This has had alot of great information and it seems the 3000k at 90CRI would be recomended over the 3000k or 35000k 80 CRI. I happened upon this graph which seems to say that 80 CRI would be better because of higher amounts of reds (if im interperteing it right). What do you think about this...

Thanks for clearing that up guys. I was looking at relative spectral power as a variable that would adjust not simply a descriptor. Makes since now. what do you guys think is the best chip for an LED to be used veg and flower. Its the Vero 29 there is the 3000k and 3500k 80 CRI in the D...

Looking at this graph, the higher the relative spectral power (y-axis) the less usable red and blue spectrum is available. Using 3000k, 80CRI if I am at 70% relative spectral power, then I am not getting any blue spectrum and a smaller amount of red spectrum. Whereas down at 30%, I get blue...

So after looking at spectrum graphs it looks like 3500k is the best all around temp. However looking at the charts of one in at full intensity I only get a small portion of the spectrum and I I run at low relative intensity I get the majority of the spectrum. My question is how is relative...

Even if I scrog on both sides I still need a way to reach the back plants. I don't think I can reach 4-5 feet to train the girls in the back. That was my reasoning for the "walkway" I'm all for more grow space of you think I'll be able to reach the ones in back. Reaching That far to tuck...

Thanks for the input. I will be growing all one strain from fem seed. I want to see the difference between the two methods and throwing the variable of different strains would make that a little more difficult I think. That being said I was thinking of NL#5 again or another indica Dom strain...

Ok guys here's what I've got going. I have a 5x5 tent with 800w cob led lighting and a top drip hydro system. I need some advice on the best grow methods to maximize that space. I was thinking of splitting the tent in half and doing 3 plants scrog on one side 2x5 and mainline 3 plants in the...

Tacomac, I got another one for you. I just went to buy the lights from timber. They have a cool chat feature. I spoke with Dan and he was saying that I need 30-50w per sq ft meaning 500 watts would be the low end of what is sufficient for 4x4. Are these numbers exagerated by seller or will...

That's exactly the info I was looking for. Thanks for all the help bud. I will update with a log when I get up and growing.

Awsome, thanks tacomac! I've never done scrog before but I've done a standard grow. I was tossed up between 4, 5 or 6 plants in the 5x5 and I know the number of plants for space is determined by how long you veg. For 8 week veg you recomended 4 plants. If I veg 4-6 weeks and used 6 plants...

Thanks Johnny. Your first post didmt show up until I just now viewed it. Thanks for the links you guys have made this A lot easier. I am suprise you say the platinums are crap. They are expensive but I watched a live video of PAR and spectrum and the numbers looked pretty good. The wattage...

Thanks tocomac. That takes a lot of the guess work out of it. Is there any light quality difference between citizen and cree cob lights? Also, in all of my reading about led grow lights the important thing was PAR and light spectrum high in blue and red and not much in the middle because the...

Thanks for the replies. I'm debating whether I should build or just buy 2 platinum p300 for my 4x4 or 5x5 space. The 2 would be right at $700. What would you estimate the price of diy cob for 5x5 space? If its a difference of $200 then I would pay that to avoid the hassel of making the...

Hey guys I could use some help from the experts. I was looking at growmau5 diy cob led kits at cutter,com,au and It seems one of the single 3590 lights puts out max 137 watts which means i should get 4 to cover my 4x4x6.5 area as I read I should have ~32 watts per sq/ft. Then I look at the 4...

Hello, I was looking at your kits and one of the single 3590 lights puts out max 137 watts which means i need 4 to cover my 4x4 area as I read I should have ~32 watts sq/ft. But the 4 light kit runs at 50 watts ea. 200 total watts i don't think is enough power. With the same kit and a...
