SGFC and RH?
#13501466 - 11/17/10 11:58 PM (13 years, 3 months ago) |
|

Ok! I made a SGFC a few weeks ago, the holes where no 1/4 in but it worked fine. So........ I got another FC made, this time I used 1/4 in bit. Put in new perlite, now the RH WON'T STAY UP!
so I taped about 1/3 of the holes on all sides. The RH went up but not like it was with the smaller holes( it goes up does good than just starts to suck ass)
Should I cover more holes on the bottom and sides to see if that helps? Or should I go back to the small holes?( the reason I used the 1/4 in this time was cuz I found the bit and thats what the tek called for)
Please help!!
Ps: it's getting colder outside but there is a heater in the room

I have had the same problem. I just added a ton more perlite. That did the trick.

Blocking holes is not the solution, as this will hamper air flow which is critical for a SGFC to work.
Good luck!

I thought about that bit have only got enough for the other FC. Maybe I will add a little more to this one and tape like 1/2 the holes on the other one. Thanks for the tip!

The first one had like a million holes cuz they where smaller but I didn't redrill all of them. It worked fine with the smaller ones. How can I get it up if I can't tape some holes? It went up like 30% when I taped a few. Should I take the tape off????

I have not tried this so I don't know if it will work, but it sounds like it should:
Put like a box or something to take up a lot of space (volume) on the bottom and cover it with the perlite. This will be like adding more perlite. This will not hamper air flow and because of less free air space will raise the humidity.
P.S. Preferably something made of non rusting metal or plastic, not paper or wood.

I added more perlite and took the tape off. RH went up but it's not where I want it. Maybe I will add more perlite in a few days when I can get some. The only place that has it in by bags is almost $40.00 ( I don't thank so) Thanks for da help

What's your ambient rH like? I've been seeing a lot of Cool Mist Humidifiers on sale in my area, could you not just run one in your grow area? Evaporation of moisture from the sub by means of FAE is the number one pinning trigger which is why it's not recommended to tape/close off any holes in a 'properly constructed' SGFC. Keeping the rH up at the expense of FAE will only hinder your results, ime, and give you less than desirable fruits (skinny, small capped, co2 choked fruits.)

Yeah I put more perlite in the SG. The ARH is 38% outside , but is around 65% in the room. It's getting pretty cold here now. Could it be because the perlite is almost 4 wks old? The other SGFC I made is keeping a higher RH. When I first made it, it would stay 100% non-stop. There both 84-85% now. That's about as high as they get. Oh the ARH is around 60% in the room(a lil lower @ night Thanks for the reply

With ~40%+ ambient rH you should have no problem achieving the desired rH in a properly constructed SGFC, and by properly constructed I also mean the depth of perlite within. I manage to keep the rH in my SG at 95%+ with just 3.5" of perlite for at least 1 flush, this is with an ambient rH of ~40%.
Rehydrate the perlite, drain properly and check the rH in the FC again, or check/calibrate your hygrometer.
As far as temps and rH dipping slightly at night, thats not really a huge deal. Think about mushrooms growing in the wild, typically the temp drops up to 10-15f at night outside with the rH dropping a good 10-20% and mushrooms still thrive. If you're worried about excessive drying due to these dips then just compensate by a heavier mist before bed or something.

Ok thanks for the info. Maybe iam just tripping. I mist heavy before I go to bed I believe there's a lil more than 3 in in there. I have a cheap ele and an analog one. They both stay +\- 1% when I made the first one the RH stayed @ 100% but the holes where smaller. I will add more perlite Monday, maybe I will look into a cool mist or something similar. Someone said a reptile fogger, but haven't looked them up yet. Thanks for the time of the info.

Well then your holes are like 4 inches apart. Get out a tape measure and check what you've got going on. No way that thing is built to spec.

