Led Growing Is The Way Of The Future My Friends

lol, i'm not butt hurt at all, i'm good to go with my knowledge and grow. but it bugs me when folks without real world knowledge on a subject inject hypotheticals (of course, this is RIU, so it's expected i guess) and then slam those trying to advise what is going on in 'their' space. please explain how my room isn't sealed and provides excellent passive ventilation. you have several real world users telling about their experiences and you still feel the need to dispute them.

Don't bother going into that much detail, he just doesn't "get it".
He may get it but people can get pretty dug into there methods and it's easy to be defensive so I just threw it out there. In my case I cut down HID temps and watts when I switched over to induction lamps and hope to further benefit overall flowering by reducing pytochrome switching time with using low wattage, <10 watts per panel, monochromatic 725nm LED's that run only 10-15 min once the plants hit 'lights out'. This is a relaxation technique that research I've read shows promise. If anyone here has had any experience with this I'm all ears.

Not our butts just our heads :) Finally something Harrekin and I agree on :) I went with blackstars based on price vs performance as well (only way to get the wattage I'm wanting without 2-3x the cost from other manufacturers) - I'm happy with mine so far but still another 3-4 weeks before harvest :)

I'm not really seeing any differences in this grow so far vs a 600w HPS, but I know the real tell is going to be at harvest. This plant so far is as big as any other I've ever grown under a 600w at 5 weeks in, and she was a late bloomer (didn't show full flowers til over 2 weeks in) -- I really don't see how based on the current rate of growth, which should increase in the final weeks, I'm not going to yield 2-4oz off this plant. That seems pretty good to me for a plant that was put into flower after not much more than a month from seed (probably around 6 weeks). She was even a bit stunted in early veg due to a ph/heat issue.

Is that your only plant? It'll be interesting to see how much it thickens up over the next 2-3 weeks tho.

looks sexy! how you like those Super root air pots or whatever there called.. i was gonna snatch some. use them for flowering. are they a bitch to transplant with?

Nah I have other plants I just figured I'd show my oldest/farthest along - lots of other pics in my grow thread.

As far as the airpots, they are easy as hell to transplant from since you just open up the pot and take the plant out. The pain point with them is watering, which needs to be eased into or you'll get water coming out the side holes.

Actually someone did a comparison between led's and mh & hps...identical grow rooms...identical plants...same light schedule...same nutes...EVERYTHING totally identical...there was no appreciable difference in plant size...quality or yeild...the big difference was cost of electricity for the mh and the hps versus the led's, and of course the price of the led grow lights
link with pictures or it is bs...

theres a video on penetrators website...

it shows the 200watt penetrator vs 400hps. youtube video and everything.. HPS wins. hps is 34grams. led was 29.. hps pulled 439watts form wall. led was 205. LED bud looked x3 triched up. also for half the wattage draw ill take 29 to 34 ALL DAY.

Really nice Beef!! Here are my current all LED buds (4 x Blackstar 240w) :)

Day 17 from last night - White Russian and OG Kush

Medicine Man - late 20 days (not sure due to great RIU crash of '012)

Some more advanced OG Kush buds (also unknown date due to RIU crash - I am guessing these would have been around 30-32 days in -- this plant has been stunted its whole life and has very few fan leaves left so it's hard to say. She's had a hard life due to being probably the most finicky plant I've ever grown. Luckily her sister has been less problematic.

The trick to that is to compress the soil slightly when filling the pot, make sure the two lines of filled in cones are at the top (i.e. the yellow bottom of the pot should be attached above the row of large inward cones 3rd line from the bottom). The filled in cones act as a reservoir if you fill the pot enough and tightly, they'll have plenty of air from the holes so you can afford to pack it tighter than a normal pot.

Also its absoloutly key when watering to break up the surface of the soil, and not to have let it dry out too much, cos it's much harder to rehydrate.

Doing some airpots from seed like the ability to see the root growth but the other airpots made of material seem to grow better, at least this time, but you are right on about the watering.

For the second time in a week find myself agreeing with Harrekin :) Breaking up the topsoil is essential for proper watering on airpots. Huge difference.

HID'S Rock, LED'S Rock...Mix both and win...save electricity, tweak spectrums, manage heat. HID solves LED's footprint problem, and LED tighted HID's hefty wattage belt and wastes less Watts on non PAR wavelengths. You don't need super duper LED's, just not crappy ones. Especially if you mix the two.

I have had success (especially as a total newb) with this mixture.
and yes, the quality is different, especially if you have the correct spectra in your LED.

Flower with a 7200K MH and tell me it didn't fuck the shit out of a 2700K HPS quality wise...small wavelength light is a big factor...I have done both across several grows. HPS produced more, MH produced better...Must be genetics? I don't think thats the whole story
ML produces more UVB light which increases THC production. Check Ed Rosenthal's Marijuana Growers Handbook. Page 116. However HPS is still better in several ways compared to MH. It is best to use HPS up until the last two weeks then switch to MH. My dad has done this for years because when we tested it the results were obvious.

are these decent LEDs to compliment a 400w HPS or act as a mother keeper?

http://www.ebay.com/itm/2x-168-LED-Grow-Light-Blue-Red-Bud-Spotlight-Par38-Free-Socket-Hydroponic-Lamp-/370562683434?pt=LH_DefaultDomain_0&hash=item564741d22a::

lemme know what u think so i dont make a mistake seems like a good price u get 2 of them for $50??
those will not come close to a 400w hps , growing with leds is mostly done with stand alone panels not screw in bulb style leds like that , i would stay far away from those my friend. check out viparled or blackstar or GLH they all have nice panels in different price ranges alot more than 50$ i might add but when you factor in the fact you dont have to buy ballasts for these units nor do you have to run A/C or have a bunch of inline fans to cool your hoods after all that leds dont seem so expensive to me at all.

i wasnt comparing it i was saying to compliment which mean run both at same time..i thought they where garbage lol didnt hurt to ask! thanks
