Mephisto Genetics Mephisto LED vs HPS Sour Crack AF-SOG!

[Margahooja]

If those HS1s were hung more diagonal, would the coverage be any different?

Damn! That HPS is rocking!!! I may need to look into that for future use. It'll be very interesting to see how the 490 actual LED watts in my tent compare to the 600 watts of HPS. Great growing and thanks for making time to update!

It's a surprising difference than what I thought it was going to be. I'm anxious to see how they progress.

Main thing is everything looks healthy
They're all on 24/7 now, We have another tent running now for upcoming seed making
So, It'll add more heat and we'll be able to knock the hours down.

Still, very very early days!

Have you always been LED gbd?

If those HS1s were hung more diagonal, would the coverage be any different?

The design of the hs1 means the lighting is not central to the unit, it's eminates from one corner.
They were set up so they were facing the opposite ways to each other to give, what I thought the most even coverage.

I had to do a fix on them both a few days ago, and so i'll re-set them up how they were.

Also the new tent has a parabolic open shade, so i'll do some testing with the light meter with that to see just how even the coverage is with that style reflector.

Cheers!

Yes, sir. CFLs for a few days while waiting on my first LED, but that's it.

WoW, I did not think it would or could be such a big difference this early on...but....wow. I like what I see because I am an hps guy and those led are so damn expensive anyway.

edit: Looks like those led are more for growing one or maybe two plants at a time, but with an hps you can grow many more than that. Making the led in a way even more expensiv.

This is the big down side with the led light during winter time to me, its hard to keep up with those temps without a heater. And a heater is a big watt eater. But in the summer it is the other way around with hps bringing temps up like crazy tho..

Its winter here and I'm using an 80w tube heater for an hour a day so very little energy used on heat,if you grow outside in a shed I can understand your point but most home growers grow indoors which will more than likely have central heating.

Day 10 from sprout update:

HPS tent - on 600w since yesterday

LED tent - My feeling is the 6th row (closest in shot) is not getting so much light - plants still growing of course, but coverage of the remainder seems good.

Comparison - Picked a nice sized HPS and a nice sized LED grown.

CHeers all.

Something VERY wrong here bro in my opinion the lights look to hight and your temp is way to low for growing under LED.

have a look at the first 5 mins of this and it shoud explain better than I can here [video=youtube_share;xJIjJ5nZUZw]http://youtu.be/xJIjJ5nZUZw[/video]

Excellent video. Have to agree with Tang's comment, the setup looks wrong and since it is very unclear what the temperature Min/Max/average are in each tent, this is not a good comparison grow........Even Stevens don't spring to mind.

Found this, and for the money it seems like a worthwhile gadget to have around when doing this type of comparisons

Yup, but if he lowers the light he will not get such a big spread of the light and will have to remove a lot of plants and maybe he dosent have central heating bro.
