I am in need of a very quiet air pump. Every bit of noise has been taken care of for a small DWC grow besides this. Anyone have any recommendations on an extremely quiet air pump?

What substrate are you using? I have found that this tek :http://www.shroomery.org/forums/showflat.php/Number/9289857 works very very well for mono tubs.

You give some great advice here, but I'm gonna throw in my 2c. For one, incubation is not necessary and actually counter productive if room temperature is between 65 and 75 F. I used to mess with TiT and all the other stuff, but at 70 F mycelium grows optimally in quart jars especially since...

So basically he is claiming they will last 20 years if you use solid wall PVC without any additional treatment. Whether or not this is an exaggeration in an attempt to gain sales is questionable, but I have no reason to doubt his claim other than my usual skepticism of all sales people. In any...

For anyone who is interested, I contacted the guy at: http://hydro-tubes.com/ and got a reply. Here was my question: "My main question is what is the pvc material you use for the tubes? Is it standard plumbing pvc? I understand standard pvc pipe degrades over time with exposure to UV radiation...

Ya man I like your system. For herb it's the way to go for sure. I'm only worried about NSF food safe because of possible FDA/USDA inspections if I can get big enough to require certification or whatever it is they do... my research into those areas has barely started, so I'm not sure.

Ya, I understand. I had a system built out of 6" PVC with 3.75" netpots under MH and HPs that went a good 2 years with no problems either. The thing is if I have to replace potentially thousands of feet of PVC pipe 4 years into using the system, the my entire business model is screwed... really...

Also, I do think those posts have been painted, treated, or are a slightly different material in order to be UV resistant because they are supposed to last 20 years outside in direct sunlight.

I was looking at those. Great choice for herb, but that is too expensive to grow vegetables in. Also, I don't need nearly as much space for root growth as these plants will mostly only live 35ish days. I'm looking for something that would be commercially viable for vegetable production, and that...

Thanks for the input guys. That's pretty much the answer I expected. I'm mainly asking because commercial NFT gullies are like $2.50 a foot (not including ridiculous shipping costs), while 3" PVC is like $0.79 per ft (or cheaper if bought in bulk), and I'm trying to figure out whether or not it...

Real simple question here, but I haven't been able to find the answer online. I am planning on building a hydro system for spinach, herbs, and other salad greens using regular 3" SCHD40 Cellular Core PVC. My question is, does this need to be painted to protect from UV rays? I can't seem to...

IMHO, spores to birdseed to pasteurized used coffee grounds and coir is the most cost effective way by far. Just spawn the colonized birdseed to the coir/coffee substrate at a ratio of about 1-10, and fill the bottom 3-4 inches of a rubbermaid container with them. Drill a few holes in the top...

How you grow depends on what you want, but what I used to do was buy spore syringes from www.sporeworks.com, inject them into sterilized jars of birdseed, and then spawn the birdseed to compost from www.tennstud.com into fruiting trays with a thin casing layer. This is the way you wanna go if...

Im in pretty much the same boat but it hasn't been as long. When I look up my tracking # it says that it arrived in NY on th 7th, but then there's nothing after that. I'm hoping they just don't update the tracking after it hits NY, but I'm starting to get worried they might've been nabbed by...

ughhh. he ducked out. I think he got a renter.

Thanks grow. I love any advice i can get.

Cool, that's pretty much what I thought, but I wanted to get some confirmation.

So, after comparing attitude to hemp depot, I think I'm going with attitude. Better prices and free seeds on top! I think I'm gonna go with one of the Green House mix packs just so I can try out a few more varieties. Thanks for all the help guys.

Thanks for the advice guys. I'm thinking about goin with some chronic from serious, but god damn that is expensive. 205 for 10 non-feminized seeds from hemp depot. Dutch Passion is half that, but I guess you gotta pay for quality. They had just better be worth it.

So, I'm gonna be setting up a new grow soon, and I'm out of genetics. When I started growing all I had was blueberry and white widow, and those two strains plus a sweet cross that I got lucky with lasted me about five years. Anyways, after I finished my last grow, I didn't keep any clones :wall...
