LED Yeild Efficiency?

I'm pretty new to growing, this being only my second, but I went full out committed.
I did a VERY small CFL grow before but I have upgraded (see photo) I'm wondering:
1. Does anyone have any experience with Viparspectra LED Grow Lights?
They can be found on amazon. I would post a link but I don't meet the requirements.
I have the 450w running both veg and bloom 20/4 on a set of kings kush auto fems.
2. I'm wondering if anyone has some input on what might be some yield numbers with LED over CFL. G/watt20170202_214014.jpg
 
More than with CFL of equivalent wattage.
But generic storebought warm white bulbs can already triple cfl yield per watt.

Vipersprectra isn't too great though, but for personal use it should yield more than enough.

That's a hysterically inefficient setup. You do know that, right? What's wrong with a 2' T5 until they get a lil bigger?
 
Sorry u got pulled into the blurple zone. Its a trap many fall into on their search for better grow lights. I did the same thing and wasted more $ than Id like to admit on that crap... Youd be best off selling that light asap on craigslist and building or buying a better light imo.
 
I wouldn't say all blurple lights are crap. Just the really cheap ones.

And as for cfl lights. They've got stuff all effective distance. Hence why you can put them so damn close to plants.

The thing with asking what yields to expect. Coming from a guy who's also on his second grow... Is that it's largely to do with your skill as a grower. What the genetics are capable of. And what light, feed & conditions they get between the time they're planted and harvest.

You can have a plant that's expected to yield upwards of 600g and have everything else in place to get it. But, if you're a new grower. It's more reasonable to expect probably half of that. Until you've got things dialed in.

Take my light for example. It's a blurple cob/led cluster. With a mere 90w draw at the wall. I've been told to not expect anything more than 45g from it until I'm more experienced. Even if the plant under it was capable of doing over 200g. And I kept it happy the whole grow.

The other thing that affects yield is the vegetation time. If you're only growing a couple plants. Longer veg time can actually boost yields.
 
Budsonwheels, don't take offense, OK? You post a couple of innocent questions, then get treated harshly. ttystikk may have been a little bit cruel with his assessment. But people who have spent hours on this forum learning from others, and hours inside their grow rooms learning on their own, then hours back on the forum trying to point newbies toward better choices, can get a little bit frustrated.

To answer your questions:

1) Yes, of course people on this forum have experience with Vipar. If you'd spent a few evenings digging into it you would have found hundreds of threads and thousands of comments re: Vipar. I've read many comments about Vipar so here's my take: they're not the worst blurple panel out there, but why would a person buy one when many of us (including ttystikk) have been trying to steer newbies toward the most effective lights available to us at this point in time.

2) You don't have anything sticking out of the pots yet and you're asking about how many lbs. of bud. It's not your fault. You're curious. But it's kind of annoying. To be fair, your question was a little bit more specific. You asked for a comparison of LED to CFL. That's not quite as unanswerable as when someone gets on here with his little tiny babies and wants to know how many pounds he's gonna harvest.

So I'll try to answer your question, but not with any numbers.

Some LED panels are built with such low-end parts that they're NOT going to grow more bud than CFL's. The cheap panels have:
1) lousy spectrum, so they don't give the plants the colors they want, and
2) low-quality drivers and LEDs, so they waste your electricity, turning most of it to heat instead of light, and
3) They'll probably fail quickly, potentially leaving you in the dark halfway thru a grow. That would suck.

OK, so you don't want the absolute junk. You can buy mid-range stuff like Vipar that'll grow OK but not great. Better than CFL's? Yeah. I can't say how much better.

Or, you can spend your money one time (Timber, GrowMau5, Northern Grow Lights, etc.) and know you're buying the good stuff.

Don't let a few rough comments get to you. People will respect an honest effort from a newbie who doesn't have all the best equipment but still pulled off a successful grow. Because most of us started out with a few half-assed grows ourselves. Then we got better. So keep your chin up, be nice to your plants, and you'll be fine.

Well you did say you were trying to set up efficient lighting. My suggestion was merely to match the light to the current need.

After posting my dissertation, I read your post again and realized you were probably referring to the Vipar running at full screw at this stage of the grow. You even said "why not use T5's" so it was pretty obvious really. Thanks for the clarification.

why is there always a wise-ass who comes here AFTER he bought some shit lights? you ask about stuff before you buy, then you don't need to be pissed about when someone tells you how things are...

I'm not upset about my setup at all. And it is actually a recommended light by high times magazine.

Nothing about how efficient. Just trying to get an understanding of just how much better led will be than throughout a full grow. No numbers. I'm no botanist. So I'm not expecting even 1/2lb off of all 4 plants
 
Yeah they'll be promoting it.! (High times).
Veg with cfls and put your viper on a site and sell it.. That would be more efficient., use cash off sale to buy c.o.b. Lights. You can get them pre-made and there's a few cob light makers/sellers on this site. Or if you're good at diy, you could buy kits and put them together. Good luck happy growing

Exactly. Believe me, I've built myself a reputation for efficiency in cultivation. I'm looking forward to seeing how you grow with yours.

Ttystikk I have seen you all over Rollitup since i joined, I'm researching a low cost led I have $300 at most to spend, what are my options? If any at all? Grow area 40sqf i grow 2 to 6 plants at most20170203_182355.jpg 20170203_182528.jpg 20170203_182355.jpg y

with my best blurble grow i got .61g/w my first grow with cobs was 1.13g/w enough said about g/w. the blurlbe bud did turn out well, but i do have to say the reaction to the white led was better. if you are looking to grow a little personal im sure its fine just be aware you could drop the watts from the wall and grow more and better with different lights.
