Hi Guys

I made a slight mistake in my post where I said I was looking at the 135W Blackstar, I actualyl meant the 100w as the 135w won't fit in my case unfortunately. Will the 100w still do the trick?

Sorry for all the questions!

Cheers

EDIT: Here's a link to the one I mean http://www.blackstarled.com/10bl2wch.html

@cosmictraveller - most people would use that for supplemental light, just to fill in dark spots in the grow area the Coverage Area: 1.5' x 1.5' (2 Square Feet) is good for a very small grow area tho

I think any heat issues with the 135W will be lessened getting the 100W and less chance of bleaching though its' leds sit on a reflective panel that newer ones don't have, makes me think it could add heat again... As I said this is the older version of the 135W so I haven't seen many reviews on it. Here's one and acouple prices.

I used their ebay page and had a great transaction with them the 135W is pretty damn cheap on there to, got it for less than the first link, just to back their legit-ness. also they have 99.9% positive feedback. Goodluck on your choosing, soo hard with soo many brands and version ay

Red...how many plants should my LED's do.....?...and what is the record for number of plants under one LED...

I found this link very useful... made a few of my own... works amazing and you can do it custom to what your looking for for like 10-25% of buying one... hope it helps...

forgot the link:

highly recommended for tight budgets... super simple..

Summary:

A 33 watt grow light made from 19 blue and red LEDs. Each LED is glued onto a broiler pan which acts as a heat sync. This light should be excellent for growing many forms of plants and algae. It cost me about $113 in parts and shipping to make this unit. I estimate this light to be equivalent to a 300W HID/HPS grow light.

Special thanks to Green Pine Lane for sharing the original concept of a "cookie sheet" LED grow light.

Hookup:

3 strings of RED LEDs - 5 LEDs per string
1 string of Blue LEDs - 4 LEDs per string
Each LED in a string is connected in series
All strings are connected in parallel through terminal strip
Power:
The LEDs have different power requirements.

Blue = 4V @ 700ma max
Red = 3V @ 700ma max

Power Supply 16.2V

Will not drive LEDs to full capacity.

Blue = (3.5V @ 600mA) = 2.10W = 4 LEDs = 14V (one row)
Red = (2.8V @ 600mA) = 1.68W = 5 LEDs = 14V (three rows)

Resistance - E = I * R

(16.2V - 14V ) = 2.2V

2.6A power supply / 4 = .650A

2.2V = .65A * (R)
R = 3.38ohm
2.2V * .6A = 1.4W
Buy four 2W (or greater) 3.6 ohm resistors (one per row)

Mossy my 6 spot is a little less watt than yours and the most I have had under is 4 x 17.5L pots but if its just to keep plants alive I would hang it high and fill the 1.2 m x 1.2 m floor

So how many could i fit using 3L airpots and how many in 7L? does the pot size mean more pots if there smaller?
