Firstly, thanks to Manic for allowing me to test seeds for the first time - promise I won't let you down, homey :) Apologies for the length, but don't want to forget anything and would like to do a good job documenting this to pay Manic back for the honor of testing for him. Let me start...

By Nathan Koppel It has not been a good 24 hours for medical marijuana users. Michigan federal judge Robert Jonker today ruled that Walmart had the right to fire an employee who was using marijuana to treat the side effects of an inoperable brain tumor. The state’s medical marijuana laws...

Anyone know? I mean, if you're running an accumulator setup, the water leaves your reservoir, and gets delivered to your plants an hour or two later, at which point it has reached (damn near) room temperature..........so why the chiller? There's so much DO available to the roots at all times...

Quick and to the point - have four 1/4" solenoids which will all be controlled by the same ultra short cycle timer - both the timer and solenoids run off of 120V. I've wired up a few 120V solenoids already (just go to Home Depot and get the cord with the three loose wires at the end and...

Never been to Montana, but this article is awesome (lifted from The Journal): On the Great Montana Marijuana Mutiny By Ashby Jones Wowza. This has to be the most extreme example of jury nullification we’ve ever heard of. More like not-yet-a-jury nullification. Let us explain...

Long story short, have a crazy contraption that's powered by a 1/6HP utility pump from Lowes (Utilitech), and it works great - my only issue is that the pump eats up 600 watts, which for me in a non-med state is a little more than I'd like, especially as I contemplate having the pump running...

I know that there are prefilters for inline and pond pumps, but does anyone know of any similar products for utility/sump pumps? I run a 1/6HP pump to feed my system and would like to do everything possible to keep my sprinklers clean - anyone know of anything out there? For some reason I...

Before you start, this email I sent to Hydro Innovations is long, so back out now if you don't have the time to read it..............anyways, any flaws anyone can see with my logic would be much, much appreciated - please people, talk me out of this (but do so logically given the parameters I've...

Really quickly - couldn't find 5/8" inside diameter black hose (both HD and Lowes were out of it), so I had to grab some cut garden hose from Lowes (5/8" inside diameter, obviously) as my input for my chiller. I read on another forum that using garden hose is a no-no because of the interior...

I know there's been a fair amount of threads regarding dual arcs lately, but this is kind of a specific question. Running four stacked 600s in a vertical cooltube, and have two HPS and two dual arcs and I was wondering what people's opinions were of the best order for the bulbs to be in...

Long story short, needed to buy two 1/6HP pumps to run my new system, and I wasn't planning on that amp draw (only run for a couple of seconds every few minutes, but they need their own circuit) and the 3 20 amp circuits that are already in there are all spoken for with lights, chillers, etc...

Looking to get the most efficient heat exchanging Cool Coil-type thing they make, and this seems to be the brewer's choice for speed in bringing temps down: It's made of stainless steel that's "fused" together with copper in an oxygen-free environment? Can any of you chemists help out...

I know for the people running bennies this wouldn't work because it would kill all the good stuff, so no Roots Xcel or anything like that would be able to run in the system. But I know there's lotsa people like me who don't let anything live in their system and use 35% H2O2 religiously to...

As I've been doing some searching on the Internet, I've found some interesting things - namely, that there are tax breaks for a decent amount of things that we use in our grow shows. Tankless hot water heaters and mini splits are two of the things that caught my attention immediately, but...

Not sure if this is the right forum or not, but seemed like the best fit to me. Anyhow, the question is why 1500ppms is the "accepted" rate to run CO2 at - if I understand, plants evolved to be able to use CO2 when the concentration was closer to 2000PPMs in the atmosphere, correct? So why...

Okay, have searched this site, others, and the Internet in general and am trying to come to a consensus (from people who know) about what the "ideal" amount of lux/footcandles hitting plants would be for flowering. Setting up a DIY Coliseum grow, which will have four 600s (5 or even 6 in the...

Sorry in advance for the long-windedness. Firstly, a really quick hello (again) to all you farmers out there. Secondly, tore my old setup down, selling it, and am going to start building my new setup within a week (hopefully) when I've gotten my garage emptied out. I see a lot of...
