I stopped using GH & AN due to the bio matter is leaves behind in my system. I'm a firm believer after 5+ years using RDWC that things need to be sterile as possible when going from a small DWC(less than 4 plant modules) to a more commercial RDWC setup. I've battled clear slime, random snot...

I just switched to Cultured Solutions nutrients from Current Culture from advice from a fellow hydro guy. I never gave them a thought seeing their systems are ridiculously expensive. To my surprise their nutes aren't crazy expensive at all. Super clean & most of all they're crystal clear when...

I made the switch to RDWC to accommodate a larger root mass. Here's a couple recent pics of one of our licensed MMJ flower rooms in Michigan. The first pic is the day we transplanted them from a 30 day veg. And the second one is that same garden a week later. It shows that with an increased root...

Good stuff. That's the exact style I started with when I started out. I was growing basil & tomatoes on my patio then graduated to real herb. They work really good, just lots of root build up. Clone to flower works best in those & definitely scrog. Pack'em in tight with little or no veg time at...

Thanks man. I found that I can use a much smaller chiller when using the beer cooler method. The nute temps never fluctuate. They stay @ 67°F without any issues & each system holds about 90 gallons. It's been working wonderfully.

They don't leak at all. Not much tightening is needed. I put a bead of high quality silicone sealant around the gasket of the bulkhead on the side that contacts the inside of the cooler, pop it through the hole & tighten the nut as hard as I can with my hand. Then give it a quarter turn with...

The systems I build use 2" Schedule 40 PVC lines for flow between grow modules & 3/4" vinyl for the return back to the control module. I do however use a separate 250gph pump for the 1/10th HP chiller I use. I match the system return pump to how many gallons I want to move in an hour. My...

Do your self a favor and dump the cfl idea, I've been down that road. I guessing your 4x4 area isn't for profit so I'll step out and assume you are a hobby/connoisseur grower, right. Save some future $ and pickup a 600w dimable digital ballast($199), bulb($60), a cool tube & fan($100), run it at...

Hey Pr0f, Great thread. I cant get the help I need, too many people arguing on off topic BS. What would be a good choice of T5 colors if using them in side lighting? I'm planning on 4 fixtures with four 4' T5's, one on each side of the flower chamber.

I'm almost ready to assemble my new cabinet(40" x 40" x 7'). I did change the quantity of T5 lighting I'm planning on using. My original design was a larger room split into 2 spaces. But now I have decided to use separate cabinets for each flowering setup. I am an LED user already(jumbo 180), so...

Ordering some remote ballasts this week. Planning on a 6 bulb on 2 opposing walls in each side of the setup...

Is anybody running their ballasts remotely outside of the grow space to save on heat? I found a site that sells remote ballasts pre wired for HO T5's. http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=19811&cmpid=03csegb&ref=3312&subref=AA&CAWELAID=525426348 I'm re-configuring my...

First of all...I agree with what you have done using aquarium bulbs! I'm in no way trying to insult you, so calm down. And yes I agree there are different variables when talking about yield, just wanted a rough figure, thats all. I built a custom enclosure that is 6' wide 3' deep & 7' tall, then...

Great work pr0fesseur!!! Just got done reading all of the thread & I have a couple questions. 1) What king of dry yields per m2 are you getting out of these lights? 2) How much heat are they throwing off? 3) what do you think about mixing them with high quality L.E.D. fixtures?
