could i use this LED from start to finish

[littlegrow]

Hey guys so im wanting to start growing with LEDs but i was wondering would this cree LED 30 watt be okay for growing ? or is it better buying a few 3watt in the right light spectrums ?

You still want blue light for veg and red light for flower, usually big LED systems are 200 to 300w and full spectrum with red and blue LEDs, you would need a ton of those bulbs and need to find the right spectrums if you went that route. Apollo has cheap LED systems if youre looking to go the LED route for reals.

it has red and blue i want to do a small micro grow using LEDs you see like a test run

Emitted Color: Blue+Red (8pcs Blue Leds + 2pcs Red Leds)
Wavelength: Red: 620nm-630nm, Blue: 465nm-485nm

Too many blue and not enough red. For growing with just LED your going to need more than just two colors. I'd go with a mix of 5 with royal blue, blue,6400k white, red, far red for a full LED grow. These would make an excellent supplementary to a HPS.

Yeah that bulb will certainly do a lot better for vegging than flowering, maybe supplement with a full red low watt ufo style led?

Actual wattage after adding the driver will be more like 20w

Here in US Lowes/HD sell household screw bulb PAR flood lights ~ 30w. Combine with a cheap 2-3 bulb Vanity fixture and you're golden for vegging

IME, < 100w is not going to provide dense nuggz, especially when those watts are < 80 lumens/w

Now, those numbers have no real meaning to plants, but thy are an indication of what to expect

The number our plants care about is umoles/m^/sec, which costs $$$$ per square meter

Here's an incredible thread on LED lighting that should cover just about everything you need to know - Slips explains leds.

I agree w/ Drgr33nuk, the spectrum for both the LED on ebay and your plan are far too blue-heavy. FreedomGrower has a good graph in the thread I just linked to, that might convince you that blue lighting, even in veg, isn't entirely necessary. Cool-white diodes have plenty of blue to veg, and you'll see that a good number of newer LED assemblies come with them.

This is mostly true, but potentially misleading. It's true that lumens are a measure of brightness as humans perceive it, and that lumens/sq.ft (lux) doesn't really describe how effective a bulb might be growing. The umoles deal is called photon flux, and you can think of it as "PAR lux," in a way. But this still doesn't paint a full picture, because plants don't use PAR evenly across all 300nm.

I can't recommend FreedomGrower's thread enough if you're serious about growing with LEDs. We haven't even started talking about the optics on LEDs, which should completely change the way you think about light intensity and penetration...

i personally have never tried that light and to be honest i wouldn't recommend it. light is one of the main necessities to grow. i have several led panels. from 1 afo 90watt, x2 triband 120watt , 1 pro grow 180. i think the pro grow 180 pulls 120 watts or 140 watts dont remember. 3 watt diodes or bigger are a necessity for good plants. my ufo can veg and flower one little plant but its weak sauce. i dont even use it. the 120 tri bands i use as a veg light and a side light for flower. pro grow is my main flower light. you could pull 2 to 4 oz off the progrow 180 if wanted. i got a little over 1.5 oz once off one smaller amnesia plant under the pg180. i would like to try the pg with the intensifying lenses though.

i have a very small grow once in a while and the pg180 is more then enough from start to finish and has selective switches if your into that.

@ littlegrow -

You want a high wattage, even with LED!! When LED panels first made the scene, I was duped buying a low wattage panel....miserably disappointed!!

Save up your Є / £ and buy something that will last for years!! I have several...450 and 2 600w LED. Pleased as punch! Have a 200 w UFO for sequestering prime looking males for pollen collecting.

Small area, look for at least 200-250 w.

8pcs Blue Leds + 2pcs Red Leds？This will lead to plant a little flower.

I think it should be 8pcs red leds+ 1or2pcs blue leds.

Personal opinion, for reference only.

hey Ari thanks the auto looks alot better.. Flushed it a couple of times. Noticed alittle bit of burning until recently. Ph is around 6.5. No burn on newly developed leafs. How long should an Ak auto take from seed to completion? Seems to be longer than I thought it would be. Is it because of the recent burning?

I think its way to weak. You're better off with fluorescent light.
