The ladies look great so far. Good luck! How did you use the veg & flower settings? How are you handling cooling,ventilation & odor control?

My plan is to grow in a 48w x 24d x 78h metal storage cabinet (6 plants). How many magnum 357's for that size cabinet?

Id say 1 357 magnum would be good in that cozy lil space.

I veg with an ISIS 170 but similar set up for veg/flower mode. I alternated between full spectrum and veg spectrum every two days to keep them a bit bushier. Odor control I run a carbon scrubber on constant circulation inside the room. I run a sealed room with co2 and no cooling.

Each Magnum covers about a 3.5 x 2.5 foot area with major intensity and could ealisty cover a 4x3 area with slightly smaller plants or thinner canopy.

You could definately run one Magnum in your cabinet and I bet you'd have no heat issues either. Might want to look at a co2 tank system and run it sealed

So you're running around 6000-7000 watts for flower plus a veg room which is another 1600-2000 so I'm guessing its hard to fly under the radar with that. To get that kind of yield with LED you'd run about 4000 watts including veg which is way easier to slip by with. Would cost a fuckload to get up and running though.
Good luck amigo.
I dont have a veg room.. Waste of a room? I preveg for 7 days in a differnt location.
I put them in party cups for a week them move them over in boxes. Put them in 2 gallons and veg for another 3-4days. I spray twice and always have the sulfer burner on for 45 minutes before the lights turn on.
So your telling me you can get 10-15 pounds off 4000watts? Sounds to good to be true.
How you running your ppm with the pk?
I make my own power bill. I get to pick what its gonna be.
Im not new to this and do run 16000watts of hps. I just got a new place and in the works of setting up. Thats what i plan on running. The biggest one ive done so far was 10,000w. In the new place im gonna have 3 rooms. one 8 and two 4.
Btw i have grown Pk for the last year. Tell me a few things

Wow man! Thats a lot of power consumption! Im only growing for personal consumption so I cant even imagine doing something that big! Goodluck to you!

I just pulled .9 grams per watt. Was my first time running in coco and made some newb errors with that medium so wasn't a great run. Based on that alone I'd pull 8 pounds of 4000 watts and really feel I'm gonna crush that result this time around so I think 11 pounds off 4000 watts is doable.

I'm running 1600 ppm nutes alternating with water. You're obviously very familiar with PK what PPM you run it at?

I max my ppm at 1400 for the pk. I feed every time and go by days. not weeks.
I figure out what my ppm is gonna be for the week and break it up in days.
For each amount of days they drink that is how much they get.
Week 1 150 a day and week 4 is 200 a day.
I used to feed, water, feed. It depends how much they drink. I feel 1600 ppms at a time is to much for most plants. Depends on what juice you have. And what those ppms are made up of.
How fast are you getting .9 a watt?

Hey Dunit, your grow looks great! Just curious, why don't you trellis? That usually increases my yield...

thanks, ledshow

Hey D great job. Long time "traditional" grower, first time poster. Great to see that led's finally becoming a viable lighting alternative. It amazes me that 180watts can show that level of sustained growth on such a footprint. Anyways subbed and happy growing....

I have a veg area seperate so every two months. Gonna have an early and late flower kicking pretty quick so then every month. Gotta factor in the additional power of course but should increase efficiency

I can't cover a bigger area and I have great penetration with the depth I do have so don't see a trellis being all that advantageous. If I had a light with 90 degree lenses which covered more area but had less penetration then the larger, more even canopy from a trellis grow would be worth looking at.

Is their any truth that the flowering period is extended under led? Internode spacing and flowering in your pics tends to say otherwise. Maybe a first gen. issue; I don't know....

I think he's experiencing the opposite. Flowering seemed to start super early. He had buds forming in the first week or so

Seems like the older and some of the cheaper panels that only had red and blue spectrum experienced lots of stretch and delayed flowering. Most likely due to a lack of Far-red/IR in the lights causing poor Phytochrome response. Certainly not the issue with the lights I'm using :-)
 
i hate to sound uneduacated but there isnt any real exact specs on the wavelengths that come on those lights.. The website says 11 wavelengths but what are they? I just recieved 2 of those lights and put 4, 3ft tall GC's under one and 10 little 1ft's under the other. I want to do a little experiment before things get serious.. So my question is the diodes (there are about 6) that dont light up.. are those the far red humans cant see? and they are for real?
I usually grow under 400's and avg 4 plants per light so i know exactly what i usually get under identical circumstances and i always use the same strain. i will look into doing my own journal but i'm not familiar with that process. so do you mind if i leave a little of my own feedback with you? I know the GC is a 6 week strain and not a heavy producer but if i hit a 1/2 pound on 2 lights i will be sold..
