What's up GC. Ok so a bit about my setup. I'm using a gutted Ikea bed side table with (8) 2700k, 1600 Lumen CFLs running on two power strips. I have Mylar (technically its a thermal blanket) on the walls for reflection. I also have a 120 CFM fan mounted to the door (which is on the back of the table for stealth purposes) with a light dimmer to control the speed and an Ona container for smell control.You know how you read around the forums and they say not to underestimate a good ventilation system? Well they are right. All of them... Especially in a micro grow. This is my second run around at Micro grows. The first time ended about 2 weeks into flower with my crappy fan crapping out. It got up over125 degrees for 2 hours and completely cooked my plant. All because I didn't think through ventilation. Well to be honest, I didn't have one. I had a little fan blowing towards the door. (That I had to take off when the lights were on otherwise it would over heat, which is exactly what happened...)Ok so lesson learned. The hard way I suppose. But I'm not the type to give up that easily. So I ordered a 120cfm fan and mounted it as high on the door as I could, installed a floor (because there was no floor) an inch off the ground, and cut a hole in the back in the floor. That way when I put the door on, it would draw cool air from outside, up the hole in the floor and out the top with all the hot air from my lights. It also creates enough negative pressure to move the leaves and stems like a fan. I also had to light proof the fan while still allowing it to function. I struggled on how to make this happen for a while with different kinds of home made light traps, but was unhappy with the result. I ended up buying a dryer adapter from HD. I painted it black and mounted it on the outside of the door. Its perfect because it slides up and down so I can check the temp without even taking the door off while keeping the fan completely light tight. What I have now is so much better than what I originally started with. It is completely self sufficient. All I need to do is water her.I'm about 2 weeks into flower again and it is going marvelously in my opinion. I have yet to see any signs of nutrient deficiency or stress. I have been doing some pretty heavy LST and she seems to be loving it. I haven't given her any nutes yet, but have been thinking of doing so soon. Any ideas or comments are most definitely welcomed, seen as how you all are the ones who taught me how to do this.
Looking good bro what are your temps running? I just startd my mini fridge grow also im going to be using a bit less wattage in mine tho keep up the good work Sent from my SGH-T889 using Grasscity Forum mobile app
They range from 73-85 depending on the time of the day. I had to get a super powerful fan to do it though. How's the fridge coming along? Are you having temp issues too?
You should get either or both an intake fan and also a fan for inside to circulate air helps alot, an I did for a lil bit but I think I got it down now my temp ranges from 76-80 depending on time of day also but im only running 116w of light for now until I get my fan tht will go inside heres a pic of my fridge Sent from my SGH-T889 using Grasscity Forum mobile app
You know I had a circulation fan the first time around and it took up to much space, was inefficient, and didn't oscillate. And I've heard that if you dont get the strength of the intake fan compared to the exhaust fan just right that it can mess up your airflow. So I decided to go with a passive intake (no fan). The main fan is actually pulling air so strongly that it is moving the branches and leaves as if there is a fan in there. So I think I got lucky. And if I need to get the temp down all I do is open the window next to the box and it cools down to high 60s in less than 5 minutes. Your fridge looks awesome! You'll have more vertical space to work with than I do. I'm really interested to see how it comes out! Sent from my HTC6435LVW using Grasscity Forum mobile app

Yeah iv read what you are talking about but im gna try it out see hw it works ryt now temps seem to be ok but I am planning on adding bulbs that is y im going to also add the inside fan to circulate air and cool down bulbs but thats good seems like you have it under control as well keep it up bro! Thanks for the good complements man yeah I will be growing in it exactly how it is in the pic so I have 6" below the screen and 9" above to grow befor hitting the glass screen.

Sent from my HTC6435LVW using Grasscity Forum mobile app 15" !! That's more than the height of my who cab! I'm interested to see how The scrog works in such a small space. Got some updated pics. Her hairs are starting to turn to a beautiful amber color. Let me know what you guys think!
Haha yeah I can see that but it works well I seen it done plenty of times in PC grows and they harvest anywhere from a quad to a zip! Looking good man! Sent from my SGH-T889 using Grasscity Forum mobile app
Well thank you! She's 18 days into flower now, and I am starting to see nutrient deficiency in the lower leaves. They are starting to slightly yellow, so I think I'm gonna get a bottle of tiger bloom to help her out. She also isn't exploding in size like I was expecting her to. I'm wondering if maybe I trimmed off too many fan leaves or am LST'ing too hard. I'm also trying to keep it organic, so any ideas you all might have are definitely welcomed.
when would you put a plant into flower for a micro grow? i was gonna do it so see how it turned out but not sure when is a good time to push the 12/12 cycle? probably to early for this little one huh? View attachment 120045
