No its just the store bought netting for 7 bucks.
DirtHawkers first indoor aero/nft "stinkbud design" medical grow

Will do, but just by looking at it now i can already tell there is way more bud sites with the netting. I am putting in my next batch tonight, it has the net too.

Exactly... just start hacking away until there is as Kobe bryant says 'nothing but net"

Hello, nice show bro,
I think I may have whizzed by it, but what was your final numbers on your 1st show?
Congrats on the cheese, it sure sounds delicious when baked haha

yoda..thanks for the encouragement...my first harvest was only 8 plants and i got 9 ounces. since then the harvests have been bigger everytime..my next with co2 should yield a lb no problem.
Those of you using this system know that its best to have plants roughly the same size when they go into flower.. otherwise they get dwarfed and never amount to much..
I have my next batch ready to go into flower, but 2 out of the bunch are only about half the size...i was thinking of just putting those 2 into flower alone for maybe 2-3 days, so they can stretch a bit..all the while his classmates in veg can also be switched to 12 and 12 but remain in the veg closet.
what do ya think?

I don't know your current lighting situation, but for me, just the switch from a blue source(MH) to a red source(HPS) tends to stretch the plants without effecting the photoperiod. That way, they'll stay on the same harvest requirements and nute load requirements as the rest.
Might be worth a shot.

Sounds like a good plan to me. I've had a few not get enough light and end up being 8" tall and pathetic! Good for a CFL joke, haha.
I modifed the first unit with a screen today. Looks like it will work nice! Any more good ideas I can steal? hehe

oooooooh, that looks sweet revip
Out of curiousity, what numbers are you getting per yield?

Nowhere near as much as DirtHawker!
Though maybe with the CO2...
Speaking of which... my room gets entirely too hot/humid with the exhaust fan off while running CO2.
Does your dehumidifier keep up? What about the smell?
I'm finding the smell to get quite strong in as little as an hour without the exhaust fan (and carbon filter) running. Maybe I should wire the exhaust fan to run as slow as possible while running CO2 to cutback on loss but still improve smell. Or else get another carbon filter and simply recirculate air inside the room...
I really like the CO2 controller--it really is the way to go!

I wonder if the carbon filter wouldn't pull the CO2 out of the air in a closed system?
I had the same problem in my wardrobe and I solved it by just running the system on a shorter cycle -30 minutes of CO2 and then 30 minutes off and with the vent fans running. Maybe that is too wasteful for a bigger room like yours though.

You mean the carbon filter would absorb CO2 from the air? If I were to get a second one to cover up smell and simply recirculate the air.... good point! Oh right... duh!
Was just reading up on carbon filters and found " A relative humidity of 60%, it has been observed, is the upper limit beyond which filtering performance drops sharply. The relative humidity should therefore not be allowed to exceed this limit." which was more bad news for me haha.
I resorted to 1 hour off, 15 min on for the exhaust fan, with the CO2 controller still set at 1500 ppm but the smell was still pretty strong. Will have to think about it. I have a variable speed fan controller on the exhaust fan--the lowest setting works well, but it's an 8" fan so it still moves a lot of air.. if I could slow it down even more or use maybe a 4" fan and slowly vent with that, I could supply CO2 continuously with no smell, heat or humidity issues. Surely it's wasteful, but hopefully not too bad.

The outside weather really dictates my humidity level, even with my dehumidifier. If its humid outside my RH is up around 60+.
Lately i drain the DH after everycycle day or night.
Ever since i cooled my lights the temps in the room have not been a problem. My co2 is set to come on for 30 minutes every 3 hours, with the exhaust fan coming on for 15 minutes before each injection. The smell gets stronger all the way up until the next exhaust-co2 cycle. where im at smell isnt to big of an issue, i run the lights at night so it gets stinky all night. during the daytime when lights are off my exhaust is set to run until lights on.
seems to be working pretty well.
I really cant wait to pick up a greenhouse controller....hey rep i like your screen .. is that wire?

Yeah it's just poultry wire... you can get it at any hardware store by the fence supplies. It was the biggest netting I could find--couldn't find any plastic/rope and didn't want to make one. This should be reusable as well. It's kind of a pain to cut up, but the right tool always helps haha
I think humidity gets out of control for me because of so many plants breathing in such a small area. Humidity goes up and the dehumidifier runs nonstop, which steadily increases temperature. Well, it steadies out at 90F and 60%+ humidity. I really hope to ditch HPS altogether soon.

Yeah, I've also read that scrubbers are not only ineffective in high humidity, but that high humidity is the #1 killer of a carbon filter's usable lifespan too.
When you know, post up how the new schedule works.

Rep, I had heard you can run the scrubber inside the room and it wont affect the CO2 as long as its not exhausting. I plan on running an open scrubber when I add co2 and just exhausting my lights. Should clear up the stink issue!

I finally settled on 1 hour off, 15 min on for the exhaust timer. The smell was fairly strong this morning.
I like the idea of hardwiring the carbon filter+exhaust fan so that it is constantly supplied with a minimal amount of current to drive it at a very low speed (maybe 50 cfm or better yet 1/3-1/4 speed it would take to empty the room in one hour), during the day cycle when it would typically be off. When the exhaust fan is supplied power (nightime) it would then act like normal.
The CO2 controller can make up for the lost CO2 easy enough, which should hopefully be minimal.
This would be a way to prevent any smells from leaking out, and hopefully help the other issues.
Anyway... just ideas at this point. Solve one problem and create two more!

Thanks torrey!
I was reading up on this for awhile earlier and couldn't find any real specifics. At least, I found info which made me believe it would adsorb CO2, but nothing specific about the application of using a scrubber in a sealed system with CO2. There are carbon filters designed to catch CO2 though. However, my intuition tells me these regular carbon filters aren't going to affect CO2. I'm not sure why, I could be wrong... but I can for sure find out now that I have a ppm monitor. I love this thing. I will let you know!
Ha, it was one of the things I found out by paying for the "elite membership" The answer was tucked away in the advanced growing section there. I also dont see how a carbon scrubber would take out the CO2 unless it was specialized.
Which CO2 monitor did you end up with?
