Hello @GroErrOk, 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:

Thanks for the pos comments, those lights in the right conditions are awesome. Would like to see some others run different configs with them like SCROG, vertical, they should do really well in any style grow.
Hey thanks for popping by and glad you found it useful. Those trellises are really simple, why I like them. I bought them at a dollar store in the gardening section. They're like 3 for $2.50 or something. They have two "feet" sticking out the bottom that you just push into the soil at the edge of the pot, push to the bottom and they stay there. I put two per pot opposite each other. I originally got them for support and LST when I went to fabric pots, needed something and didn't want to drill/rip the fabric pots. Tried them in veg first and loved it and brought them into the flower room. They're great for LST early on, support as they get heavier, and somewhere to tie and keep the canopy even.
Cool! Thanks for the clarification. I'm gonna check them out, for sure.
At least it looks like, as far as I can tell, the ED37 aren't the ones listed in that recall notice at the top of that link. Because
Yeah that's another MH bulb, it's been up there for a while. Philips publishes any recalls on their web site.
That would be awesome, gotta get around to building some COBs, the two techs combined should grow great bud.
Hi ozone, thanks for the comments and questions. The last one (second unit) I bought on sale, I think they may even have one of those 10% off sales this week so it cost $448 + $68 shipping US, that's the economy option and about the cheapest they offer. Still cheaper than anything available up here, you'd probably be looking at $600+ CAD or more if you could find a dealer to order it in. I've looked around a couple of times, asked the manufacturer, they sent me to a couple of shops up here and those dealers didn't even get back to me with a quote so I stuck with growershouse. Just part of the problem being up in Canada, supplies, prices and options suck.Hi GroErr,
I've been doing research about CMH bulbs for the 5 hours and have seen many posts by you on this topic. Not trying to thread jack but simply looking for an answer to my situation.
I have looked at getting the Sun System LEC 315w as well but found the shipping to Canada to be $100! I noticed in one of your previous posts that you said you got it for $500 shipped, was wondering what you did in terms of shipping to get it lower.
I can't decide between the Advancedtechlighting's MasterColor setup and the Sun System. My only problem is my flowering room is only 2x2x4. I don't have anymore head room and I feel this will be an issue. Maybe I will just need extra super cropping or short strains.
Have you found any difference while doing research between the:
Argo Elite 930
vs
the one from AdvancedTechLighting, the Philips MasterColor CDM Elite 315 watt?
Other than that, it looks like an amazing setup you have going! Your abilities and setup has inspired me
Cheers,
Ozone
Good point, thanks for the input PSU, I hadn't looked at the Allstart's but a quick google found this 145w mogul base lamp, only comes in 4050k but that's fine, bare bulb and 145w might work in that space? I didn't realize they had such a small lamp in that series, going to look into it and may try that myself in my breeding tent, that would pop nicer seeds than my DIY/low-end LED setup in the tent
freaking insane!!!!Blue Dream got the chop tonight @day 56/8 weeks. Well ready, huge plant. Dry it this week and trim up next weekend. Had to break it into 4 sections to get it out of the trellises. Some good size buds and weight there, let's see where they come in dry
Posting chop shots, then bud shots to follow in a second post:

Agreed, huge plant! When I was taking the chop pics I was going to use a lighter for perspective but it looked funny/small so I used the party cup instead!
Thanks GroErr for the info. I already have a A51 RW-75 which I really enjoy. I think I will be going with the one from Advancedtechlighting and see how that goes. I have access to fresh cold air from outside so that will really help with keeping the temps low. I just have to research fans and ventilation as I don't know a lot about that. As for my box I think I may be able to push it to 5ft tall on half the tent and 4ft tall on the other half, ill just keep the light on the higher side. Might work out. Unfortunately its in my attic so a slopped roof.
A lot to learn from you
Oh I see, you have some additional space just angled, that may be enough with some good circulation to dissipate the heat. If you combine the A51 panel with say the 210w Elite Agro that should grow some nice bud and manageable without a reflector, the 315w may still be a bit much. Good luck, some great info and resources in the Grow Room Design forum for your ventilation options. There are so many variables involved but keep the following in mind and you can figure out the best options for your space. There are basically 3 ways to manage temps and humidity, bring in cooler/warmer/drier air depending on the season, exhaust warm/moist air, (usually both in combination), or equipment like an air conditioner/dehumidifier. Try and avoid the equipment, particularly in a small space, while it may work, it will take up valuable space and generate even more heat in a small space. Thanks for the props but remember I experiment a lot and screw up just like everyone else, carefulThanks GroErr for the info. I already have a A51 RW-75 which I really enjoy.
