Recently upgraded to Sun Systems LEC 315 Ceramic Metal Halide HID grow light. I've got a small short grow on, 3x3 scrog. Two strains, Barney Farm's Pineapple Chunk and DP Brainstorm. Photos. They vegged for 3 months (45 inches or so) next to a Dinafem Blue Kush Auto that dropped 5 zs, 1x3 scrog, 24/0 the whole way. Ordered my light from a local distributor and turned my plants sideways during transplant to lay under my screen. From a 3 to a 5 gallon dirtpot. It was on the west coast, Washington State, and shipping was truck freight because it was on a pallet. So two week wait for the light, when I was expecting just a few days, global economy and all that. But two weeks more veg for everything under the screen to turn up to the light anyway, lotsa tucking and plucking. Went 11.5 on, 12.5 off and the first pistils popped April 1 two days later on the storm, and one more day for the chunk. My light came in two weeks to the minute and it was hanging that night, which was two days after the chunk popped. So that's what I'm working with. No comparisons unless someone else jumps in. These have been out a short while and there's not much out there, but what little is is pretty positive. So hopefully this will be a good place to reel it all in. 3 days have gone by and those few scraggly pistils are little white spiky balls now, almost fluffy, but not just quite. Maybe in the morning.

I'm a pretty mad gardener in the yard. 30 hibiscus and a dozen hydrangea, another dozen clematis. But I'm new to indoor and cannabis and for witw posting in forums. lol. Would love to see some interest, I think some good points can be raised, because face it, alternative technologies are not just competitive, but are even outpacing HPS setups. Probably most true for the small grower like myself, 1-6 plants.

I'm sure I'm like everyone else and has read and looked up all kinds of light info. Next post I'd like to talk about the reasons why I chose this light, which is a bit of a mashup of all that reading.

BTW I paid $500 total for the light and picked it up at the store. I had ratchet hangers but if you don't, you will, not included. Thanks guys at Boyer Indoor Gardening for your help. Appreciated. And I need to learn how to start an album to post pics. Gotta move that up the list. Smoke em if you got em.
 
Good luck with the grow btw been looking at pineapple chunk for next years selection wish i got them this year. You can start an album in your profile page just have to upload photos.
 
315w CDM is the best grow light there is. I've used them for a couple of years now. Maybe in the future LEDs might surpass it, but they're not there yet.
 
Heard a lot of great things about the 315cdm line, good to have a grower with such a light here. Cheers 81camaro:)

Best hid spectrum there is, the phillips 315w cdms for growing come basically in 2 main options, 930 and 942 bulbs. The 930 is intended as "Agro" light with more reds, the 942 is a fuller white spectrum. So far the performance should not be so different, however the 942 seems to produce more resin.

If I were to buy a lamp or two, the cdm would be my first choice, maybe supplemented with deep red leds.
Higher price but higher quality than hps.
 
316 watts to the bulb plus ballast losses, lets call it 350ish? 350 watts/120volts is about 3 amps. I'm on a 15 amp line and wont go past 7.5.
Checked your link. That's a 10 amp 1000 watt HPS not LEC. Light-emiting-Ceramic.
 
The Chunk is really something special. It was a pick-n-mix, but I believe it to be a very sativa leaning pheno. Might add a few weeks to the bloom but I'm sure it will be worth the wait.

Brainstorm is on the left, Chunk is on the right. Laying down the BS is in the front and the PC is on the back wall.

Is $500 high? IDK I suppose it's a question of value really. I do understand you will never work better than your tools will allow you to. So I tend to buy high grade when it matters. I'd like to cover this more.
 
Today, 7 days into flower.

FoxFarm nutes. 6ml Big Bloom, 6 ml Tiger Bloom, 4 ml Cal-Mag, 4 ml Hi-Brix Molasses, 2 ml Silica Blast, .125 grams Grotek Monster Bloom. In 2 liters well water. Each. How do they look?
Pics taken under the LEC315, on an Iphone5, no filters.

I hear you....... Thanks for posting this, it got me intrigued and after done hours reading up now I'm more than intrigued..... Here is 2 excellent reads on the cmh 315

I then went looking for a Euro plug & play fixture with the cmh 315......does anyone know of any, except for the Dimlux Expert which is £500 plus and the D-Papillion 315 which is even more?

And really asking a lot now, if there has been any issues with RF interference?
