480w I'm using in a 4x4 - for me too low so I've added another 180w (60w x3) of side upper side lighting. The same strips I use on the sides in this grow. Changed them today to on the diagonals - post a picture tomorrow of that tent when lights are back on. Angled them to 45 degrees if that makes sense? Opposing sides. and raised them up a little - so that's 660w in a 4x4! (Yeah and dixie cups Jon! 16oz ones!you're the only one i know who used a 480watt light you used that in a 5x5 right?
Yeah Jon's on the money for me. Totally agree. I want the 1000w in the 5x5 (if it was working!) but we run Co2 from like massive cylinders of it no one - but like really no one should be running Co2 in tent really. Its different for us our tents are outside, we understand it well. Buy mushroom bags you want to do it home, and then only you have no respiratory illness or asthma type stuff. So you don't need our 1000w.I just wanna say GO FOR THAT 700! 480 is way too low for a 5x5 imho. We would all have the same drop offs you describe with 480 over 25 sq ft.
So - and I promise I ain't sponsored by them and probably they aren't my biggest fan! And I ain't saying this because they are a site sponsor. For sure. Site got enough from me!
Me?
I'm buying another @Mars Hydro FC6500 for my other 5x5. Its 730w at the wall and 650w proper. It has a wide footprint. Take me too long to explain in details (though I have in this journal before) but the new FC4800 Evo (so their latest 480w) has smaller footprint than the older, more budget FCE4800's I have two of.
The video up above is 3x FC6500's - they touch sides so close are they! Its fine they run cool and our drivers are detached and wall mounted. They probably cover 120cm each so 4x4 size but we run them close and there we really pump in the Co2 at 1300PPM and a high EC - I'm aiming 1400PPFD 1500PPM Co2 and an EC of 2.8 to 3.0
You need the three together.
For anyone growing for personal, for hobby and fun but with a decent budget ($800?!) n a 5x5 tent its about as perfect light as you can get. But photons are photons (without getting in to a kelvin discussion) - its more the spread and the wattage I like for a 5x5 at around 650w - just buy the safest, best made one you can at that wattage.
Anyone else notice Vipra Spectra and Vivosun top out at 480w? The KS5500 say is actually 480w.
Up to 4x4 home grow or 3x3 its great 480w Why they don't offer light more I reckon. Its not their target above that level.
They'll only really do 3x3 commercial though. There when we add Co2 and run run them as low as 8 inches from canopy its not enough.
A 5x5 like its so much bigger than a 4x4. I know you're like obvious is obvious! But its non linear thing, across area and micro climate. Its a big step up. Think Jon alluded to that with his 25 sqft comment.
Anyway my many, many cents of opinion there!
When I told you guys these were big plants I was serious.
So why'd you post those popcorn colas then?
(Jooooke!)
