450w Led Or 800 Cob Led?

[No1up]

Smithsjunk, after toasters recommendation I began reading up on the QB boards. So far as I can tell they are the most current leap in quality, efficiency, up front cost, and long term cost. From what I can tell thet are week in edge lighting but can be fixed with extra boards. Also penetration can be added with optics. Full kits with optics can be had at a reasonable price. I'm thinking of getting the 320 board with optics or a cmh 315 for your grow set up I'd look at the cmh 630. The grows I've seen, and yields G to watts ratio are outstanding. Plants seem to really really like the cmh bulbs. I'm at a cross road with either one. Even after all my reading and searching I have not found a post with someone showing QB boards growing over a gram a watt. Where the cmh seems to do that and maybe even more. Idk, could be worth looking in to.

It doesn't sound like you're familiar with my gear. I'm running 100w Cree CXB3590s with Meanwell drivers. Not going to get rid of almost $500 in fixtures to start over with CMH. I'm just trying to decide whether I augment what I have or add more, if anything.

Thanks for the thought, though.

 

[No1up]

Why start over? Why not add to? A broader light spectrum hurt... Or am I wrong in this assumption? I very well could be, but I believe I read a few post with people mixing it up and having great results.

Too much heat and not enough room for both. Don't think the CHM will fit within the specs of my solar system either. I looked into CMH already.

Ah! Well you have a sweet set up as it is. I' l to see it completed... Something tells me it will never REALLY be completed lol. Constant upgrading.

Thank you.

I mostly rely on my outdoor grow but I'm interested in eventually breeding. In that regard, yes, I plan on upgrading to multiple tents. Maybe even a shed. I need to learn how to do an indoor grow first though. From my research, I have the right equipment, but I still don't know jack sh*t compared to most of the vets on here. Their help with the first outdoor grow of my own last year was absolutely invaluable. That, and all the mistakes I made. If it works out the same for my indoor this year (much trickier), I will be one happy camper with some dense, grainy, nuggs.

I looked into your CMH. I would have to run 630watts to get a similar spectrum to the CXB3590s at only 300watts. Don't mistake what I'm saying for intensity though, the CMH bulbs have that.

What kind of heat does the 3K produce. I'm running 3x 100w CXB3590 with good diffusers and active cooling. My 48x24x60 tent has hit 90-92F in 80F weather but I've been able to get it down to around 5F over external temps. At this point I don't know if I'll need any other lighting. Call me sceptical but I still struggle with the idea that 300w can grow more than a plant or two, if even that. However it does seem like plenty of light when it almost blinds me to check on them and they peg my cheapie light meter.

Do you think I'd benefit from the addition of a single, cycle specific board in addition to my 3590s or should I just pick up another 200w set of 3590s? This is my first indoor grow so I feel a bit like I'm shooting in the dark.

I currently have 12 seedlings in the tent. 4-6 Will be going outside to leave me with 6-8 in the tent before any culling. Can I get away with 8 under my current lights or should I reduce to 6, or even 3? 4 are fems, so the standard odds are that I'll get 4 males to cull. I've taken measures to decrease those odds but I've beat the sh*t out of them pretty good trying to dial it all in. All my effort may be in vain but I don't easily give up. A board with more blue should help get more fems right?

Here's my current setup. I know my seedlings look a little worse for wear but they were just transplanted and should be recovered within a few days.

I'm intrigued by these boards and have never seen them before this thread. They look like an inexpensive way to boost the proper spectrum during each cycle but I don't know that I need to. I'm trying to be preemptive here. Buying two boards is the same price as another 200w 3590 fixture, but a lot of heat could be an issue since they have no cooling mechanisms. With the 3590s I'll get the full 200w during all cycles vs 96w from a single board but I'll lack the ability to adjust from red to blue and vice-versa.

I've seen what you can grow, Toaster, so I do value your opinion, and will take it into heavy consideration. I'm also checking out your grow room link right after this. I will be getting getting a filter and ducted fan system asap so cooling may not be as much of an issue in the near future. I've had a lot of expenses lately that have put a severe crimp in my budget and I've had to piecemeal my whole system.

Hey man!

48x24x60 that's inches right? So 4'x2'. 300W should be enough to covee rhe whole footprint of the tent. Now the question is are those lights actually running at 300W? What are those? Any link to specs?

I've got a 1x1m tent thats 40"x40" so slightly larger footprint than yours and run 315W in there. Those watts are with cooling fans included so I basically have about 300W of light in there. I'm running 9 plants at the moment

So as you can see 300W can grow more then just 2 plants.

Your "problem" is the design of your lights. I've got 6 cobs in there producing pretty nice coverage where you have only 3. Then there are those lenses that narrow down the light beam even more. Cobs normally have 120° angle but those lenses make it more like 90° so you get even less coverage so you need to run your lights higher than desired. At this point you're gonna run out of overhead unless you keep your plants short and evenly spaced out. Might be a pain in the ass for the first time.

You say you're hitting temps in the 90's with those lights. So adding another 200W would put you where? In the 100's? I'm guessimg your tent is somwhere in your place not in the basement or am I wrong? It's gonna be a struggle in the summer when temps rise. Are you exhausting out of the room where your tent is? Are you bringing fres colder air in? Are you running ac in your place or at least in the room where the tent is?

To the best of my understanding these lights are designed by the same people who designed the CXB3590. The diffusers work well at what I'd estimate at around a 160deg angle. They are actually diffusing, not focusing.

