This is a test grow -- testing both the marijuana strain (ONYX) and the LED grow light being used for the grow (180 watt Pro Grow LED).

Onyx -  purchased from Attitude Seeds
Pro Grow 180 - purchased from Hydroponics Hut

I purchased some ONYX seeds ( Short Stuff) and a new 180 watt LED PRO GROW light from Hydroponics Hut both around the same time.  Between holiday craziness and some health issues,  I was unable to work with either till now.  So, it makes sense to test performance of both at once in this grow.

I've got a special spot set up in my indoor grow area for the ONYX.  I have the Pro Grow 180 safely hung and set, for now, at an 18/6 light schedule.

So let's get this show on the road!

Grow Factoids:

Onyx is an autoflowering strain developed by Short Stuff breeder Stitch.  It should give higher yields because it grows a bit taller than the typical 'LowRyder' and other auto-flowering strains, reaching a height of ~ 24 to 30 inches.  Its a cross of several devastating strains, and breeder Stitch says the potency of Onyx IS devastating.

I purchased Onyx from the Attitude seed bank, and you can read more about Onyx and other Short Stuff varieties there.

Three Onyx marijuana seedlings.On 1/2/2011 I dropped three (3) Onyx seeds into a cup of water to soak for 12 hours.  Then using the paper-towel method, all three seeds sprouted tails within another 24 hours.  At that point I placed them about 1/4 inch deep into 4-inch pots containing a 50/50 mix of OMRI certified organic Black Gold coco blend and Roots Organics soils.  About 2-4 days later all three Onyx had sprouted up above the soil.

The photo in this post was taken on January 18th - seedlings a little over a week above the soil.  I think these Onyx seedlings look rather happy, don't you?

Pro Grow 180 watt LED Grow Light - the Pro Grow line of LED grow lights is exclusive to Hydroponics Hut.  I've purchased several LED lights from Hydroponics Hut.  Maybe you followed the 550 watt Pro Grow journal I started a few months back ...

Anyway, the 180 watt Pro Grow also uses high-output CREE bulbs just like the 550 watt.   The difference, of course, is that the 550 can handle up to ten plants (or a 6 foot x 6 foot area), and the 180 can handle up to 3 plants (up to 4 foot x 4 foot area).  You can get the complete specs and details on the LED grow light using the links above.

The grow area is in a finished basement (dry, insulated, heating ducts, etc) that stays in the range of 64-69 degrees in the Winter months, with heat ducts closed.

I'll post the next update when the seedlings show some growth.

Here's a couple more shots of the plants under the light - you can see the two switches that control the light spectrum.
