theres that typical talk about leds i was hopin to avoid. im doin led right now and it gives some MAGICAL results. they grow like u wouldnt believe. yes a MH is slightly more expensive to buy, and expensive to operate. more so than an led. ive got two 24 W cfls for supplementation just because we found an aerogarden that made us not need the 2 cfls we had...so we threw em in. if anything im seeing they dont make ANY excess stretch that MH will. You can also get it an inch from the top of the canopy with no heat stress AT ALL. all pros with this led. its quiet, cool, effective, and cost efficient. LED>>>>>>>>>>>>>>>>>>MH

Here's my thought process...I don't need an HPS for germination or veg. I NEED one for flowering. To buy a whole new hps or mh lamp just for veg would be crazy. Thats another $250-300. So an LED for veg is the smartest choice by far. Its cheaper than the whole hps/mh set up, not as hot, not as energy bill expensive, not as bulky, etc. Has anyone or does anyone plan to use an LED for their veg cycle? Even more specifically, a blue ufo led? I'd love to know anything about it you wish to tell me...other than how they don't work, are too expensive, blah blah blah. I plan to be using a blue ufo 90w led for veg within the month. Lets get this straightened out!bongsmilie:joint::eyesmoke:bongsmilie:joint::eyesmoke:bongsmilie:joint::eyesmoke:

I love LED for supplement light but still use one cfl for the light and heat. HPS for flower.

everything I have tried other than HPS has led to less dense product. Some strains have been bad enough they weren't worth the nutes.

That said I have only used LED grow bulbs that are very directional, but bright in that direction. 80% of it is red light. Rest blue. I have loved these things for sprouts. IMO a bulb per sprout. Then once the girl is big enough to go beyond the led beam with it a few inches away, I add a cfl till flower. Sometimes if I am not using the LEDs I clamp them in flower room and put them close to new tops as supplement. From what my light meter says, it would be hella expensive to get enough LED light for me to even consider it for flower. I wish they did produce for me, I like them.

I have to add to this discussion I bought a 90w ufo from ebay and it doesnt seem to do much unles u put it an inch away (penatration my ass) , but i have been using warm led downlights to supliment and it seems to make em real perky all the light is directed in a tight beam where you want it i think there 4500k the warm white and i have somereally blue ones but can't figure out wich ones to use more , but I recon in da middle of summer ona hot rroom thesse led's will shit on a hid lamp (too much heat ) i found those 10w bayonette or screw in led's dont have any focusing thingy but the downlight do just need to fit them sumhow peace.

yeah they should probably bust out a bunch of 5w LED's in panels instead of the regular 1w or less ones... I completely agree with you though MH, HPS etc is the way to go for now, Just thought hey I might as well give it a go and see what happens, might get lucky if the lights concentrated enough on certain areas, might end up with fuck all smoke and it'll be lesson learned :)

Anyone who trashes LED's, has not used them, or learned how to use them properly. They are fantastic for veg, and your plan to use them for veg, then supplement them with your existing lights is perfect, keep the LED's on them for 2-3 weeks after flip to 12/12, once they slow down/stop the stretch, supplement them, maybe use them as side-lighting, you'll be impressed with what they can do. I'm on my second grow w/LED only and I'm not seeing any downside, quiet, no heat, low hydro bill. Nor is my son, who's switching to LED's next round after seeing what I've been able to do with them, he's been growing with HPS/HID for years. Don't listen to bullshit on here from growers who obviously have no experience with them. And I'd say it would be difficult to find LED panels using 1W (which I'd agree would be crap) these days, most are 3W and many are now 5W, they work just fine and rock for vegging.

Im growing purple haze and northern lights. I used a 120w led for veg, a 600w hps for flowering. I am considering returning to the 120w led for the last 2 weeks whilst dropping light from 12hrs to 10, to stimulate fall, purely experimental. Has any body done such an experiment?
