300w LED + Alien Blackberry grow

Kill a Watt · Feb 5, 2013

What up. Been lurking around the led threads and finally decided to do a grow thread with my new LED. I’ve been on the fence for a while and decided to take the leap after seeing some success with other peoples grow. After doing much research, I decided to get some quality parts instead of ordering the ones made in china. The Chinese fixtures are cheaper initially but who knows what is under the hood? Could be a sweet ferrari body with a kia engine lol. Anywho, on with the show. I decided to go with a shorter strain and chose the Alien Blackberry for that purpose. It finishes anywhere between 2.5-4’. Soil will be the grow medium. I’m curious how much yield will result from this light.

-This is a legal prop 215 grow-

This is what I will be working with
· 1” thick foam walls with reflective material

(originally was going with a tent but concerns with heat retention made me reconsider)
· 15 Alien Blackberry clones
· Soil
· 1 or 2 gallon pots
· 300w custom LED from LEDSUPPLY.com
*Carbon scrubber & fan will be added before the flip*e edges.

Lets start with the ladies. Some are already much taller than others and that might play into shading so Im going to set the taller ones on the edges.

Here is the LED fixture. I forgot to put on some shades when I turned it on – super bright.

It fluctuates between 309w and 311w

Building this was a true learning experience. Thankfully ledsupply had some great techs that helped me through the build. I took some photos and made instructions.

I went with a 3' makersled heatsink from ledsupply.com

Tools, Equipment and resources needed to get the job done

Solder Iron & Solder

10mm Wrench
Wiring Schematic
FlexBlock Data Sheet (Boost-Only Mode Wiring Diagram)
Red, Black & Blue Sharpie Markers

Here are some general step by step of what I did to build it. I might have missed a step but pretty sure I covered everything.

Organize Materials

– Double-check all part#'s & quantities
Add Solder to ALL solder pads on EVERY LED
DOT LED location on heatsink w/ appropriate color sharpie markers
See LED Schematic
Measure, Mark & Divide the heatsink into equal 3rds (DOT 1-foot at a time)
“Approximately” (start 1” in from end and space DOTs 2-inches apart)

Kill a Watt · Feb 5, 2013

Apply Epoxy & Place LEDs

Set-up correct pattern of LEDs before applying epoxy
Mix appropriate amount of Epoxy (5-minute cure time) – Shoot for 8-LEDs every 5-minutes
Hold LED in left hand between index finger and thumb
Apply Epoxy down center

, Rotate 25-degrees in fingers and Epoxy down Center

, Rotate opposite direction 50-degrees and Epoxy down center
Place LED over appropriate DOT on heatsink
PUSH down with Right hand

Solder 1st Circuit (1st Foot) – Repeat Steps for 2nd & 3rd Circuit (2nd & 3rd Foot)

Check LED/WIRING Schematic
Wire Royal-Blue LEDs:
Wire Deep-Red LEDs:
Wire Reds & Red-Orange:
Wire Warm-White LEDs:

Kill a Watt · Feb 5, 2013

Complete EACH circuit with Positive & Negative Wires
For the Positive Wire use the appropriate COLOR WIRE for the color of the LED (Red Wire for Deep-Red Circuit, Orange Wire for Red & Red-Orange Circuit, White Wire for Warm-White Circuit and Blue Wire for Royal-Blue Circuit)
Use Black for ALL Negative connections

Cut ALL these wires long enough to run to the side (where drill holes will evenutally be) and be run up through the heatsink with enough wire to work with

Drill Holes for Wire (See above pic for reference)
There will be six holes per side
Run Positive & Negative wires neatly and in the straightest path to the side of heat-sink and determine where all the holes need to be drilled. Mark & Drill.

Kill a Watt · Feb 5, 2013

Run Wires through Drill-Holes & Tape to the side of the heat-sink
Solder Positive & Negative wires to Positive & Negative Output Wires of APPROPRIATE LED Driver:
(700mA FlexBock for Deep-Red in Boost-Only Mode)(700mA FlexBock for Red & Red-Orange)(1000mA BuckBlock for Royal-Blue)(1400mA BuckBlock for Warm-White)

Connections are made by stripping back both wires, adding heat-shrink tubing to wires

, Solder wires together and cover connection with heat-shrink
Cut away excess wire before stripping to save space
Cut away dimming wires and tape over end of wire
Special Connection must be make for Deep-Red Circuit (see FlexBock Datasheet for Boost-Only mode connection diagram)

Kill a Watt · Feb 5, 2013

Locate ALL Red & Black INPUT wires on the LED Drivers and TAPE them to the side of the heat-sink
One-Foot at a time: Solder RED wire to RED Wire on LED Drivers, long enough to stretch the length of the heat-sink
One-Foot at a time: Solder Black wire to Black Wire on LED Drivers, long enough to stretch the length of the heat-sink
Connect ALL Red wires to each other (see pic above)
Connect ALL Black wires to each other

Kill a Watt · Feb 5, 2013

Connect ALL Red wires to the Red wire on the 2 Conductor cable
Connect ALL Black wires to the Black wire on the 2 Conductor Cable
Heat-Shrink Red & Black Connections to the 2 Conductor Cable
Connector 2 Conductor Red & Black wires to appropriate Power-Supply Output
Connect Power-Supply CORD to Power-Supply, Wire with writing goes to “L” on Power-Supply (see pic above)

Kill a Watt · Feb 5, 2013

Plug in the Power-Supply to TEST that the 1st Foot Lights-Up!
Repeat for the next two-feet
Epoxy Drivers to side of heat-sink

, while the Epoxy is drying the drivers may need something to hold them against the heat-sink
Position fans, writing up
Run Fan wiring to central location

• Cut excess wire
• Don't use yellow
• Attach ALL REDs, Attach ALL Blacks
• Strip off barrel plug on 12VDC 1.0AMP fan power-supply and expose wires, wire with writing is Positive
• Attach and heat-shrink RED wires to positive wire on power-supply
• Attach and heat-shrink BLACK wires to Negative wire on power-supply
• Hide excess cords and wires along edge of heat-sink and run plug out with the other wires
• Attach rubber end plugs (use soap and water)
• Attach end caps
• Attach Hangers

alright, update time.

some things i noticed about this led fixture... it keeps the room warm. i don't need to exhaust the heat out. also, the leaves stretch very nicely from the light.

Kill a Watt · Feb 7, 2013

I have a blackberry kush and super lemon haze clone in the herd also

2876 is blackberry kush

2875 is super lemon haze

the last one is alien blackberry

What was the final cost on the light fixture? Looks great!

Bumping Spheda · Feb 7, 2013

I really like how you epoxy the drivers to the heat sink. Nice thinkin'. 8-)

Happy growin'!

awesome shit dude! cant wait to see this play out...

greenghost420 · Feb 7, 2013

i been looking to built something nice like this but been too lazy to map it out, good looking out!
