This is a sticky topic.

I just threw it in to analyze but here it is next to the quantum board as is. It's super hot in the box.

Exactly my plan. That old type of panel cools better out of the box too. So I can reduce the fans by simply improving the air flow
-
Since your an electrotech any way for you to rearrange the panels more like a bar light? You'll get better light spread if you can.

Rootsruler there you go. Friend quit growing. All free. 300w old school light. 4 inch fan with humidity controller unit. Timers etc lol. Problem solved. Thanks Cory. 😊

FYI. my friend just gave me this old style 300w. I'm an electronic technician so I'll disassemble it to 6 panels and ditch the box. Add a dimmer and better cooling. That'll work. And I like the free price.

I get it on the brand name vs value lights. My phlizon lights have worked fine. Thanks for the calculation. That's helpful.

I would start with figuring out what wattage would be appropriate to take my plants to harvest. The general rule is between 35 - 55 watts per square foot. You have a 2 x 4 so you have 8 sq/ft. 8 x 35 = 280w minimum/ 8 x 55 = 440w maximum.
Any light within those parameters should fulfill your power needs. Most grow lights fall within acceptable light spectrums so I wouldn't be too picky about what brand and focus on build quality and reliability.
Personally, I've used Bestva lights through most of my indoor growing having tried out most of the popular brands like Mars, Spider Farmer, HLG, etc. and not seeing any bump in dry weight production from using those lights. I've also experienced a high rate of reliability with Bestva lights. I still have one of their original Blurple lights from around 10 years ago. All diodes and exhaust fans are working. Build quality is also acceptable but I have seen others with better like from Gavita but certainly acceptable for the home grower.
My opinion would be to go with BAT-W400 from Bestva. 400w bar light. If you're in the continental US you can get it for $289.90. That comes out to .73 per watt. I haven't found another grow light that is that economical and perform the way it does. It's not the fanciest but it gets the job done without a hiccup.

BTW, I am a fire alarm and low volt tech. I could assemble my own parts but I wouldn't know what to use. Plus labor etc

Always watch the sales. Clone machine $100. Clonex, last bottle $37 lol

Right on Bluey I am looking at reasonable bar lights. And ya if you track the prices you can score. I don't mind having overhead on the drivers to keep heat down.Last edited by FurnaceBoi; 08-01-2024, 09:41 PM.

I too am using a 200w quantum board in a 4x2 space, but it's only for veg.
If I wanted to use it for flower I'd be using a bar light minimum wattage of 240w and shaped like the space.
So Mars Hydro FC4000 320w or Spider Farmer SE4500/G4500
Both a bit of overkill and there are other solutions but those are probably easiest, and when on sale quite cheap.
Wait for the sales if you can

Simple question. I have collected a nice bunch of gear to make my small 2x4 grow be very productive.
Well, now I would like to upgrade my lighting in my flower tent.
I'm using a 200w quantum board now. Very interested in any suggestions that would give the full 2x4 coverage.
I am on disability so I don't have an unlimited budget. I do know you get what you pay for too, so not afraid of the investment.
I would love to move the quantum board to my new 2x4 propagation room so I can set up a 2 week sog.Last edited by FurnaceBoi; 08-01-2024, 09:25 PM.

Coco tends to pH on the acidic side. I would stick with soil if you're looking for media buffers.
