i already have CFLs but i've had those for a while, and i hadn't even heard of growing with LEDs prior to buying the CFLs. Do you think, would it be worth it to switch from CFL to LED for the veg state? Anyone have the average grow rate of growing with LED recorded? i want what ever contributes more to a bigger harvest.

Seriously your switching to the wrong thing.
So many have tried alternatives but the serious ones return to HPS. Wonder why?
There's a few threads about here you should read, with a touch of salt!
Just because it's written doesn't mean it's rite.
I find it's about how well you want your plant to grow or if it's an experiment.
Good luck on whatever way you go.

are you saying use HPS for the whole grow?
i currently have 1020w CFL for veg with a 400w HPS above that for flowering, but nothing growing right now

I tried the lot and get the same results with HPS all the way.
It has enough blue spectrum in my opinion.

I have to agree with feral here although I have seen a couple rather impressive examples of both cfl and led growing in this forum. IMO if its bigger flowers and bulk weight that u want, then u cant go past HID lighting.

Until LED units have the price range of CFLs, go CFL.


In the matter of Bigger fatter buds, HPS all the way.

MH/HPS seem to be the lights to go for bigger fatter and mass production of bud. But what about quality?

I have a small grow space, 4'x4' I really dont have the extra money to dish out right now for MH/HPS. So I guess my question is, should i just go with the cfl? If so how many would you say? Or should i just hold of germination until i can afford mh/hps?

Gardeners have been averaging 1 gram per watt with our lights on their first grows with them. This ranges from newbie gardeners to some with experience, but most seem to be right at the 1 gram per watt rating at their first harvest. Many achieve much higher than that on round 2 and 3. One individual currently growing with a single 126W is looking to break the 2 gram per watt barrier with our light within the next few weeks. From the looks of his grow, I think he will. When considering LED's, you usually get what you pay for (except from those companies who just jack up their pricing to make you think it's better). Our products are proven, and you can see independent results by clicking the link in my signature. HID doesn't even compare side by side with our product, even with twice the power.

LMAO, you take the one grow that wasn't done from clone to harvest? The grow where he put two larger plants under HID, and they both barely out yielded the LED even with over 60% more watts? You've gotta be kidding right?

Now go to the link for that grow that you used as an example, and go all the way to the end. Notice that the grower is doing the test over from clone all the way through bloom, and just like the other 2 individuals (Opt1C and BlazeOneUp) our 205W LED is outperforming his 400W HID. The plants under LED will enter bloom larger, and with more nodes, and once the test is over no one is going to be wanting to mess with HID again. Too much heat, too much stress, too much power, not enough yield. So yeah, when you take 3 EVEN tests from start to finish, you see that in each of them our LED is outperforming HID with over 60% less watts. Sorry HID lovers, it is what it is and these tests are done by independents just like you. Our LED technology is already able to replace HID, and my thoughts are that HID owners should be happy that something better is finally available.

Its all well and good but the fact is nobody is going to switch to something they don't know, and most are less likely to try it out because of the price tag. Why pay 250 for what 100 watt equivalent when you can pay 250 for a 1000 watt thats been proven for years that it works? Once prices come down im sure more will be willing to try it, but til then i'm sure your orders are slow.

I go from start to finish with a 600 hps w/digital ballast,no problems,get the whole kit for 200.00.I've seen LEDS next to hps,and the plants always reach for the hps,that tells me one thing.

Contrary to the wishes of people like yourself, orders are not slow, and LARGE orders are getting placed with even greater frequency now that there are more HID vs LED examples with our lights. People getting 10 or more of our 345W lights is becoming common, so there aren't as many people as you'd think who are concerned with the price when they see what they get for it. Most people understand that electricity costs money, and that paying for buttloads of it month after month to do what you could do with LED using over 60% less power, simply doesn't make any sense to today's "green" gardener. Not to mention those $100 bulbs you have to throw away every year. So even though initial costs may be higher, in the end it saves you over double the cost difference of the HID. People have simply been waiting for LED to outperform HID. Now that it has, they aren't waiting on the fence anymore to make a purchase.

Yeah, it tells me they were using one of our competitor's LED's. 420 Magazine did a test with our 126W light against a 186W LED panel from Haight Solid State, and our panel produced 2.4X more yield while consuming 35% less watts. We put our 205W light on a Quantum Light Meter and it put out over 2900 micromoles at 2" away from the sensor, whereas the 250W Lumigrow light with their 5W LED's put out just under 1000 micromoles at 2" away.

We also tested a 600W Metal Halide, which put out just over 1200 micromoles at 6" from the glass. Our 205W puts out over 1470 micromoles at that same distance. Perhaps in the past (or with someone else's product) you'd see the 600W HPS drawing the attention of the plants, but that will absolutely not be the case with our light. We have a 345W vs 600W HPS test being performed by a hydro store beginning soon. Should be fun.