Simply build your terrarium per the tek and it will be right. I've used mine in less than 10% ambient humidity and it was still over 90% inside.
I suspect a crappy hygrometer, which is almost always the case. In addition, don't hang the hygrometer on the side of the terrarium, since the air entering the holes will skew the reading. Set the hygrometer on the perlite in the middle. If you've built the terrarium to spec, it will work, period.
Furthermore, humidity is not the number one issue. Fresh air is. Blocking holes destroys both. RR

Hi JD I guess the big bac was about right then. It was like a 16 cu ft?!! When I asked HD about it they said they didn't have it( found the small bag myself) I bet if I ask for thermorock they will know!! Thanks for the help inwill go there now and see if they have it!!!! If not I can order from there site. I will hit you up in a lil bit vea  Laterz

Hey RR, I did the SGFC per your TEK!!! ( thanks for the info on your site) I made the first one like 3 wks ago but I didn't have a 1/4 in drill so I used a smaller one. It worked great.
The problem didnt start till I got the SGFC and drilled them both with the 1/4 I got when I picked up a few things.
There is holes on all 6 sides~~ 2in apart There is only 4 in of perlite in them( that's all a $6.99 bag of 8 qt of per will fill them)
It maybe my hygrometer but I have two that are not the same( one analog one did) both from diff... Makers and suppilers. And they read about the same +- 1or 2%. I will go check out the perlite now and see what's up. Thanks for the help RR!!!
Oh and the RH in ther now says 99% buiuuuttttt?????????? ( it said 71% when I got up to mist fan and turn on the light at 6:30am

Toss the hygrometers out. They're crap anyway. Mist as required during fruiting. If the cakes and fruits are dry within half an hour after misting, then you have good air exchange and humidity. RR

What if it takes hours for the cakes to try up? Mine seem to only dry up when I wake up and they haven't been misted in like 8 hours and even still then my hygrometer is still moist. I fan the fg hard for about 30 seconds after I mist also

RR is spot on LL, as usual.
I was uncertain about SGFCs at first, as I had some trouble the first time around, and I live in a coastal desert.
This time I crowded 27 cakes into my SGFC and they are producing huge fruits.

To check thim you wrap a damp towl around them right? Well i did and they read 99%, put them in my bedroom 30% put them in my bathroom said 48% they where +/- 2% of each other. Maybe i will put them out side and see what they say. The RH outside is 46% now, or will that not tell me anything? The RH has gone up since I our more perlite?
IDK but really enjoy yalls opinions they help ALOT

Yeah I didnt have this problem until I re-drilled them with the 1/4 in The new one I made was per RR' vid. 2in apart( even made marks every 2in) I will kelp you posted if your into-it Thanks for the help JD

what he said
the idea of a shotgun is that air wics moisture up off the perlite to create a high humidity level, taping the holes makes that not happen, build it to spec, and if it still isnt working because your ambient rh is shit, your fucked unless you just start misting alot more, if you have the money, build a gh they are amazing in the winter, evantually youll upgrade to bulk and in alot of places low ambient rh in the winter time will be your worst enemy, forcing you to run something in your grow room which sucks balls

i also agree with your holes definitely not being two inches apart, maybe on the top but definitely not the sides. Also you should probably have around 5 inches of perlite, yours does not even look like 4. 6.99 is not expensive honestly but your could get a massive amount at a nursery probably more than you could ever use for cheap.

Not enough holes. In a SGFC, your humidity is created by airflow. So, you've got perlite, but not enough holes. You need air to enter the chamber in order to evaporate the water in the perlite, creating humidity.
Sure, the FC is smaller, but it doesn't dictate the spacing of the holes.

well i got a tape and looked at it it was off alil but i got a ruler and marked aver 2in
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . thats what every 2 in would be on the small side thats 30 holes(the way i did it, there where 34 holes) could that be why?
i did it like this
X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X
some thing like that(hope u can figer what i mean) i just made it fit the side
guess i will get a few more and try again. the first one i made did great but had a million hols bc i didnt have a 1/4in bit.
sorry for the rambling i will get off this post now and quite waiting ppls time:)

I don't even measure for the holes. I just wing it. As said earlier, stop obsessing over humidity. Fresh air is what you need, and lots of it.
