Can you refresh my memory, please: you have 12 plants total, in a 4' x 4' area but were planning to cover a 6' x 4' area with those 2 lights?

12 plants is what I want to be able to flower, so it sounds like I need to work on plans for a 6x4 flower box and possibly 2 of these, if I like your results. If not I will just get another 600w HPS to go with my current flower rig.

Yup! Plants didn't get quite as bit as I was anticipating so covering a smaller 4x4 area but could definately raise them up and cover a slightly larger 4x6 area

I know I have asked this in the past, but can you update these details when you have time: How tall are the plants currently over the top of the soil, and how far above the plants are the lights? I use LST/CCOB to keep my finished plants around 24" tall and my air-cooled hood about 12 - 18" off the tops.

I'll measure them again tomorrow and see where we stand.
 
Read through this entire thread. Placed my order for 1 357 I should have it in 2 weeks. Just In time to put my 2 ladies I've been LST'ing for a month now into flower. I can't wait to see the results in my 3x3x5 cab.

Well I'd have to say that a 3x3 space will give you phenomenal intensity with one of these lights. Should get some heavy buds out of that. Post a journal :-)

Sick brag. I really want to get 3 of these and a 4x8 tent but dont think I can afford to do it all at once. I might DIY a flower room to save a little bit and get 2 of the 357's to start. If I only get 2 of them I will probably run them with my 600 hps until I can save for the 3rd 357.
So apparently I'm not so swift on the comp today....not sure if that was you who PM's me but seem to have deleted the message while trying to reply.

the website I ordered from was www.357led.com

I would totally put a 600HPS in the center of a table and run the Magnums on the outside. Not sure how your room is for heat but these lights run so cool you may need to supplement with some heat to keep the temp up to optimal range so a 600HPS might be the ticket for that.

I used to run 3 x 600HPS's over a table so I think I've got a handle on your set up

Yes I definatly start a grow thread once it arrives. My 2 ladies is veging under a bunch of cfl bulbs. The 2 ladies should be spread out nicely to cover the whole 3x3 space when the 357 arrive to put tge ladies in bloom. tons of bud sites right now so i cant wait to get 1st hand results of dried led nugs to blaze on.

at this point in flowering how do you think they are looking compared to what they would if they were under 2 x 600w hps?.

So I see that you are using a coco/per/comp mix for your medium. Considering the differences with LEDs and your experiences thus far, do you think that is your preferred medium under these lights? I'm just curious about drying time between feedings and whatnot...

Well the coco does make it incredibly porous and you can hear the air getting sucked into the medium when you water. Almost sounds like rice crispies :-) Other than when I've had temp issues (too low) the growth has been explosive and I'd almost compare it to hydro. Anyway, one of the things I want to do is run my mix against Promix for a round to see what the performance difference is. The plants certainly don't dry out nearly as often as they do under HID so watch overwatering. I'm running 1300ppm nutes

How many days does that strain flower for?
Suppose to be 8 wks. Just had a buddy come down with plants from the same mum and seemed like they were finished at 8 wks but not sure how his weigh in is gonna pan out. He was under 1000HPS and had 16 plants in a 4x4

Looking good man. I'm gonna be switching to LEDs once the summer heat comes on. I'm following a couple of journals to see if I want to do Blackstar or shell the extra for ISIS/Magnum. I'll have at least 200w of supplemental non-LED lighting so I'd probably be alright either way. Sub'd for comparison though!
