okay awesome thank you I will prob end up getting that setup! now to make it budget friendly is it possible to buy the three boards separate, the driver and the heat sink or is just better to just get the kit from them??

Depending on what price you find the individual parts for, you could save 50 dollars or a little more.
If you do end up going the HLG route, remember the 10% off code RIU10 (DIY10 works as well) that @PadawanWarrior mentioned.

Wouldn't that be a little much for a 2 x 4?

It says for veg 5x5 and for flower 2x4 is good on the website... As this is my first setup would it be okay to have this light as just the only light? I only have room for like one tent I would say

No, It's about perfect. He doesn't have to max it out.

If HLG says they work id go with their recommendation. How tall is the space you are gonna grow in?

by maxing out you mean I should prob dim it in veg and then in flower boost it correct? sorry I am very new to all of this!

Yeah for veg dimming would be needed.

the tent im looking at is 2x4x5 so 5 in the height department I am planning on doing like 1-3 plants for a first grow to make sure I can manage it all!

Go with something taller, you will need the overhead unless you plan on doing a very short veg cycle and going into flower early. Pretty sure others will say the same thing.

Exactly. Or you can leave them turned up and just keep them higher. Then the plants will acclimate to the more intense light as they grow up to it. That's what I do a lot.

Yeah, 4X2X5 I think is the maximum tent size I can do for my area... For veg cycles I would prob have to go short would that be problematic would it be better to do a different dimension setup for my space??

2 x 4 x 7 or 8 feet would be a better bet but with aggressive training it could work out. Personaly I'd got with something taller, plants and fans, pots and everything fills in space really quick

Here's what my veg tent looks like with 2 135's at like 80-90 watts a piece. It's only 5 ft tall too.

okay okay I see I think I will just have to just dive in and learn as I go then! I will be asking tons of questions once I am setup with better equipment right now I got like a space bucket kinda thing! So I will be back soon with better stuff and more questions soon! thank you all for all the recommendations and help!

Hey man I meant to pass this link on to you. Scroll down and you'll see a PPFD map for the HLG 320 watt kit. It doesn't say R-Spec so it's likely that the tested light was the previously
released V2 model (with LM301B diodes and no Osram Oslon SSL 660nm diodes).
Keep in mind that the 320 watt kit testing was done in open air and the Indoor Frost light testing was done in a tent.

So what’s the difference in terms of open air vs tent and then par readings from the b’s vs the new h’s??Hey man I meant to pass this link on to you. Scroll down and you'll see a PPFD map for the HLG 320 watt kit. It doesn't say R-Spec so it's likely that the tested light was the previously

The tent has reflective sides so the average PPFD will be higher. A majority of the photons that don't initially hit the plant canopy will strike the reflective surface and move back towards the plants. As opposed to open air, where any stray photons not initially directed to the canopy may end up lost to the plants. This is somewhat less of an issue with LEDs than some other types of lighting because they are made to a specified beam angle (e.g. 120 degrees).
The IndoorFrost Pro (LM301H ) and Eco (LM301B) both utilize a Mean Well ELGC-300 driver but the Pro model does use 424 more diodes. I don't see mentioned what flux and voltage bins were used for the diodes on the two lights. Anyway more diodes driven softer will raise the efficacy level and PPF output, 2.8 µmol/J vs. 2.5 µmol/J and 780 µmol/s vs. 700 µmol/s as stated by Indoor Frost. With the higher PPF output and the same size test area (4' x 4' grow tent) will come a higher average PPFD. In this space that figure is 40 to 50 µmol/m²/s higher, depending on the hanging height of the light.
