The filter and fan are rated the same and bought according to size requirements. (4 min airexchange) The fan is actually on only 40% speed since it's cold outside and doesn't need that much circulation to keep cool but still there is smell. Setup is: Filter > 90° Turn > 2xcooltube 600...

Hey people, you guys have always been very helpful before and I'll test my luck once again with this little question/concern. I have a professional filter that I bought the other day. My plants are just vegging (10 ladies) but since I'm exhausting into my apartment it still stinks. When I...

I changed the res but didn't flush? What's an epsom salt flush lol. How can it be N def when they're at EC 1.7 with GH flora at 1-1-1?? I don't have an airstone in the res. More ideas I can try guys? Much appreciated.

These are critical mass, they're approx 5 weeks old (from seed). They started out in rockwool which was presoaked. They looked well the first 3 weeks until I put them in the Aeroflo. Then two died, wilting extremely and never really recovering. The others were droopy...

I don't understand... I Ph the water down to 5.6 and then it rises to about 6.0 over the course of 24 hours. There's slight wilting almost constantly, though I don't think that's very dangerous. I'm using equal parts Grow - Micro - Bloom (GH), maybe that's the problem? When I raised the EC...

So the title says it really, before I put my plants into the aeroponic system, do I need to do something? There are residues of pvc after the drilling, are these dangerous to the plants or could they hurt the system? Thanks a lot.

Hey guys, I‘m starting my grow and I‘m about to soak my rockwool cubes for the second time (5.5 PH water only the first time) and I wanted to know how much root stimulator I would need? Well of course you won‘t know the strength of my stimulator, so rather, can too much damage the...

Wouldn't the air being blown out be more noticeable? If it stinks I don't want it outside. IR can pick it up. If you walk past it you'll hear a lot more noise? thank you for your reply. I'f be interested in knowing how you would exhaust without anyone noticing, at least with what I know now...

Hey guys, I'm very hesitant to take the final step and purchasing all my equipment until I'm sure of the design for my growroom. I'm from Europe so I won't have the specific words for construction stuff or what have you (Also it’s pretty cold over here). So here goes nothing...

Hey man, thanks for chiming in. What's the benefit of building a tent? Would you use pandafilm/plast for the walls and could you make it out of pvc pipes and fittings?

Thanks, that's exactly what I'll do. All of the replies were really helpful in my decision, one less loose screw in my head. Again, much appreciated.

Hey guys, my undying love for the greenz will soon be materialized, but until then I need your sage wisdom on how to make the growing facilities into reality. Right to it shall we? Issue: It's a rental, drilling is out of the question; so no nails or screws in the walls or ceiling...

I appreciate the reply. Why the big duct? Any specific reason. If the small window is an exhaust wouldn't people hear it clearly if they'd be snooping around? How small is too small for a passive intake (ie. exhaust through the door and into the house)? Any more brainstorming would be gold...

Hey there guys, I've been reading for a while now and I'm still very uneasy about how to set up a grow room, particularly the exhaust/intake side of it. I have a room that's 7' x 10', so plenty of space to fit an Aeroflo 28 with a 600w HPS. Here's the problem, there is only one window in...
