lighting

A quick warning to anyone looking for Quantum Board kits. I recently ordered two QB kits from the website "growerslights" and have had a pretty crappy experience with them as a company and wanted to share with/warn others. The order was placed on a Saturday, confirmation email was recieved. A...

What's up my LED brothers...... Wondering how many watts per square foot for Autoflower plants? Also 35watts per square foot??? Much love

Hi! I am currently running 2 sensors (inkbirds) for humidity and temp. Now I have a camera inside my grow as well. The issue here is I only have 1 cam and being that it's inside the tent, I cannot see the inkbirds. I don't want to put the sensors in my tent as I am worried about the red lights...

Hello all! SWIM has two flowering tents that are getting finalized for SOG at 2 plants per square foot. One tent is 4.54 ft x 4.54 ft (= approx. 20.5 sq ft total) and the other is 5 ft x 5 ft (= 25 sq ft total). Also each tent has it's own 20 lb CO2 tank with regulator and Saturn controller...

Hey guys, so Im looking into getting some supplemental lighting to add to my set up and had some questions. Im looking at both the Exotic Supplement board and Emerson board from RapidLED. Considering doing a DIY supplement light though as Im not sure the benefits of the IR spectrum that comes...

Looking into making another fixture soon as was wondering if there have been any cool developments in terms of DIY LED lighting. I was on digikey and noticed that the gen 2 bridgelux out which is sweet. apprently higher efficiency. Whats everyone else opinion on best strips to use for a build...

Hello, rollitup! This is my inaugural post. I am a long time cannabis enjoyer, first time grower, and I just wanted to get some opinions from some seasoned growers! A little bit about my grow: I am using a 4x4x80ish tent. I have (2) Mars Hydro 600W lights (newest version, presently at around...

Hi Everyone, I’m a first time indoor grower, up to now I’ve been strictly outdoors. On a tight budget. Grow room: 3ft x 3ft. Thinking of a Roleadro 600W Led Grow Light Full Spectrum. Is 600W enough? Anybody know if that’s an ok choice? It’s low priced, or ist there any other make available...

I'm assuming they have some flex to them? :eyesmoke:

I’m growing 3 plants ...they are bag seed. I wanted to know if using a bunch of cfl bulbs and led bulbs would be good or if there are any cheap led lights with power. Any suggestions? I appreciate any constructive response.

Can someone help me pick out the right driver to do the following. -run 8 x qb 120s -dimmable -ability to top out at 70w per board I am a doofus when it comes to this, so thank you in advance!!!

Hey guys I’m currently growing under a two foot T5 panel and I am really starting to see I need an upgrade. I’ve been looking at hps setups and lately LEDs on Amazon. Even after all the reviews I feel a bit overwhelmed with the choices. I have a 3x4 space 6 tall. I have 300$ to spend on a light...

Hello all, looking into a 4x4 or 5x5 tent to expand my grow and am leaning heavily towards cmh lighting. Have found really nice dual 315w (630w) cmh but for nearly the same price I can bump it up to a 1000w. I guess the question is l, is 1000w going to be too much/will 630w be too little? Thanks...

So this post is to show some of the older heads my set up so I could hear some chirping lol and for the newbies that it doesn't require 300W + to grow. #savemoney See pic. What is your opinion ? :peace::leaf:

I recently changed from blurples to quantum boards, I have 240w (2x 288 boards) in a 4x2 tent giving me 30w per foot. Ive heard this is the figure to aim for! My question is, is there an upwards limit? How much would the yield benefit from pumping it up to 50 or 60 watts per square foot?

Hey guys, I set up a 5x5 for the winter and am trying to decide on LED lighting. Right now I'm planning on going with two King LED 1500's. I already set up my ventilation with active air 400cfm so heat isn't an issue. Any suggestions are greatly appreciated! Thanks

I think I've eliminated the hair-pulling "dim" spot that I and have read many others experience with their Adjust a Wings. I've only been using a pretty inexpensive LUX meter, HOWEVER, that is my control variable. Anyway, I've always noticed it spikes on the outer wing edges to 1000+ on my...

What would you guys say is the most important part of growing that determines yield. Speaking both quantity and quality. I've been told that the amount you yield can vary between 1 gram for every 0.5-1 watt of energy used in lighting, determining in skill, and as far as quality goes, that's...

Hello! All my supplies are almost gathered for my next grow. This question is about choice of light for just starting out. I ordered a 2' 4 bulb T5 HO fixture with 6500k bulbs. It states lumens per bulb is 2000, and claim that gives me 8,000 total lumens. Idk about that, do lumens add per bulb...

If this has been talked about in previous threads, I'm sorry for the reoccurrence, I'm building out my room for flower and I've come to a standstill with choosing the correct light for my build. my space is a 18' x 16' sealed/insulted room with an a/c unit and dehu to control the environment as...
