New to LED lights

[FramerTim]

Hey GWE I'm new to tent growing and I've been doing my research on what LEDs to put in my 4x4 tent and I wood like to know your opinion on using 2 100w with samsung 301b's or 1 300w with samsung 2935's. On a $300 budget and both are there. Thanks and I love Sunday waking up to Nebula's email😁

I'm afraid you're going to need more than 200 watts of top-tier diodes to flower a 4x4.
I use both lm561c and lm301b diodes in the fixtures I've built, and you really need to shoot for approximately 30 watts/ sq ft of canopy.

How many LED's are you building into the fixture and how large is it?

I built a fixture for 9 50w Vero® Series - multiple spectrum and have been very pleased. Heat sinks on every one with caption tape and thermal compound of coarse... heat sinks where for older Pentium and amd cpus. just be sure to wire them safely and check the circuit with an amp meter to know where you are with power drawl.. I use about 30 -40 $ month in hydro and that includes intake fan, exhaust fan, 9 cup fans and the leds.

I recommend looking at migrow on youtube for his light reviews. I also encourage you to check out the grow light calculator here - https://www.cocoforcannabis.com/grow-light-calculator/ and take a look at the drop down menu of lights they have already done the math and testing for. Likely, the lights you will be choosing from are listed in there.

Need 480w minimum for a 4x4 Sq ft space. . I like the efficiency of the 301b. Hard to beat 220 lm/watt.

I built my HLG550 clone for my 4x4 and saved a ton of cash. I love it. If you need other options for your budget check out LED Grow Lights Depot on YouTube. Lots of great reviews and lists like “Best Passively-Cooled Full Spectrum LED Grow Lights Under $300”.

I just purchased the ViparSpectra XS 1500 and my current grow seems to be lovin it! That light is appropriate for a 2'x2' coverage. For a 4'x4' grow the XS 2020 model is suggested. The XS series uses state of the art Samsung LEDs (including far red) and the Mean Well driver. I'm thoroughly pleased. If you look on Amazon they have a 20% off code good till Christmas.

I think that you will need a stronger light for your space,

I have used the MARS HYDRO 250 for my last two grows, really like it with one minor issue, which is more of my grow space then a problem with the light. Both sides of my grow need to be the same height. Will replace the light sometime this year with two shorter versions of the newer model.


I'm sure there are better lights, but for my approx 2.5X4 foot space it works. 4X4 would hold two if plants were same height

I went with two of the SF 1000 instead of one SF2000, for that reason. I wanted to be able to have a little control over height adjustments incase one side of the tent was tall and the other short. I like the modular approach for dealing with that.
