Heya everyone. Welcome to what should be an interesting journal.
In this one we're making a test run of GreenSun LED's Cob Style. Amy, our rep here at 420mag sent me these to do just that. Test and offer thoughts and opinions.
These two LED's draw 109 watts actual, each. They are 3w chips. Seems low total wattage draw for my style of growing so I'll be forced to keep them smaller. A nice small flux method should work well.
There are 24 chips per cob, using an aluminum reflector, 93 degree lens angle.
Area of coverage and Lux:
0.8m (31 inches) height = 3890 lux, coverage = 2.43sq meter (95 sq inches)
0.6m (23.6 inches) height = 8790 lux, coverage = 1.62sq m (63.7 Sq inches)
0.4m (15.7 inches) height = 13450 lux, coverage = 1.43sq m (56 sq inches)
Using two lights for 3 plants should give me plenty of area coverage. But I worry the low total watts may be too little for full penetration with say anything over about 20" max height of plants.
Temps are running 81f at plant base with lights 22" above.
What is cob style? Cob style is several chips of different spectrum on a single board. Driven per board.
My grow tent is 4' x 4'.
Running 3 x 5 gal buckets, plus main res, in RDWC style, self built, using 1.5" pvc. I use a 396 gph pump, pushing through a 1/10 hp chiller. Water temps are kept at 67 degrees. All four buckets have one 3" air stone.
These are 3 Holy Grail Kush clones I took from my other grow that's in flower right now. This is an awesome strain with great reviews.
These pics are from the first couple days after transplanting into the buckets.
I topped these plants maybe 10 days ago, and topped them low for the flux style. The following pics are from today. I've only "pushed" the branches lateral a bit. I don't have what I want to tie them laterally, and mostly they are too short to do so as yet I think.
Thanks for joining in, feel free to comment, lets have a good time!

Ill be here for any info etc. My phone battery is about to die so ill be back 
Count me in!
. Im new to dwc/rdwc systems, so i wanted to ask do you clean your buckets during grow? And if you do, HOW? Or do you just drain the water out and put new in? If doing scrog for example its kinda impossible to take buckets out for cleaning with some monster bushes
