Hey everyone, just looking for advice and feedback on my grow room.
- Thread starter scmr420
- Start date
So now that i got the tent temperature and humidity where i want them,its effecting the veg portion of the room, grow has slowed since the humidity is no longer 70%. Im learning more about fim,and topping in this batch of veggies. Kinda wish i would have done a little more on the plants in the tent before putting them into flowering. Getting some yellowing of leaves on a few of the plants. I guess ill go threw my links iv saved on nute deficiency's,nute burn, and what not. heres a few pics of the veg half of this room.
The red solo cup is a seed i got out of a bag of master kush i had. Was excited to see it sprout.
Attutude seed status says dispatched, so we shall see if my 90 bucks delivers

Got my new ballast,hood & fan in today. As suggested i vented my exhaust outside,threw the floor and insulation facing the duct towards the siding. Tempatures dont seem to be as good as i expected from the new fan but im still running in safe ranges 75-83 depending on if i have the ac running on energy saver or just set to cool.
its 4am just checked the tent, the half of the room that im pulling cool air from is 70-75 but my temps in the tent are 79-80 on the thermometer i have on the ballast and 84.5 on the sensor i have at canopy level... I can put my hand on both the glass and the hood, its warm but not even uncomfortable to touch.i went outside and checked the duct, it blowing good, and i can feel good airflow going threw the duct on the back of the tent. Should i worry? Could my carbon filter be clogged, i just bought it?
here is a video of the new setup about 6 hours ago.

no ur carbon filter isnt clogged. it just seams that way becuz it pulls the air evenly thru the surface of the filter. it does cut down cfms a bit but keeps the smell away. the temps are acceptable.
altho i thing we had a mis understanding. i didnt know you were running ac in that room yet. i thought u were going to wait until summer. with the ac running you need a closed loop system for the light otherwise the fan sucks out all the cold air and your ac has to work harder to cool the space. a closed loop system is easy to install actually. problem being u will need another hole. the way you made it with the duct flange actually came out pretty good. looks perfect. gonna do that to a door with an 8 inch one i believe.
all you need to end the heat and close the system so the ac has time to build cold air in the room. take the filter off the other end of the light andrun ducting to another hole in the floor. it will pull the air from outside thru the ducting and the light then back outside. with no open sucking of air for the cold air in the room to escape. altho you may need to put a hold on the carbon filter and may need another inline fan to complete the project right. the second fan would be hooked to the top of the tent afterwards with the filter. so 2 total. one for the hood and one for the passive airflow for the tent. a good way to get by with what you have is to take the booster fans you had and use them for intake and exhaust till you can get another fan for the filter. also look on craigslist for inline fans in your area. might pick a 6 inch used one up for about 50 bucks. they normally have about a 10 year lifespan so even used you shouldnt have to worry about it dying for a good while.
in between 70-80 is best temp range. i flower right now at 85 but that just becuz i expanded and need to buy a big ass air conditioner now cuz my grow multiplied in size.
but even with 85 temps my buds are big and dense.

damn dude your shit actually looks really good. better than i had expected now that i get to see it. i thought it was all pieced together and ghetto. lol. but its actually looking really ballin for a person grow op. did you order a 400 cfm fan or am i incorrect. in all honesty it takes playing around with your setup to get it dialed in correctly. i can only toss out ideas that have worked for me in the past and could get you on the right track. also that filter if it is a cfm range of like 200 or so for the smaller fans wont work with the 6 inch 400 cfm one. they have to be compatible and close in cfm range. kinda matched up if you would say. also that 400 bulb being open could be a little extra heat in your room but shouldne ba anything to worry about.
this the the filter i purchase on ebay

states that it is
Maximum Airflow: 350 CFM
the inline is 440cfm heres the link for info

i would rather not have to put another hole in the floor for a closed loop system, plus live in texas. The heat here is retarded... During the dead heat of summer i have melted thermostats that are in my shed. 110f with the heat index and really high humidity most of the year. I just think that would be bad for the lights lifespan.
I definitely try to do anything i do the best i can, when i go outside and check the duct under the house its blowing warm air.
I am going to turn off the ac and monitor the heat in the tent today, if it gets out of control ill turn it on but i want to see where my peaks are right now. Outside temp is no higher than 80 right now but we haven't hit summer heat yet. right now my power bill is still under 250. Trying to keep it under 300 so i need to get it done now so i can minimize the use of the window unit.

o note, i only really have to worry for 4 hours. See im on a power plan that doesnt charge me for energy between 10pm-6am. the flowering tent light cycle is 6pm-6am, so for 4 hours i have to make sure the tent doesnt go over 85 and after 10 i can crank the ac down to 60 and get the tent easily to low to mid 70s. I know its not the most efficient but one day im going to build\buy a 10x10 mobile tuff shed and i dont want to butcher my house just to get a few yields under my belt.

yeah the filter isnt rated for the bigger fan. can still be put to use tho
also you also have to consider the surface temperature of the bulb. that bad boy is burning at close to if not more than 1000 degrees. that 115 degree air passing thru the hood is still going to be beneficial. plus you can actually just buy a hood for the 400 and have them both cooled by the same 6 inch fan and you could then use the boosters for you smelly tent and the veg for passive intakes/exhaust setup. in my honest opinion you may end up having to do it anyways. try it out for the time being and see how your setup goes. just tweak it a bit every now and then as need be and do homework on here.
thats actually pretty cool that you dont have to pay for most of the power.
I hope i can get a couple flowerings without having to change what i have just set up. i need to at least finish the 3 flowering plants first. Question my tent only has 2 exhaust ports at the top and one intake at the bottom with passive flaps i dont use... How am i going to run 2 ducts for a loop on the light and still be able to port into the duct for the carbon scrubber?

hmm. interesting enough the lower intake can be used for a passive scrubber. just run the ducting up to the top of the tent from the intake port and it will draw the air upwards from the passive flaps.
ok, if i run into trouble ill try that. I know the issues that are keeping me from doing what i need to do are light leaks. Cant really use the passive flaps because im doing veg and flowering in the same room. my ac leaks light threw the vents. Its just what i got to do to get by until i can buy a portable building. Its all a learning experience and i just want to get decent results until i can do it the right way.

understandable. no worries.
i didnt run the ac for almost 3 hours and by the time i turned it on the tent was 87-88. turned on the ac down to 65 and now my tent is 73. If i can pull a few decent yields with this set up ill will invest in a building and vent it with the lights i have. I dont know how these people keep their grow rooms with 1000w+ with no ac.

lots of passive airflow. also it helps if you live in a place that gets 90 at the hottest point in summer. the tent is at 73 after the ac kicks in? yeah you should be able to finish those three plants no problem. even with heat issues they will finish. im one of those 1000 watt passive guys now. lmao. but im getting a big ac none the less.
ya seems to be alright, may make it threw the rest of what i got growing before summer hit. Ya i understand all about the passive air flow once i get a building i will set up proper intake\exhaust. just not an option in my mobile home at the moment.Question how do you keep a ac running with all the passive air? isnt it just sucking out what you are cooling? like you suck hot air in, it doesnt even have time to full cool down before it gets sucked right back out?
