    What is the hottest acceptable temperature for my grow space? I'm having a hard time keeping it below about 78 degrees and that's with only a 60w floro.

    When I get to the veg. stage, what are some cheap ways to promote ventillation once I begin using a mh or hps bulb?

    For a 1.5' by 2' by 5' grow space and only 4 plants, is a 400w mh or hps light overkill?

    You are going to have severe heat problems. There is no cheap/easy fix.

    To vent the small space properly you will need to do some carpentry. Use the same flex type hose and run that from your exhause fan outside.

    yea i just hooked up my 400w mh just to see how hot my room was gonna be and the light is real hot. im using a stare bathroom. Theres already an exhaust fan in there so im gonna get another fan to blow air into the room. Plus im gonna put some fans in that bitch too. and on top of that i set my timer to turn the lights off during the day, from 11am-5pm, during the hottest part of the day. but its gonna start to get real cold here so hopefully that will help too.

    Hottest acceptable temp should be around 90 - 95, 400w HID bulb it´s not an overkill u just need to vent it proper, i would go for the HPS its not as hot as the MH and puts out a few more lummens...u can use pc fans to extract the air or even kitchen type extractor fans (for a cheap solution), if u have the $$$ and have enough space u can go with a squirrel cage fan...also a oscilating fan inside the growroom will help to keeo the air circulating and stimulate plants

    I am trying to build a space that is about 3' hight and bout 2 feet wide. I wanna grow 1 plant just to play around. what wattage bulb should I use without having to worry about heat problems. I already have clones ready to flower (gift from friend). Unfortunately, I'm have to be as cheap as possible, although I do understand that I get what I pay for.

    Cheap would be Flouros 40 Watt Soft White Cfels

    Some money would be $120.00 for

    High Tech Garden Supply

    That setup. + more for accessories.

    You will be using a HPS light !

    You will be assuring that your temps dont get over 32° celcius....

    You'r grow room sounds ok ;)...... Is it 40cm x 60cm height: 150cm's ? If thats correct then yes go with a hps, guess there's loads of options. either u choose 2 hps lights.. 1 for veg and 1 for Flower....... or you can buy the Son-T Agro 400W Philips bulb & you will be happy with sprouting, veg, flower ;)

    Hope i could help ya ^^

    Dont forget to vent that room ;) I got my setup today... but i'm having little problems with the power....
