Hello everyone, anyone who followed my last LG/Top LED grow will know I wasn't pleased with the results.

Those LED's will be used in my veg/clone/seed cabinets but for flowering I wanted something with a little more "punch".

After looking around and doing a lot of reading, my choices came down to 2 options:
DIY LED or
This LEC Sun System with the Philips Elite Agro 3100k bulb (930)

So this round I'll be running the CMH setup while I build out a couple of 100W DIY Creee CXA-3070 "panels". It's summer and I keep pretty busy so won't get around to finishing the DIY LED panels this round, but more to play with next round :)

Here's the setup for flowering this round:
Plants were vegged @18/6 for about 8 weeks, stretched for 9 days @14/10 under my 300W actual draw LG LED panel and 108W of side LED Tubes. Switched to the CMH fixture and 12/12 on 6/29/2014, Day 0 for reference/counting purposes.

Plants/Strains/Footprint:
3 plants running in approx. 30" x 36" footprint. This will likely grow slightly as they're still stretching but they're pretty well done. Wanted to try and keep this to 3x3'. The 3 plants are in 5Gal Root Pouch fabric pots. All 3 are looking nice and healthy, beginning to show lots of bud site development.
  • 1x Jack The Ripper (JTR clone)
  • 1x Blueberry (BB seed)
  • 1x Pure Power Plant (PPP seed)
I had 1x BB and 1x PPP turn out to be males, they went into my breeding tent last weekend to collect pollen. Will use them and some JTR and Ace of Spades pollen to try some interesting crosses with these :)

Soil:
50% local Triple Mix + 50% PRO-Mix (I call it semi-soiless if that makes any sense)
I like this mix has worked very well. It contains some nutes in the soil mix and I supplement it with AN Sensi A&B Grow + Bloom nutes. I like this mix in that it's not solely reliant on synthetic nutes and I don't go over 600 ppm on the nutes. I "flush" them every 2-3 weeks, not a real flush as I don't believe in flushing, just give them water only with a good run-off every once in a while and let them use up any excess nutes to reduce build-up and avoid lock-outs.

Pots:
5Gal Root pouches. I switched to these last round and they seem to do exactly as-advertised. When I pulled the last round, the whole ball of soil came out in one piece. Essentially, the root ball filled the pots. They were 3Gal pots and handled one plant that got to about 40" tall, no issues with root binding or the like. I'll be upping the ante here betting the 5Gal pots help a bit with production vs. the 3Gal pots last round.

Lights:
The LEC Sun System with the 315W Elite Ago 3100k (930) CMH bulb. This was purchased as a kit with a very nice vertical reflector. It pulls 334W at the wall @120v. This is currently about the only "kit" available that runs at 120v. Haven't pulled it apart, too new, will at some point to verify what they're using for the ballast. What I can say about it so far is that it runs surprisingly cool for CMH, and as quiet as my LED panels. At first I thought it was running hotter, but after moving the temp sensor to match where I ran the sensor with the LED panels, the room temps are staying almost identical as when I had 408W of LED's running in this room for 10 days @14/10. So Watt for Watt it would be slightly hotter (3-4F) but really quite manageable for CMH. The hood stays cool to the touch, even at the end of a 12/12 cycle, impressive. You can feel heat escaping through the fins on the ends of the fixture but not much more than putting my hand over the LED fans. After running it for a few days, all I had to do was adjust my incoming/cool air to 1/3 throttle on the variable speed controller to maintain temps where I want them (78-82F). The specs on these bulbs are about the most efficient out there right now, they have, on paper, some fantastic specs all-around. Efficiency, colour chart, bulb life, they just look awesome for growing mj, let's see what they can do! :)
You'll see a couple of side panels. They're 28W 2700k, LED Tubes, they pull 27W each at the wall, total of 2 per side = 108W. Just trying them out on the sides to see if they make any difference to the lower branches/popcorn, not expecting much but I have them so may as well run them.
Here's the specs on the specific bulb I have in the LEC fixture:
  • Part No: 928601167102
  • Name: MasterColor CDM-T Elite 315W/930 T12 U P 1CT
  • Colour: Warm White 3100 K
  • Lumens: 36200 Lm
  • Luminous Efficacy: 115 Lm/W
  • CRI: 92
Ok, nuff said, lets grow some MJ! Questions/comments welcome, I'll be updating the thread with pics weekly.

Here are the pics or it never happened as they say :) The setup, room and ladies as of last night:

Looks really good..high tech setup

Great decision on the lighting I think. If you ever finish the leds they'd probably compliment the cmh nicely

Hey thanks positivity, I do look forward to getting the Cree panels built, just chose a bad time for taking that on, time, time, time :( But yes, I think they will be a very nice combo eventually. Kind of want to see how these lights fare on their own this round though. They're a relatively high cost fixture/light setup ($500) and the footprint is just about the max they recommend so I'm interested to see what they can do more or less on their own. I don't think those SMD LED tubes will really add much but they do light up the bottom/sides nicely from a visual perspective, whether they have any efficiency to actually grow any bud down below remains to be seen. Cheers.

