A couple of thoughts. If you have more vertical space you should add more height to your grow box. Heat can be an issue in tight spaces as is stretch. Also the light you linked to is just a hood. You will also need a bulb and ballast.

I know people are building flat panels but is it possible to build a vertical LED configuration as a DIYer? I was think of a series of thin panels that were joined together in (maybe) an octagonal shape and then suspended vertically. Would it be possible to build something that consumed around...

Are you using you reservoirs as heat sinks? One main res with chiller cycled through RDWC res' using wort chiller type design. What am I missing? Also - I like the vertical trellis idea especially if you can keep the plant count down but unless you are actually pulling 3x product with 1/2 Kw...

For anyone with serious medical need for RSO I would highly recommend making your own. 2/3rds of a pound of flowers should make 60 grams of RSO. It is a simple extraction process that is easy to look up. When you buy RSO from most clubs or growers they are using their trimmings to make the...

I believe the 70% rule is the case for dispensaries in CO but I don't think it has anything to do with OR.

I'm interested in aquaponics but from everything I have read having a small reservoir means very little buffer. 250 gallons was the minimum fish tank size recommended. Best of luck.

Firstly - I believe that grams/kilowatt hour is what is really important. The reason why SOG would be ideal without plant limits is because you skip the veg almost entirely. This time savings adds up to better quality because there is less time for pests etc. If you have a plant count...

Its been said 100 times before but here it is. Apache Tech makes the best panels if cost is no object. Area 51 makes the best bang-for-buck panels. You can hang the 190 watt area 51 LED panel about 3 feet on center. The AT600 has at least 4'x4' coverage.

I'm not a noob to growing but I've realized I know little to nothing about fertilizer. I've just followed a watered-down manufactures guideline for a simple A + B product. I am interested in growing the best medicine I can which includes flavor and I want to be as environmental as possible. I...

Can you not do living organics and hydro? Sorry if thats a dumb question - I've just started reading.

Is there any side by side grow journals or other testing that shows an increase in potency vrs. HPS? I've read some chatter that LEDs can pull an extra 3 percentage points from a plant. Does anyone have personal experiences to support this claim?

hyroot - you seem to really understand all the brews really well. I'm a hydro guy that's always just both nutes off the shelf. Where can I read more about making my own teas etc.? I think this is probably a big hole in my learning.

newtoMJ just stated he got over 2 grams/watt from two generation ago A51 LEDs. I suspect you bought inferior panels or you are running your room too cold. Bad Karma is crushing it with LEDs!

I run LEDs so room temp and canopy temp are pretty close.

I've been reading as much as I can about ideal temps. The general consensus for RDWC systems is 68 F. I read that the ideal temp for plants to take advantage of Co2 is 85 F @ 1500 ppm. I downloaded a VPD calculator and the ideal RH at 85 F is 79%. I understand there are issues with different...

Subbed. Very excited about this light! A couple questions if you don't mind. I read on another forum that you were prototyping UVB tubes with LEDs and that NASA and Stanford run them. Do you know any more details about how they supplement with UVB? Do you plan to turn them on the last two...

PSUAGRO, Have you ever grown with LEDs? I know 1 gram/watt is impressive with HID. I'm not sure the rules apply to the new LEDs coming out but time will tell. Not all watts are created equal. I'd be happy to pull a pound with 600 watts of HPS (and have). I would hope this is equivalent to...

This is about as well said as I have seen on any forum. People still believe that a watt is a watt is a watt. How efficiently those watts are used is most of it. IMO the Mars II probably gets good results until it breaks but they aren't as efficient as their HID counterparts watt for watt let...

Its under 30 feet from the back of my house to the likely panel location. My breaker box is underneath my house towards the front which would add another 20 feet. From that panel to the edge of the house would be pretty easy. There is a cement and pebble walkway that is between the house and...

Thanks Devilspawn - I'd take quality over quantity any day of the week. My area is saturated with mid-shelf medicine. I think top shelf moves east - I just know I don't see it.
