good, but I do want to cut wattage as much as possible. My electricity company now offers a "service" of checking annual consumption of ANY address online.Something to keep in mind also is that LED's don't actually draw the rated wattage. Has something to do with as you approach the wattage threshold for an individual LED it gets less efficient at producing light so they basically underdrive them. For example Stealth Grow's 602 actually draws 350Watts. If I had to hazzard a guess I'd say the 357 probably draws 200watts so in actuality you would only be using 600W to replace 2000. The only drawback of LED's, if you can call it that, is that they hardly produce any heat. I am using two 357 over a 4 by 4 area (which is definately overkill and I'm gonna expand to at leat 4 by 6 next grow) and a propane burner for CO2 in a fully sealed and insulated room and I have to use a small space heater to keep the temps up. I am on a concrete floor and if I threw down a sub-floor I could probably lose the space heater. Sure is different from the old days runnign 4 1000w HPS's and needed 12,000 btu's of air conditioning
If I was growing in a cooler climate and heat was an issue I might look at running one 1000wHPS in the center of the table and a 357 on either side which would still be a power savings of about 600W and would probably keep the room a balmy temp. Just an idea if you are looking to expand in stages.
Thanks brolooks nice dunit......I am impressed
Wow that's quite the service....so much for privacy! I'm all over the full convert to LED's but if you get stuck looking to add a heater and waste power then why not stick with the good old heater that actually throws some light aka 1000W HPS..lol.I trim the bottom 3rd of the plant, but I still get a thick canopy with a bit of lower branches in each 4x4 36 plant area.

That does make sense, however it would not resolve my night time temp being too low, if that should happen. Although I guess that can come down to 18-20 Celcius at night without issues.I'm all over the full convert to LED's but if you get stuck looking to add a heater and waste power then why not stick with the good old heater that actually throws some light aka 1000W HPS..lol.
I hope I get a BIG tax refund......That does make sense, however it would not resolve my night time temp being too low, if that should happen. Although I guess that can come down to 18-20 Celcius at night without issues.
Got a response from 357Mag guys. The actual draw of the Magnum is 180W, so you were pretty close in your estimate. That is pretty incredible when compared to 1000W HPS lights and if claims are correct 3x357Mag > 2x1000W, or 540W LED outperform 2000W HPS.
Well from a light spectrum scale those ratios make sense. If you look at the output of a 1000w hps the peak, and something like 75% of their output, is in the yellow/orange spectrum that the plants can't use. If you could eliminate that waste then you could accomplish the same thing on 25% of the power. That is supposed to be LED's claim to fame and I guess I'll find out in about 6 weeksThat does make sense, however it would not resolve my night time temp being too low, if that should happen.
