Greg Richter, who designed and built this light has agreed to issue IAGLA his 3rd party test results whereby a comparative analysis may be performed over the claimed area coverage. In addition to watts at the wall we want to know how intensities, spectrums, uniformity and penetration play out...

Today is day 55 and the 20 plants under the first light (L1) are done. I set the plants up outdoors in the buckets so you can see them in the light better. It's astonishing when you see them moved out into the sunlight to think all these plants were under one light! If you look closely at the...

Day 46 on the front set and day 29 on the back set. Since the last post I added a Sentinel CO2 controller and running it @ ~1200 PPM. I've also got the Dent submeter which you can see to the left of the electric panel working with the software to watch the main meter Time of Use and let me %...

Extending spectrum won't come into play with PALC. In fact PALC brings all technologies into a commonality whereby only the uniformity of the area intensity is being given a value regardless of the technology or the emitted spectrum. For example if one were to test the uniformity of coverage...

RIU is blessed with some pretty astute readers and contributors. But I've always believed that when considering the variety of grow lighting technologies it has been a real challenge for the average person to determine what it is they need to understand when comparing different grow light...

Day 30 (L1-L3) update. As you look down the trailers you'll see that we have 5 lights with 3 of them(L1-L3) set up on UV-Pontoons with L4/5 running with straight LED and no Pontoons. Also the plants under L4/5 are at day 14 of flower and they are all in Growpito spun rock media, not the...

No matter what grow lighting technology you might favor for your garden there are 4 basic performance factors to use when comparing between them: Photosynthetic Photon Flux (PPF): the total number of photons the light emits. Spectral Power Distribution (SPD): An SPD graph will show, In...

I think you're referring to Maupito and I'm not even sure their still around. Grodan seems to have displaced them. As to this spectrum we used a combination of 3500K, 5000K, 660nm strips and a small amount of the 730nm at lights on which is exclusively used at lights out to initiate the...

No cannabis needs additional nutrients that are not available in straight fish water. So we add trace minerals through a top watering every 4-7 days. The dosing system is a good way to give the plants what they need without introducing those trace minerals from heavy top watering that don't...

Day 23 of Flower Update and I must say the resin oil and trichome production is really good for not even 1/2 way there. If anyone wants to learn more about how we're growing with a Closed Loop Aquaponic System go to: http://151farmers.org/wp-content/uploads/2017/10/Closed-Loop-AquaponicsV1-1.pdf

Hey PSUAGRO! Yeah the CO thing was short lived. I can't handle partners I guess. I'm back in Diego now working the farm. We need to get together when you're able!

Thanks everyone. It's great to be back! We have been steadily moving along with the induction lamps since 2010. But the reality is that the industry is going to switch over to LED and really the time is now. IMO this light is packed with the features that should be available when using this...

I'm starting this thread at Day 23 from rooted clone (Day 18 of flower). I have 20 plants with a mix of Smash Berry and Blue Dream in 5 gallon buckets. The buckets are being bottom fed on a flood and drain system from a fish tank filled with Tilapia. I'm using lava rock at the bottom 4" of the...

Hi everyone! It 's good to be back! I've been growing cannabis with aquaponics now for about 4 years. What I'd like to demonstrate now something I've been working on that is a strategy farmers can use which I believe will optimize annual crop production values, on a gram/meter basis, by...

Just to clarify some of the misinformation, here are the facts. Darryl Cotton owns the property. He leased the front of the building to a dispensary. The City sues Cotton under a violation of Land Use Regulations that state the dispensary is in violation of zoning codes because there is no...

These are really fun competitions. It never ceases to amaze me how much work and passion goes goes into making your best effort in a 16 oz party cup. Bravo to those who choose to do so and share it for all to see. As to the prizes I would venture that for those who take a first place prize it...

yes coco with a mix of hydroton and the bottom 2-3 inches of the bucket is 1" black lava rock.

Damn bro those flowers are looking awesome! :clap: I don't want to hijack the thread but since we're analyzing hybrid lighting approaches I'll throw this in. I have also been pushing higher intensities in one one the flower rooms with a 1000 watt DE-HPS on a light running right between 4 of...

Sorry for the delayed update but it's been kind of nuts around here. Today I pulled a Mint Chocolate Chip out of one of the last remaining 1 gal pots this morning that smelled sooo good I had to share it with the ladies. Seriously they better start laying some eggs in the next few weeks...

I've seen more of the IG 420's going to the UK. Shipping isn't that bad either. What kind of kWh rates are they charging over there?
