View attachment 19518 I'll keep updating not overloading! Lmao /monthly_2014_12/image.jpg.f9fe61e4aed3de865515920766d0da1e.jpg
Just wondering if you keep your thermometer on the floor to record your temps. It's best to keep it right at or just above the tops of the plants. The temp on the floor can often be several degrees cooler than just a few feet higher up. Just something to think about! Be Cool, CG
Nice set up,...question.. on the the cool tube light exaust, i was not sure the set up on that, do you have a fan pushing the hot air from the light thur a vent hose out of the box? I know you said you had a fan pushing air thru and a fan sucking air from the light, didnt see or hear if you were using the hose.
No. No hose. I have the fan in the back sucking the air with a piece directing the the air away from the intake and ballast.
I'm sure he means the flexible duct. That tube probably uses 6". The duct can take the hot air either outside or maybe into another room to avoid recirculating it in the room and raising the room temp. The more air, and cooler air, you move thru the light the cooler it will stay. Good luck!! Be Cool, CG
Yes i was refering to air ducting. I think the glass takes away 10% of useable light so if you dont use the hose, you may consider taking the glass off like Res said. You can still use the reflector housing. Just a thought/option.
If you dont need the hose for the heat, consider taking the glass off to recoupe the light loss (about 10%). I double posted this because my last post got cut off, we must have been posting at same time. :thumbsup: Plants look good, they are going to love those pots, plenty of room to root.
View attachment 19519 So quick update all in the pic. Ballast running at 75%. 250w mh moved the back air flow a bit. I think it's set. /monthly_2014_12/image.jpg.31f2fd1906369bc48a1ceaf9dda0c051.jpg
Yeah I thought about taking the glass off but to lazy for that. lol nah just want to be able to not worry about burning them in the future. So it stays. :coolbounce:
You gotta get that light fired all the way up man. Slap your ducting on that light and blow the hot air off the bulb outta the closet.
:F-A-Qam man! i will explain only once more and more thorough! I have a six inch cool tube hanging as high as possible. In the front I have a 6inch fan blowing on the tube in the same direction as the back fan. In the back I have a 6 inch hole perfect withe cool tube. Outside of that I have fan sucking the air out of the cool tube. On the bottom I have a intake hole with a 6 inch fan blowing in.
If it works and doesnt burn the room down...:roffl: Just kidding, we all like to throw out suggestions to try to help our fellow growers out. If you dont mind. One other suggestion, you can lower that light down about 18" off the plants also. It wont burn the plants at that distance and will help fatten them up. If you switch to a bigger bulb/ballast during flower (do you plan too?) and heat does become an issue, i would consider the duct, and save on using all the light exaust fans except one if you use/have it as a inline fan.
To answer that is yes and no. I will switch to a 450 w bulb to flower. Not going to change my ballast because it can run both 250w or 450w bulbs. And yes good idea on moving the light down some but I do use shelf I made for this box move my ants up at times.
Oh and I don't mind. Love the suggestions. Keepem coming. I just post some quick replies. Not trying to be snotty or an ass or sound like one. Just busy time at work family time and you guys! Lol
