Another Cree CXA3070 DIY Thread

I was wondering about the flower initiator. According to the man that sells them: http://growlightsource.com/products/the-flower-initiator-and-booster-grow-lights/, one 20 watt light (730 nm) is good for 16' x 16' = 0.16 meters. For 1 square meter you need 6.25 of those 20 watt leds, 125 watts. The efficiency is max 7.2%, so you have 9 par watt on 1 square meter. If you choose the osram ssl and calculate the watts you need based on their efficiency (36%), you need 25 watts. Major difference if you ask me.

My problem now is: do I put the Osrams on a different circuit so I can switch them off seperate from the 3070's (or let them on for 7 minutes after light out) or should I put them between the 3070's in series? If I put them in series with the 3070's, they (maybe) will not go fast to sleep when the lights are going out? Or am I mistaken?

Last run I used two 10 watt red epileds (with eff of max 7%, and up to the cealing) with a light schedule of 13.5/10.5 and had no hermies. Strange if you ask me... Or do the plants not use the low par light in the epileds? Can anyone clarify this to me?
 
I think that GrowlightSource dude is blowing fishes, to get more clients...
Someone in forum stated, that one 730 fits for much larger tent... like 10W for all tent.
 
That explains it....when using 625 watts for my growing room, the plants shoot through the roof I think. Thanks for your reply.

How do you know that these are epileds chips?