I'm glad you asked me the specs because I found I'm running them too close. Need to take them right up to the top and purchase a taller grow tent. I guess I also don't need all three in there either. So I can use the single for seedlings and clones as planned.

I thought the single was a lot dimmer than the double. The double is 185-200w dimmable while the single is actually only 65w and it's set. But now that I know, I'll do something about that. Been looking for a reason to crack one open. Here's the specs...

This is for the double.

Thank you. Like I said, I'm still learning and it looks like I've been cooking them.

Just backed them waaay up. That should do it till I move into my new trailer. The 5th wheel I bought it smaller but has more room. I didn't have space for a taller tent in this one. If I find I don't have enough room in the new 5th wheel, I'll put them on an enclosed porch. As far as cool air, I'll either draw from under the trailer or build a burried geothermal cooler. I don't run air conditioners they're a waste if energy and I'd rather they and I acclimate. I'll make sure they have proper cooling but the weather here has been erratic and I wasn't ready yet.

Those lenses are aspherical, they can't diffuse light, they can only collimate it, and like i suspected, they are 90°

And I don't think those lights have anything to do with Cree but using their cobs. Cree finds using cobs for grow lights obnoxious. However they did put together a reference model, but that was built with 4000K XP-G3 series white chips and XP-E series photo red chips. So I doubt Cree has anything to do with the design of those lights.

I was looking at where light was hitting on the side of the tent, not the specs. They're the ones who said they designed it, not me. (Just checked, their bad English is what made it sound like they designed it. ROFL.) I have to admit, lately I've been having problems with my vision and my mind seems to be filling in the blanks where I can't see. It's been a real pain in the a$$. Scared me a little too because it happened so fast.

Alright, didn't realise you were in a trailer. That makes things even more difficult in summer. That geothermal cooler idea should work a treat and you could put a solar system together for the power to keep it all on the green side. As long as your exhausting warm air from the top of the tent outside of the trailer and bring some cooler fresh air in you shouldn't run into many troubles. Also keep in mind that with high temps your plants are gonna want more humid air, more feedings but keep your feedings lighter.

Get this and forget about that chinese trash

I couldn’t agree more. I got this in the 4000k for veg only and I my plants love it. Want to get 3000k or 2700k to add to my flower tent.

Thanks. I don't know man, I have an autoimmune disease called RSDS and it has some pretty messed up side effects. It could just be that I'm getting older but I think there is something seriously wrong with me and the RSDS is the side effect.

Trying to enjoy life as much as I can before I before I find out I'm on the clock, if I am then I'm really going to go for broke. I want to smoke as much weed and play as much VR as I can. Oh, and there's the BBQs, Patrón, and Pacifico, with friends. I have simple tastes, lol.

I do appreciate your help. I've been struggling with these seedlings since I started them, but now I think they'll be ok.

Toaster, I got my QB board 100w and the cheap cob light I had already purchased (I'm returning) I decided I'd look at it and maybe use it as an extra or something.

The QB is NO JOKE! Holy cow!! This thing is blinding. The cheap cob which is supposed to be 800w is nowhere near the QB in lumen at least. Thank you for turning me on to QB. Im still deciding on main light. A 320w QB with 3000k and 2700k and optics. Or a CMH specifically this one.


https://growershouse.com/solis-tek-c1-315w-cmh-complete-fixture-120-240v

People seem to have crazy good yields with the CMH and claim the UVB helps with quality. I have untill Monday to make up my mind. The 100w QB I will keep as side lighting.

Dude, I am so glad we talked. Since I've lifted the lights my plants are doing so much better. I seriously underestimated the intensity of these rigs. Buying and setting up a new tent is nothing, maybe as much as $100. No biggie. I can finally relax. There were so many problems I've had to address lately, I've been worn very thin.

Those boards this thread is about. What's the distance on them? Can I utilise the 60" grow tent, or is it too short? I'd really like to try them. What's the coverage of the board you linked to? Will I have the best results from switching them for cycles or just keep the 3K in place?

Also, if I pull those lenses should I still maintain a roughly one meter gap, or lower the 3590s. The 200w is also dimmable.

They really are well built units even if the lenses were a bad idea.

Thanks again Toaster.

 

[DrDankPHD]

Not sure what if any difference a cob led would be but the 450w comes with its own timer.. Any suggestions?

Optic one 1 cob. Singles or. Panels work great. The panel got timers.

Cob I like pretty much cree cobs awesome quality. And a driver. Meanwell. Solid stuff.

I got a perpetual going. So I like being able to control the light levels on each plant.

Cob canopy distance is 18".

I got fluence spiderx plus. Distance is like 6" to 12".

My personal opinion is amazon stuff is pretty much shit regarding led. Safety first. U don't want burn your house down.

Cob is way cheaper. The spiderx retails. For like 1500. I got mine for free to test wohoo.

I have since ended up with the 260w XW Quantum board for a 3x3x60 tent. Man this thing is so beautiful. I bought it already assembled and it was the 288v2 board. This thing screams quality! I'll be buying the 600 very very soon. 60" is plenty tall, I keep the light down around 12" and the plant loves it. I have a 64w 4000k QB i use when the seedlings pop for the first week or so, then the 260w. Absolutely love the QB. I got the 315 CMH in my truck ready to ship back, I never ended up opening the box since I was so happy with the QB

 

[MW7945]

My big light I had custom made from the company that made Smithsjunk's light. But I had them use Vero's and not use those awful lenses.

Glad you backed those off some too, was going to say something. Those are still dimmable correct?
