Grow room:
1200 watts LEDs, all Cree 3.5watt LEDs, broad spectrum. Temps 75-88f

Planted on apr 24:

2x kush van stitch
2x la diva
2x himalaya blue diesel
2x biodiesel mass
2x ultraviolet*
2x sour diesel haze

Only 1 sour diesel haze sprouted and lived, after three total planted. * Additional ultraviolet, sour diesel haze, and HBD planted after original date (29th) when some originals did not sprout

Totals:

2x kush van stitch,
2x ultraviolet
2x biodiesel mass
2x la diva
2x HBD
1x sour diesel haze

As of June 2nd, six small plants, five big plants. * Small plants are:
1x ultraviolet
1x la diva
1x HBD
1x sour diesel haze
2x kush van stitch

June 4th:

Small plants are approx. 18" tall, fairly uniform
Big plants are approx 30-36" tall, some bushy, some stretchy*

Big HBD has an odd pheno with very large leaves and huge fans. It has just started flowering. **

Small HBD was the first plant to flower, and already has about 30-50% red hairs. **

I expect the small HBD to be the first plant harvested, with the large HBD to be the last.

Both biodiesel mass are huge. *One is the largest plant, but the HBD may overtake. *Largest biodiesel mass has issues with necrotic leaves. *It grew so fast early, I think it's burning itself out

Sour diesel haze is very shirt but bushy pheno - looks very healthy

Both kush van stitch are short, bushy, and healthy looking.

June 7th:

All plants seem to have stopped vertical growth, except for the big HBD. *It has slowed its vertical growth considerably. *Small HBD leaves are starting to droop-- *its buds are getting huge-- *I think it's going to have a very short life cycle. * About 70% of the hairs are red. * Lots of trichromes.
Bigger of the two biodiesel mass is producing a huge amount of trichromes.*
Big ultraviolet has buds almost from the top to the bottom of the plant. * Will be a huge producer.


June 16:

Big HBD finally starting to put mass on the buds. Both ultaviolets doing great, huge colas. Both KVS exceptional bud mass-- but one smells like kerosene, the other like bubblegum. Very different smell, very similar phenotype (short, bushy, big cola)
Both biodiesels are still large, but both are dwarfed by the big HBD. It's probably about 40" tall now.
Small HBD continuing to put on bud mass, thanks to Mossy for advice on harvesting!

Fertilized with bloom booster and molasses on 16 June. *Should start flushing on 1 July*

What spectrum you using for this grow?....that a hell of a lot of LED power you have there.

420nm blues, and wide spectrum whites right now (all Cree). Next week I'm hoping to add some Osram hyper-reds to the mix.

The Osram efficiency numbers are incredible--- 48% light conversion efficiency. I'm hoping to be able to back down to 600-900 watts after adding the osrams into the mix.
 
Yeah get some red in there dude lol u seem to know your chips,do you know much about the Philips Lumiled?

Well.... I'm an EE, and I design LED fixtures ... Guess I better not say more than that...

I know a lot about the lumiled- is there any specific questions you want me to answer about them?

I would say that for white and blue they have good numbers. The packaging is a bit of an issue though. Most of the lumiled packages have a 180 degree beam pattern, which means they need secondary optics to focus them.

A lot of newer lighting class Cree LEDs have the same wide beam. Great for office lighting, bad for horticultural lighting.
 
And when I say bad--- I mean more expensive because of the need for secondary optics.

The Cree LEDs I use are the XRE package with a 90 degree beam. The osrams are available with 80 degree beam
 
2 of my lights use 5w chips with 120degree beam angle and they work great,check out my grow diary. I recently spoke to the guy who designs the lights I use and he has some modules out the end of the year using the Lumiled.