Im subbed for the ride. I want to see what this light can do. I believe its an all in one unit with no remote ballast, always handy.

Hey welcome aphrodisia. Yes it's one unit, everything nicely packaged, no remote ballast. Not cheap but when you look at the specs, between efficiency and rated bulb life, and it's supposed to equal or better 600 hps, pulling 334 watts at the plug including the ballast, relatively low heat and as quiet as my LED panels. No complaints on pulling the trigger so far. Looking forward to seeing what it can pull from these 3 plants :)

Bubbaengineer.......has a run under it

Love me some cmh grows.........
Oh good, was hoping I wasn't a pioneer, I saw some older posts but hadn't found any current grows. Did a search by member and general search in the forums for bubbaengineer and didn't find anything though...

Def subbed for this GroErrr! i think you'll find you made a great decision
Thanks Coco, pumped about seeing these things grow, those chinese LED's were starting to give me a bit of a complex ;)

I am alway's watching. Go Groerr,. I like the way it's going so far.
Cheers medicine and thanks for following along. The LED's brought them to this point nicely, now it's time for these girls to flower under the big boy light ;) They were stretching nicely under the LED's but the last 6 days under the CMH have stretched them another 4" or so, long way to go yet, as you know 8 weeks is a lonnnng time...

Nice grow will follow along. I see 150 watt cmh bulbs are reasonably priced in the eu. Anyone tried a couple of those?

Hi ballist, thanks for popping in. Haven't tried anything but LED's indoor so Im a total newbie with CMH. Maybe someone watching can chime in on regular CMH bulbs. Some comments below on what drove this setup and why I believe the cost is worth taking the chance on it. Only experience I have after trying some low-end LED's is that not all technology is created equal and typically the old "you get what you pay for" stands true. Not sure whether that transfers to CMH but I'd bet it does.

My decision on this particular setup was based on a couple of major factors:
1) Efficiency. From a power draw perspective, this fixture, with this particular Philips bulb, is supposedly equivalent to a 600W hps. Considering the combined bulb/ballast draw, usable (by plants) spectrum, lumens/watt, CRI, I believe it as HPS wastes an incredible amount of energy which goes unused, in addition to the heat generated which has to be dealt with and adds cost/hassles. If these ballast/bulb combos perform as advertised, they are equivalent or better than many (other than maybe well designed/driven DIY LED's using the high-end chips like the Cree CXA series COB's) LED's when it comes to efficiency. For the price per usable/efficient Watt (assuming they perform as intended), they are also less expensive per Watt than even mid-range LED's e.g. $500/315W = $1.59/W on initial purchase. In comparison, it'll cost me about $2-$2.50/Watt to build an equivalent efficiency LED panel using the Cree CXA-3070 COB's. These bulbs are also rated at 20,000 hours, or in my case up to 4.5 years running them 12/12, 365 days/year. Of course there will be some degradation and I'd likely switch them up around the 2 year mark barring any other failures. For $90 or so replacement bulbs that's pretty good value/efficiency, in my analysis I didn't see anything out there more efficient than this, if of course it delivers the goods.

2) Heat. I have a relatively small flower room (4' W x 9.5' L x 7' H) and summer temps can be in the 85-95F range. I'd eventually like to run about 600-800W total in this area. While I could run a 600W or 1000W HPS, 2 of these CMH bulbs would surpass the usable energy/light of the 1000W HPS, and run cooler to boot. I'll likely run 1 of these and 200-300W of high efficiency DIY LED's and easily manage heat from those + get more production if they perform as expected.

Cheers

I love reading intelligent people's posts. Makes me all happy inside...
Ha, not sure about that but thanks for the kind words :) It's all about eventually making the best use of available space. Eventually is the keyword, not exactly maxing out my space right now but I'm in no hurry. One decent run is about all I'd consume personally for a year, anything beyond that is a bonus...

I expect you'll do well

I considered one, but it was not available assembled and ready to go/grow prior to me hooking up with BML

How big a space is it supposed to cover?

Hey Pet, thanks they look pretty sweet on paper. This (LEC) was the only package I could find available in 120v to run these bulbs when I looked around for them. There was one other bare-bulb DIY option I was going to try, which looked even more efficient but the CeramaTek 375W ballasts are currently only available in 240v. Plus inquiring on them with the manufacturer, I was not impressed with their responses and confusion around the 120v option, they basically said that you could run them at 120v but they didn't/wouldn't support them. So these were really the only option to run them on 120v unless I missed something in my search.

