Grow light query

QB's are all I run Now, they are FANTASTIC

I DIYd mine, real easy, But maybe not for anyone

if you can get, say a Dual QB288 system, that would be perfect for a 3x3 Tent
I can attest to the dual 288 260 watt QB light.
I have one in my 3X3 and it has been nothing short of fantastic!
Ordering it from the states was easy, fast, and hassle free
 
i did my very first grow in a 4x4 tent (48x48x96) with 1 vipar 600 for the first month and added a 2nd vipar before switch to flower. The umol coverage is decent but if you really want to go for something easy and decent without DIY QB, i recommend the mars 2 1600. Great umol coverage, MORE than enough for 3x3 and u can ensure your plants would love it.

Below: Here's some quick charts i already have uploaded. I used 2 of these for my first 2 grows.


Below: And here is what i upgraded to and am now using for my current 3rd grow.


Hope it helps you decide what route to go. Lighting is definitely very important for your grow. Vipars make great starter lights.

After viewing what is involved in doing a quantum board I think they are the way to go. I do have a friend who is an electrician to check my work. Ledgardener has a video that rocks. I think I would get more bang for my buck. I will keep researching but I'm glad to have choices. Thanks!!

You will love the QBs

Be sure and post what u get

If yer diying it be sure you get the right driver, I learned the hard way, so if yer not sure holler and I can help

It is real easy to build, a few solders, even building an aluminum frame is easy

The kit I was looking at has everything included except ratchet straps. As the video I saw, he explains about tinning the wire leads, and making sure wires are cut to proper length; but if I run into any problems I will be sending you a post. As soon as I get my set up I'll post it. I am having so much probs with my seedlings right now. Don't know if there going to make it. Can't even get them outside. Still getting frosts at night.
 
I have 2 GROWant gr240, great lights and are sponsors. I did two under one start to finish but opted on another for the next grow. $115 each they are a great light. Two would be great in a 3x3 area for sure

How was your footprint with the two GR240s (square footprint, I assume, on those?) in a 3'x3' space? Looks like, in theory, they'd be adequate for nine square feet (or eight, anyway?). But in practice, I'd think that would only really hold true in a rectangular space approximately twice the length as the width (or vice versa). Otherwise, one is trying to cover one large square with two smaller squares. Which... thinking back to my kindergarten geometry class (lol - with colored pieces of construction paper) tells me there'd be a good bit of overlap, significant gaps, or both.

I have a practical reason for asking: When my seeds become seedlings, I'll be doing a grow with a GR480 (pictured, mostly, in my avatar image). Sort of like two GR240s that I cannot separate. And my grow space is around 3'x3' this time. I cannot help but feel that I'll have a bright spot with some shadowing (slightly more on the "short sides" of the light). I might be able to fill in around the perimeter but - IF so - they'll only be low-wattage CFLs.

Or I could dim the 400-watt HPS to 250 watts and run both, extending the width of the grow space a couple(?) feet. But that'll make it more difficult to get an idea of the LED's performance - and I'm trying to minimize electrical consumption as much as I (practically speaking) can. For that matter, I could stick a different LED in there with the GR480, but that'd add 350 watts and strikes me as being comparable to using a Class D semi with 48' trailer to carry the rest of the luggage that won't fit in a car's trunk :rolleyes: - it'd most likely so "overshine" the GR480 that the latter ended up being the supplementary light. Again, this would make it rather difficult for me to get a good picture of the GR480's performance.

Obviously, I could do a grow without the GR480 and still end up with a fair amount of light. However, the sponsor gifted me the GR480 last year when I was having "problems, many & varied" - and he pretty much said that was cool, just send him a link when I was able to start a grow journal with it. This will be my first start-to-finish grow (after last year, I mean), and I'd like to feature the GR480.

I can adjust my space a bit, lengthwise, but the depth (and height) are "hard-coded."

you dont need to tin wire leads if you get solid AWG wire
 
I've seen vipar do good but only with additional QB. so I dunno if it was actually the vipar or not. im not even gonna get started about the other blurple sponsor here... I wish HLG sponsored this site would save some people headache.
you talking about Black diamond Perfect Sun?

I have his perfect sun mini, Im currently using it for side lighting,lol.. another 125 watts dont hurt, thats for sure.
 
I think the leads on the AC side of the Meanwell are braided

yeah, they are, but still, 8awg solid should be used, so better to use a wago junction.

they come tinned already. just need to tin the cord to the wall.

lol no. not that. thats worse than the one I was mentioning. I was talking about the one with the reflector series that you will be dealing with customer service before the year is up. ;)

man, i use 4 luminus cobs, and just use the mini for sidelight.

i also have a PhotonFantom fusion board, but not using it.
 
I built my own light. Was the first time I tried too. I bought led samsung LM301B strips. 96 diodes per strip at 22.00 USD each. Bought 6 of the 2700K and 6 of the 3500K and alternated them on 2 Costco cookie sheets. Bolted the sheets together with some C channel aluminum. Mounted the strips with double sided heat transfer tape. I used two drivers. Since HLG 550 v2 uses a HLG480H-48A driver. I deduced I could use two HLG240H-24A. Reason being. If the driver ever fails I am only down 1/2 my lights. However, I was worried I might have effed up and when things arrived and I wired it up. OMG bright, Very bright. There was always that what if I was wrong in my assumptions. For the wiring, That was easy. I used thermostat wire which is solid core. Not strands. The strips had their own push in terminals and I used wago connectors. I messed up and should have bought 7 connections whereas I bought the two connection ones. Just used shrink tubing and some black tape to fix the connections. It wasn't all that hard to wire. Nice thing about thermostat wiring is once you separate it they are red and white so made red positive wiring and white negative so no crossed wires. Where abouts in Canada are you. Do you have an option for using a company just across the border WELCOME Better to sue them than not. If you ship items to Canada you do have the option to do your own brokerage. google how to do it. UPS is the worst of them all for fees. while USPS is hands down the best fee wise. I have a brand new viparspectra par 600 for sale. It has never been used and I have two of them to choose from. I want 212.99 USD for one or I keep them both. I am going to use one for seed-vegging and the other as a back up. Then my home made light for flowering.
