Constantly changing led light update

Both cfl and led lights availability and prices are constantly changing.

Led lights in particular are well within reach and a very attractive consideration for both supplemental and primary lighting. Grow lights used to be a complicated and expensive way to go

Some quick research on YouTube leaave me to think white, 6500k, light and bulb more than 24w in led and 90w in cfl are required.

 I brought a 65w  6500k "corn" light is that equal to 300w for $20. There are many red/blue blubs too.

Does anyone have any feelings or comments about using these lights?

I've grown stuff hydroponically with expensive lighting and cheaper stuff as well. The plant quality generally goes up the more expensive your lighting setup. Really strong lights produce stronger healthier plants, while weaker light force them to stretch (this is why AG used to recommend CFLs get replaced every 6 months) which makes them weaker.

 

I was partical to using Sunblaster lighting back when I had a lot more room for setup.

 

LED is definately becoming a good bang for buck. The only problem right now seems to be with having companies stay in business for a few years. A lot are fly by night.

I agree, the red/blue, full

I agree, the red/blue, full spectrum lights are better for flowering/fruot plants (at least that is my understanding)

White light seems better suited to lettuce herbs and leafy plants.

I like 6500K CFLs. Haven't

I like 6500K CFLs. Haven't seen 6500K LEDs. Actually, every LED lamp I've bought worked lousy for growing plants. YMMV.

Wattage is a matter of how many, how far, and what you're growing. Too many people look at the problem as one of using a single light, above, because "that's where the sun is". The sun is not, in fact, directly above a plant outdoors. It moves. Just get the bulb within 12" of all the leaves, and use multiple bulbs to do it as needed, and you'll use less wattage.