They're supposed to cover a 3x3' well. Down the road I'm thinking a 4x4 with these in the centre and multiple DIY COB LED's "panels" to cover off the gaps/extend the footprint. On the DIY, I'm thinking 4x 50W panels, instead of my original 2x 100W, will be more flexible for supplementing or filling gaps.

Apologies for the late update folks. Turn of events when I was updating pics last night. The Blueberry that I had questions about turned out to be a freak'n male :( That's 2 of 2 BB's that turned out to be males :( Not a happy camper.

I had moved the first one into my breeding tent a week ago and it's full-on flowering and almost ready to collect pollen. This second one in the flower room had started throwing out what looked like fem pistils, completely different than the other pheno and late to show any signs of male flowers. Shit happens as they say. Just had to concentrate on getting this mess sorted out last night, no problem as it was just developing sacs but had to cull it, no room and I already have a male flowering in the breeding tent so just trashed it, and the 4 clones I had coming up from it :( I have another 7 viable clones from the JTR and PPP fems plus a Blue Dream fem seedling coming up so no shortage of plants for next round.

Will get some fresh pics tonight and carry on with the Jack The Ripper and Pure Power Plant for this run in a 2x3 footprint. At least those 2 are fems and are developing nice bud sites already. Always a bright side, just can't think of one for this turn of events ;)

Ok, weekly update for Day 8 of 12/12. As mentioned above had a bit of clean-up work last night. Forgot I took some shots after the clean-up, late night. There's one up-side to this culling of the BB male, better coverage for the 2 remaining plants, there's always a bright side ;)

So, pics going forward will be for the 2 fems left in there, a Jack The Ripper (JTR) clone, and Pure Power Plant (PPP) from seed.
Unfortunately these 2 were the smallest going in, but they'll produce some bud so on with the grow, will try to make the best of these two ladies.

For 8 days @ 12/12 they're looking well imo. Flowers are developing quickly, keep in mind that I'm counting from the flip to 12/12. I put them @14/10 for 9 days under the LED's to stretch them and get them pre-flowering. I find when I do this, besides stretching them, they begin pre-flowering. That makes the count from 12/12 pretty close to the seed bank recommended finish time. JTR should be 8 weeks total, PPP should be 10 weeks so I'll be harvesting these incrementally as they each finish.
The coverage in the remaining area of 2'x3' is awesome. All sides/ends are getting a ton of light. One thing I noticed with these lights in comparison to (LG) LED's is the penetration seems much deeper. You can clearly see light getting to the bottom and hitting the floor in between the plants. May be that it's white light and easier to see but it looks brighter all the way down/through the canopy. Should be able to validate later as the buds develop. I found the middle/lower buds with the LED's popcornish (and fluffy) beyond the top canopy last round.

Environment:
I've mentioned it in previous posts, these lights run surprisingly cool for this technology. They've only raised temps by 2-3F which was easy enough to adjust/manage by adjusting the variable controller for incoming air to 1/3rd throttle. Considering it's been in the mid 80's and 60-80% humidity outside since I turned them on, that's awesome. No worries with summer weather, was a bit of a concern going into this early summer. Keep in mind though, I just built this room and it has air conditioning being pulled in from the house HVAC system. Since I run the lights at night and keep the house at 68F for sleeping, any fresh air going into the room during lights on is 10-15F cooler than the flower room. So if I need to cool it down further or reduce humidity all I have to do is crank the variable controller and I get cooler/drier air in there.
Temps: Lights off: 70-75F, Lights on: 79-83
Humidity: Lights off: 55-58, Lights on: 46-49

Vertical SCROG?:
Oh yeah, one more thing Im playing with this round is the trellises you'll see in the pots. Saw them when picking up some stuff at the dollar store. They're not much different than the one's my grandpa used to make for his tomatoes, figured I'd try them. They're bamboo, about 28" high and the bottom 8" or so have 2 "feet" that stick into the sides of the pots. They make LST easier when needed in these fabric pots and I'm doing a sort of vertical scrog thing with them, guiding the main colas through the holes. Makes evening out the canopy easy, and open up the centre nicely to get lots of light down through the centre. I can tie the colas to the stakes if necessary and provide support when they get heavier. So far I'm liking them. Only down side I can see is once they're weaved through and they stretch out, they'll need to stay in there until harvest, but no different than a horizontal SCROG really.

Finally pics, here are the two remaining girls, group shots:

Oh, and the late blooming Blueberry male :( The first one just started shooting out male flowers, easy to see/detect. This one didn't show anything but what looked to be pistils until I checked them last night. You can see the "pistils" around the forming male flowers. In comparison, the last pic is of the BB male I moved into the breeding tent last weekend, it's pretty well ready to collect pollen. It's been on the exact same light schedule as the one I pulled from the flower room last night. Only difference between them is this one went 12/12 under the LEC, the first male went into the tent with LED's but was already clearly showing balls at the time... weird...
