Well this is my first grow. This is using CFL's in a growbox.

4 23w Daylight CFL's Veg
2 40w SoftWhite Flowering.

Temps are still high even with the addition of a 80cfm fan, temps peak at 95F Low at night is 75.

Just thought i'd start a journal as suggested by other members.

Simple Rubbermaid 36L clamshell.

All links say error but they all work.

Nice! doesnt look like temps affecting much, my temp peaks at about 95 too and my plants look really healthy, but try to put some c02 in there so they can breathe(Home Made Co2 Tutorial) takes less than 2 min

Thanks for looking Coolman.

Been using CO2 the whole time So temps havn't been that bad. A 1L warm water 1 tablespoon of Yiest, and 1cup of Sugar last almost 2 weeks with daily to 2 day shakes. Since i upgraded my box i've been having higher temp problems than in my small enclosure. But just added plexglass last night to seperate the lights from the plants, intake/output in the area, and fresh air coming in from the bottom.

Carbon filter is still a concern of mine though, i made one about 2" thick 4" wide tube. Packed with ground up activated carbon for fishtanks. Works decently, but is impeading airflow raising temps. I just took it out and last i checked temp was at steady 87F, before around 93-94F

Will update later tonight with new pictures from day 8 flower.

Just wanted to add from my observations, growth all but slows to a stop after temps go above 95 for extended periods, i havn't seen much if any heavy growth above 95F, between 85-95 its fairly nice. Havn't been able to get below 85 for even a minute with lights on, night temps last night dipped down to 66F, which is a first. Temps have been 75 nightly, and 90-95 daily. I hope to get them to 85 if possible, though the higher temps are working to my advantage some, giving me longer to grow them, allowing myself to be out of town hopefully for a full week.

Wait so what exactly are you usin as a setup, im using 2 rubbermaid tubs do you think plexiglass can work me if i put it on the to where the lights are? I havent cheked the temp on mine yet since i put in 3 frozen water bottles by 1 intake fan, hopefully itll be at most 92. Where did you get this plexiglass? do they have it at walmart? Cus its a good idea to separat the growing area from the lights area and now you got me interested

Well after 3hrs of no checking and leaving it at ambient temp. Its at a consistant 89F. Which is liveable, and will do for now. I took the filter off and temps easily dropped 4-5F since. So the filter was impeading airflow heavily.

As far as does the plexi help, hell yea. I have a little peep window up top, inside the plexi area and its warm, you can feel it on your face when you look in, otherwise inside the plant chamber its at 89F. I'm going to look for another thermometer to compare temps in both areas. But i definently think its worth it, keep the hot air up high, and away from the plants......large outputs pulling air across the lights and out. Definently works...

Will follow up later with pics.

Thanks, where did you get this plexiglass or where can i find it and how much is it?

The plexi i got was at Lowes, look in the acrylic and sign area. It was 1/8" at 3ft x2ft and was $6.

Temp is still at 89. This is almost perfect. Next i need to incorporate the filter and keep the temp at the same place......thtas the difficulty.

Todays update with pictures added.

This is the bottom half of my clamshell type box. There propped up on a 2" cinderblock for weighted bottom, as well as a pair of 6" deep cardboard boxes.

Seen next is the Lights, 4 26w daylights (blue) on the outside, soft white 40w Reds on the inside. On the right is the output Duct fan, on the left is the pushing 80mm cpu fan. Plexi is 6" from the roof.

I'm going to need to start training the heads here soon. There getting longer than i had anticipated, probobly because of the distance away from the lights, but its all i can do to keep temps down. what can i do for the heads themselves?

i know you've had problems cooling and im having the same, but check out the huge vent i got for my rubbermaids at my grow haha, its pretty intense :P
