Is this normal size for 9 week veg of Indica?

Yeah they look small for 9 weeks but they look like they've been pruned back

 

Your lighting is insufficient for 4 plants. A 600w viparspectra actually only draws about 260w.

If you were hoping for 4 oz per plant - 1lb, you’re going to be disappointed as you would need to do more than 1.5 gpw which is not going to happen at the height you would need to keep that light to cover all 4 plants. The light should be about 10-14 inches above the plants during flowering ideally which just isn’t going to happen to cover all 4.

2.5 oz x 5 plants under a 260w viparspectra... wet maybe., highly doubtful dry.

Don’t fall for it. All blurple leds mislead on their efficiency. So many people fall for it too. The “600w” is the maximum that the chips could do. They’re actually only drawing ~260w.

I tell you these things out of personal experience. I’ve flowered a plant under a 300w viparspectra. I know their limitations (many people on this site will tel you the same thing btw).

Do yourself a favour and just use your 600w hps to finish the grow and you won’t be disappointed.

There's nothing wrong with that light but everything in that statement of theirs is absolute nonsense

 

This picture says it all - even in their description it says 260w actual and flowering coverage 2.5’X2.5’ and that’s at 22” above canopy which is way higher than it should optimally be.

This is at 28 days of veg. She is Critical Purple

 

Yeah. The viparspectras Aren’t going to get ya that in a 4x4 but that 600watt HPS would come close. If you’re wanting HPS yield with LEDs take a look at the HLG quantum boards.

Get quantum boards you wont regret it

 

I absolutely think you will hit that mark my friend, all day, even if they jump low like 10% in Flo, with vegetative structure like that your are gold balls! Every strain is going to be different depending on who, what, and how it's grown. So are you right for 9 weeks? I say Yea as long as you think you are!! But one thing is certain Veg is the actual foundation of the house, and Flo is the drywall and counter tops! You sir have nothing to fear if the big bad wolf starts blowing at your door!

You did see he’s using a 260w blurple led and thinking he’ll yield a pound right...


My New Grow

 

It's possible! He has the right structure, given proper training, it's possible, it may not be the best, it may not look like a runway model, but he has nine weeks of Veg, that's alot of vascular structure, and even if it was impossible, sitting here hypothetically debating its possibility is not productive to anybodies grow room, and could be potentially detrimental to new growers because without skyward dreams we never reach the sky! You all feel me?

1.5+ gpw from a blurple led positioned too high above the plants to cover an area that it’s not meant to cover is not a realistic expectation no matter how you look at it. It’s nice to dream big but it’s better to be realistic.


My New Grow

 

I love where they say "compares to a 600w HPS / covers 2.5'x2.5' "
Haha

.....
As for yeilds, most growers wouldn't get half a pound from that wattage. A pound from that light is not a reasonable goal for a seasoned grower, let alone a beginner

 

Now that I read back through it again, you are probably right! He did 10 out of 5 with one 600, but I would still really like to see this play out!

Edit: OMG I am so stupid, I thought that we were talking about HPS this whole time cause I am old and out of touch. Sorry won't post late anymore!

if you exchange the LED for your 600 HPS it would be possible. i have 2 x 600hps & 1 x 400hps and i pull about 2.5lb to 3 lb avg with 35 day veg & 9 wk flower.
