Can I add something to my lights for better yield or do I need get new lights?

[Lisa22]

I have 4 year old Viparspectra 300W led grow lights. I have 4 in a 4x4 tent. They seem to do great in veg but I am getting low yields at harvest and think that it must not be enough light in flower. Is there something I can add to help what I have or do I need to totally switch out? Trying to be cost effective with what I already have but know these are older technology. Appreciate ideas!

I'd upgrade to a full spectrum. Blurples aren't good for flower.

What did you end up getting, I remember you asking about the p1500/p1000?

I'm trying to see if I can get a friend in the us to send an xs1500 to me because they don't ship to Canada but if I can't I'm going to get the 135w hlg qb.

Which one/ones would you suggest?

I'm not sure about 4x4 but I'll put a link to a light thread I posted where a lot of knowledgeable people gave their input. It's probably worth the read.

Could my blurple be better than a full spectrum?

I've sort of already talked about this already but I never asked anybody for their opinion on it. So I have a tolys 600w LED from amazon (you can look it up if you want, it doesn't really make a difference). I haven't checked the actual wattage but a review on their 1000w model said it ran at...

Super thank you. Had been searching - so hard to find the right link! Really appreciate.

I just got a Viparspectra P2500 to replace 4 Viparspectra 300's - it shows needing to acclimate the plants for 5 days using 40% light at twice the height. I'm 3 weeks into flower and hate to do that but don't want to burn up my plants. Has anyone else replaced the 300's with the newer lights? Did you go 1/2 strength for a week?

 

[beluga]

Well, you're actually losing more than half your wattage going from those to that. So, you definitely don't need to go half strength.
I would probably keep two of those 300's running alongside the p2500 to get you around the same wattage and you'll be good.

 

[Lisa22]

The one light takes up most of the upper space - no place to put 2 300s - I'll call Viparspectra tomorrow and check.

 

[gorillaglueaaron]

If you can It's better to raise the light rather than dim it because that way you increase coverage while you lower intensity. I'd honestly just put it at a pretty high height/dimmed a lot and work your way closer/brighter and look at the plant often to make sure it's not light burned. Once you find the right height, raise it a bit just to be sure and go off of that height.

Thank you- On their directions they are saying do both. I will call them tomorrow as the directions leave a me with a lot of questions. Will let you know what they say. Excited to maybe put some weight on my buds!

If they're already at 3 weeks into flowering, they're plenty capable of taking an adjustment to light so long as it's the same intensity. Wattage is going to be driving your intensity more so than the type of light that's used, so you should probably be okay with using the full spectrum light as a replacement to the blurple configuration.
Your addition of fuller spectrum light isn't going to impact a mature plant so much that you should be concerned about it being too effected by a light configuration of slightly lesser intensity.
4x 130W (300's) = 520W
1x V2500 = 250W
2x 130 W + 1x 250 W = 510W

As far as space constraints... that's a different story. What size grow area do you have?

I think the p2500 would be more efficient than the blurples so maybe a bit less intensity.

Original Post says 4x4 tent, I agree with @beluga 250W will not be enough for a 4x4 even with those killer Samsung diodes. You will want two of those v2500s to fully replace your blurples.

He’s correct, two p2500’s is what viparspectra recommend for a 4x4, or opt to getting the p4000 (just realized they make this one)

 

[gorillaglueaaron]

The p1500 is just enough for a 2x2 so you'd need the equivalent of a p6000. If you already have a p2500 then you can either get another one and a p1500 or just get a p4000.

You can run a SERIOUS light in a 4x4.

Best Top of The Line LED For 4x4 or 5x5?

Hi Everyone, My wife is letting me get a bigger tent in the garage and I will likely be doing either a 4x4 or 5x5. Up until now my indoor grows have been done in a 2x4 and a 2x2. Got blurple LEDs in one and a little spider farmer LED in the other. I have been able to grow small quality plants...

That's what I was thinking but she's already invested in a p2500.
