Will a 260W quantum board be enough wattage for my 4x4?

[Thickroots777]

hi guys, i am in the process of upgrading my viparspectra blurple to a quantum board, so excited to have a qb in my grow tent but i wanted to make sure that this would be enough wattage for my 4x4 grow tent, i am planning to buy the dimmable 260w respec from niemi led

thank you!

It'll work but you will only be running 16w per sq ft. Ideally you want 40 or more

yeah, you're on the light side... no pun intended
you need another HLG to go along with what you have

I did a 260 watt HLG in a 3X3 and it turned out great

2 of those on a light rail in a 4 by 4 would be a sweet lil setup!

would you really need the light rail?

 

[Marzbadrock]

Is it necessary...absolutely not. It would be beneficial in my mind though. Moving a foot left of center and then a foot right of center would give everything partial full light, eliminating shady spots. Compared to center of tent getting optimal with sides receiving secondary. I believe a light mover would pay for itself the first crop.
I just took a bunch of hlg 288s down, one thing I noticed when using them is they dont have much of a footprint.

LM301B diodes will give you good PPFD when running at 30w/sq ft. You really need a 480w system for that much area.

Oh man, I was thinking about this wrong...long day. I was thinking 2 panels not 2 kits. But no need for light rail running 2 260s.
Are the rspec higher wattage? Or they still 120w per panel?

 

[Marzbadrock]

Sorry guys! Had bit of a brain fart there! Just to clarify my thoughts, 2 of the 260 (4 panels) would rock a 4×4. 1 of the 260's (2 panels) on a light rail would do better than one of the 260 stationary. Sorry for throwing a wrench in the gears!

mine usually at about 135 per panel at max
I usually tone that down a bit
and because I have 3 fixtures, I can really experiment with highs and lows in the tent

You might need the HLG 550 which is around 480w or our Mars TS 3000 (which you can preorder, half price, same efficient) or 2 of the SP -250

We are familiar to the 260w kit you mention. You would need 2 to fit a 4 x 4. That way you get the wattage and par values needed for that footprint.

We sell a similar design and I know our boards can go up to 175 watts. However, we bring it down to preserve the life of the kit.

Ended up ordering the 260w RSPEC from niemiled.com, they were really active on instagram and seem to have a lot of good reviews

 

[Nunyabiz]

In a 4x4 you would need a minimum of two of those.
Whatever it is that can put out at least 800 PPFD as evenly as possible

This for sure.

Good on ya OP for getting the R-spec for sure, but you really need 2 of those for a good return though.

I did 4 plants in a 3X3 with a 260 watt HLG Quantum, with great results
