LED for two

[curley wurley]

Hi,
Finally trying my hand at growing with LED lights...wasn't getting the results I wanted with florescent lights.
(actually I was doing sunlight during the day and florescent at night)
Wanting to grow two plants, on a budget, so my questions are:
How many Watts will work?
Can you recommend anything?

Thanks for any help...

Depends on what type of LED. If blurple colored go with 45-50 ACTUAL watts per square foot for maximum yields. High quality COBs or quantum LED boards go with 35-40 watts per square foot.

Ahh...so for example a panel lamp with 1000 watts could be overkill?
And I should be thinking more on the lines of 400 watts?

What size is your grow area?

Spare bedroom...so I can go up to 6 x 6 if need be.

Well, if you go 6x6 that's 36 square feet so if blurple led go with 45-50w per sqft. 1600+ actual watts. 5x5 go with 1100+ actual watts. 4x4= 720 actual watts.
Just look at specs closely. An advertised 1000w led grow light may have an actual power consumption of 200 watts. Go by actual, not advertised.

Is it safe to say "bigger is better"?
Was thinking 4 x 4 would be sufficient...but I was guessing 600 watts
would work. I guess not now?

 

[fanleaf]

In a 4x4 600 actual watts will grow fine but not to full yield potential etc. 700-750 would be better.

Understandable and thank you for the explanation.
( I wasn't a math major...lol)
Now the search begins !!!
Thx again fanleaf...

Hi Curley, usually for led grow lights, you will need 30~40w/sft for veg, and 35~50w/sft for flowering. So for your 6x6 aea, you will need at least 1000w for veg and 1300w for flower. That is for normal blurple led grow lights, and now we have an upgraded ones : Mars Hydro TS, and Mars Hydro SP, will save 30% more energy , if you grow with these lights, you only need to use 700w for veg and 850w for flower. Saving a lot energy.

Why it is more efficiency.
- Traditional blurple light only put PPE around 1.8 umol/j, but these two lights put out around 2.15~2.4umol/j . Much more light efficiency.
- New SMD tech, light more brighter and use less power.
