The house is central ac,house is set at 72..usually stays around 71ish have a 6in carbon filter and 6in 442cfm fan in the tent exhausting hot air into the room, gonna exhaust it into the attic and see if can keep Temps a bit lower before I do put a window unit ac in the window (cheapest route) im sure with a window unit and exhausting into attic it'll be fine then
You really need to have fresh air coming in from outdoors no matter what the temp. That is unless you are supplementing enough C02 with a burner (counter productive to your heat issue) or a bottle. You need the fresh air intake so you at least have ambient levels of C02. Or your plants will grow slow and spindly. As far as a.c. units most growers just buy a small stand-up unit for a tent. Then you can literally dial in the temp and humidity you desire. They run about 500$ on average at home depot (14,000 btu). If you can't afford one 82 degrees won't kill your plants. Just not ideal. It is starting to cool down now that summer is over. You do need fresh air for C02 tho.
So, the ac vent that's comes into the floor of the room isn't bringing in enough fresh air? I figured it was enough if I exhaust the air from the tent into the attic, I mean being there's a window I can definitely plumb some fresh air in easily but did think id need to, and also, I know I can get a cheap window unit ac for 100-150 bucks.. Itll work just fine cooling the room down so it brings it more cold air right? Atleast that's what my plan had always been.. I could spend 350-500 on a stand up unit but didn't really want to guess I have a few things to think about glad I asked in the beginning
So you have a window unit in the room your tent is in? Then you have a blower from the room into the tent? Plus an additional exhaust fan vented to attic? If I got that right you should be fine but depending on where u live, u wont want to run ac 24/7 in the cool seasons. Right? Unless it was contained in your grow tent. No man, u got this!
LOL being in oklahoma ya during the hot seasons usually ac is on 24/7 anyway... It's like this, I have a spare bedroom.. 10x10x8...house is central ac/heat.. I threw a 5x5x7 grow tent in the room and it has a 630w cmh.. And a 6in carbon filter with 6in 442cfm fan inside the tent, duct work going out the top.. So it's exhausting the hot air into the bedroom.. And that's why my Temps are a bit warm I know.. But today I'm putting the exhaust duct work up thru the ceiling into the attic, so it doesn't exhaust into the room anymore... With the house central ac going the room is at 74ish(with hot tent air exhausting into room) ..tent is at 80..tent has a mesh filter screen at the bottom that I opened up, that's how the tent is getting fresh air....have a 5kbtu window unit that is going in the window to cool the room off more on hotter days (as temp outside is only 70s right now for a few days then back to 100s but not much longer) so Im sure once I exhaust the hot air into the attic my temps inside tent will lower because so will the rooms temp, and if that's not enough than I'm sure with the window unit on it'll def get where I want it to be... Again I appreciate the help man, even just talking to someone like this it gets all the shit out of my head I've been thinking about and able to discuss with someone like you, makes a big difference lol... Pretty happy with the way things are going after this convo today, can't wait to add 3 more tents.. 2 4x4x7 for flower and probablly a 2x4x4 or some shit like that for veg.. Eventually would like a perpetual grow
Ok I got u. Your right to vent to attic or crawl space. Hopefully you can figure out a way to pull fresh air in from ur window to that lower vent opening. Or at very least plumb your exhaust out, and place a small fan against lower tent vent pushing air from room into tent. (Just to help speed up in-flow) Just a thought. Your plants need at least 500ppm C02 to thrive. That's about the amount outside. Oxygen is more important to the roots. C02 is what your plants want.
Ya I'm positive with the window unit I can already think of a way to get fresh air in IF needed.. We will see, ordered a cheap co2 ppm glass tube meter thing from Amazon "Hydrofarm Active Air COTEST CO2 Tester Kit" to atleast be able to chdck... Didnt realize the meters are expensive lol
Yeah, the digital ppm meters are pretty spendy. Glad you found something cheaper you can check with. Hopefully measures in ppm. If ur close to 500 ppm u are golden. If it's a bit low the make these organic "myco bags" I think they are called. They are thick clear plastic bags packed full of mycelleum (mushroom root material). They have little vents in the top. They blow up and release C02. Never used myself, but i would think they would not make much difference unless you made your tent a sealed grow. Im sure you'll be in range. Hopefully. It will matter much more in flower.
First time a few mins then 20 mins.. Still nothing....gonna see what vivosun says... Modt likely will just return thru Amazon since it's new.. Then upgrade to nanolux.. Kinda just put me off about vivosun
Yup I knew all that... Made sure I had gloves on.. Even wiped the bulbs down with a super soft cloth I had for my car making sure nothing was on them.. Cuz it looked like their was fuzz on them.. So anyway, ya... Ill check fuse cuz I didn't do that thanks!
Good luck brother!
OH one question... The seedlings bring under a flourescent shop light.. Still 18/6?
Yes. It would work. It is your choice for vegetative growth. 18hrs on 6hrs off. A lot of growers will use 24 hrs of light during entire veg cycle. Some people say cannabis can't photosynthesize more than 18 hrs of light per 24 hr. period. If this is true 18-6 would be better to conserve electricity and equipment lifespan. Other growers swear 24 hrs grows cannabis faster tricking it into thinking it is one LONG day. I have used both photo cycles with success. I have been vegging 24 hrs of light lately mainly because of a new strain I'm working wich has very dense vegetation, and makes crazy preflowers at 18-6. So I switched to 24hrs, and that solved that problem. Hope any of that helped. Lol
Yup it helped lol... So get this tho.. I tried my light one more time when I got info off the ballast that support wanted.. Anyway.. Plug it in and both the bulbs fire up.. But looked like the cores were burnt black for the first like 20 secs while it was lighting up... And it took way longer for the bulbs to get to full brightness, much longer compared to the first time I turned it on.. Left it on for 45 mins to make sure the bulbs look OK.. They do, shut it off and let them cool down.. They look good.. But I'm convinced the ballast is fucked up somehow
Did u have to change the fuse? Or did it just magically work again after a timeout? What did tek support say? Either way im glad it ignited. Some electronic ballasts have a hard time with m.h. bulbs. Hordilux even makes a special m.h. bulb for electronic ballasts. It's working though. That's the most important thing here.
