hi i have this very strong cabinet its 31 inches tall 16 1/2 inches deep 33 inches across i put my 600 watt hps light inthere but only have a fan with it n the temp is way to high i want to grow some lowryder but i will just end up cooking the planets so just wonderd what the best thing i could do to get the temp down or should i just buy a lower watt light and if so what watt light would i need to do 6 lowryder plants? any help would be appreciated thanx :-)

600w in a space that small
you could cook a chicken

you need to come down in wattage on your light big time and have decent ventilation

cooltube shade would b best takes the heat away from around the blub

try a cool tube ,otherwise a 400 watt or a few potatoes in oil

I swear by cool tubes for lowering the heat from lights (though I do wonder how many lumens are lost by the transfer through the glass), but in a space that small even a cooltube might not cut it. Quick rule of thumb is you want at least 30 watts of light per square ft of area you're going to put plants (50+ is ideal). you're currently at 200 (600/3) (I'm estimating the square footage as I'm in a lazy mode.) Likely with any HID light you'll need a cool tube, so buy one anyways. But I'd put decent odds that even with a cooltube, heat creap will be an issue in the box with anything larger than a 250W bulb. But I suppose it depends on the size of fan you're using to blow through the tube too. Which brings up another potential issue... if you use one system to both vent the room and cool the light you'd be forced to use a very low flow fan, which allows more heat to go through the glass (a 100 cubic meter/hr fan in your room would give you 6.5 air exchanges a minute. If you lost 50% of your airflow due to ducts and carbon filter, you'd still be looking at a complete air exchange in what, 18 seconds? Great for smell proofing the room, but that could be a bit too much air rushing past the plants (though that's a guess, I leave it to more experienced gardeners to debate on that, I think my highest air exchange rate was 1 a minute, and the plants were fine ) Just for curiousity's sake, please post your temps along the route you end up taking with light. I'm sure someone else will want to know sometime, and honestly, I want to know now (and don't you dare put a plant in there until the room temp is below 90 that might get you lynched here it's plant abuse )

would a 125 watt enviro light be enough to grow lowryder or would i need at least a 250?

a 125W envrio light would be enough to veg most plants if placed close enough (at least it worked well enough for a couple cloned hindu kush x skunks), but I'm not sure that would provide enough lumens to give a good flowering. Anyone know from experience? Admitedly switching to a 125W "flower" bulb would help a bit, but... I honestly don't know if it would give you anything more than popcorn nugs.

try a 250 watt bulb.{may be ok in 600watt ballast}

cool tube intake of air and ballast out of grow room+oscilating fan cool tube is like 120$ last time i looked .P

ok but i still wanna know if a 125 enviro light would grow lowryder ok as if i decide to do any other plants i will veg under the 125 light and the flower in a bigger space under my 600 watt hps light but for now i wanna try some lowryder in my small cabinet so will a 125 enviro light do??

really?
not something id fancy trying tbh, surely itd blow it?

check my diary ,the link at the bottom , i have a 250 in a cooltube and a couple of enviro's that i chop n change ,all in a small space

I have been using enviros for my last 3 grows. A 125 enviro will get you some buds on your lowryder but they will be tiddly! A 200 enviro would be 100% better - specially with a reflector. You could use the one you currently have. No separate ballast is needed.

Also - I strongly recommend that you get actual an 'Envirolite' bulb rather than a cheepo non branded bulb. In my experience, the Envirolites last twice as long but only cost a few quid more

ok i will get a 200 watt enviro light will i still need a cool aired reflector or would it be ok in my small cabinet??

A 200 enviro would be 100% better - specially with a reflector. You could use the one you currently have. No separate ballast is needed.?????

how would i use my 600 watt ballest with a 200 watt enviro light i thought that u could only use a certin light with a 600 watt ballest if i wrong could some1 please explain how it works and what the lowest watt bulb i could use with the 600 watt hps light i already have as i do wanna try and save as much money as i can on sorting this prob out.

atugwell mate, enviros have a built in ballast mate

kk im a noob sry
