Well hello , i just recently set up a room thats 5' x 6' nd it seems to be perf for what i want to accomplish , i can fit 20 /2 Gallon pots in there nicely , and i 20/3 galllon pots later nicely to , but i was wondering if one 600w MH convertion bulb would be good for 20 plants in a 5 by 6 area , then ima switch to the 600w HPS bulb , ... u think it will be good enouph for the 20 so odd plants? , or would i be needing a 1000wer of both??
lemme know , thanks
Skyler:cool:
You should be ok with the 600w HPS, just be REALLY CAREFUL of the heat. The 600w HPS is gonna be around 90k lums, a 1000w HPS should be around 140k Lum's and more heat! Before dropping in around 20 plants in that area, i would get just a couple to grow in there so you dont loose your entire crop, just a suggestion tho. A trial run is always good for a new setup and keeping it small you can address any problems that may come up before it effects all of your plants.
Good luck on whatever you decide to do. :jointsmile:
ahh sounds good , :P but the basement is genuinly very cold in this crib , soo will the light heat things up that much with 2 fans in the room?
i dont know your basement, the best thing you can do is to run everything for a few days and see where your at. Take the temp and humidity with and without the fans on while your light is turned on. This will give you a baseling and you can go from there. It will basically tell you if you need more ventilation or if your ok.
well i have central air duct blowin Dirrectly in the room, and it blows cold :) unless the heat is on , an with winter ima keep it on 23 the whole winter , an all i got is a cheap fan on the floor blowing into a large tube that goes out the window ... but the whole room is air tight , sooo with a couple fans im hoping it will be good enouph
oh an im going to buy the 600w ballast and reflector with self cooling :p
It will heat up plenty, but you will want to run a small space heater in there during 'night' to avoid dewfall and a temp difference of more than 15 degrees.
I flower in the same sized space but run a K plus a 400 HPS in there. You really want a 1000 for that room, especially vegging under a 600 MH. I'd veg under a 400 with the plants all close together and then spread them out to fill the room and flower under a 1000. You want up to 3x the watts in flower that you had been using in veg to be most efficient.
ok then if i buy a 1000w ballast would it support a 400w bulb? , cuz i realy dont have the money or the time to get both ...?
???
??????
Usually not. You may find an exception on the net somewhere, but usually, a ballast rated for one wattage only uses a bulb of that same wattage. What you might do is get the 1000 and veg for a shorter time. I'd ALWAYS opt for the bigger light, myself, unless the space is so small heat becomes a problem.
Are you planning on the 600 because they're more efficient? If so, the difference isn't THAT great if your only running one light. Maybe stinky will pop back in here to comment on the shorter veg time with the 1000 idea. I'm learning the finer points of lighting myself---so I'm certainly no expert.
I have not heard of a 600w working in a 1000w, but that does not mean its not out there. You could actually get 2 600w HPS lights for your grow room, now that will mean more heat, but you will be around the 180k lums range and if you get a digital ballast it will help with the electric bill. What you really should do is figure out what your total electric bill will be while in the veg stage and then you will have an idea of what type of light you should use for flowering. The ideal thing to do with veg/flower lighting is to be 1/3 your light. So if your veg'n under a 400w you would want to have 1200w for flower. So, if you already have a 400w, you could simply go to a store and get some cfl's and then you wont have to worry about the 1000w. I'm not really sure on the difference detail on the difference between 400w and 1000w for flowering as far as bud performance, but it will be just fine for what i think you are trying to get.
No. It would blow that bulb.Quote:

Get the 600 or 1000 HPS and veg under a bunch of 4 foot shop lights. I'd get 4-6 2-bulb fixtures to cover a 4x4 area and cram all your little plants under there until they are about 10 inches tall and sexually mature. Then switch to the big HPS for flowering.
ya , im planning on getting about 10-20 46 watt CFL's the coil type i found 2 works nice for one plant :P , soooooo , after that i might just flower with a 600w , cuz Electricity bill is a problem , i will also be changing EVERY bulb in the house to a 12w cfl so the Bill will drop , and the HPS 600watter will make up for it... so hopefully it will work , any other suggestions....
ohhh an will a 600w be alright for a 5' x 6' White mylar room , with 20 or so plants veged to around 1 foot?? or alil less? ( i foot after tieing ofcourse because i like the way my plant had more bud site on it :p ) ...????lemme know
kinda crutal hehehe
Pce
Your still gonna want to watch that heat with the HPS. Just make sure you have enough vent for the heat. The best solution you could do would be to find a window, crack it, board it up, put a hole in the board big enough for a rat cage fan, then tie a tube to the fan that leads to a vent'd hood. The exhaust from the hood will go into your grow room, but the bulb will stay cool and the room should stay a nice temp. The only thing i dont know is what an outside of near 0F would do to an HPS bulb, but it should help with the heat alot. Then you can have an exhaust fan in your grow room that would go outside or where you want.
Hope that helps.
i have a window 1 foot in to the room which ima board up
are saying i should make air blow in instead of out?, cuz that would coool that shit down
but be stinky in the house?im toasted right now sorry lol , anywho im buying a self cooled light/reflector , ima look for the type an show u..600 Watt Power Plant Kit , is one .... an this ...NEW 400 watt METAL HALIDE GROW LIGHT w 400w MH LAMP hps - (eBay item 180157057307 end time Sep-30-07 18:30:00 PDT).... anyway .. bye
would a fan blowing directly on the light work?, cuz im to lazy for that shit :>)
You are planning on spending $$$ on a HID, setting up a large scale grow, etc etc, and are too lazy for something? Do you know what kind of work you are getting into? What is it that you don't want to do, the scrubber? It isn't that hard. No harder than setting up an external ballast HID and grow cab. And if you are going to all the trouble and expense, not having a good ventilation and scrubbing system is going to be devastating to your end result.Quote:

Check 2 posts up :p
no buddy's got noting eh :( , comeon people
a 600w would only cover a 3'x5' area by my calculations(during flowering) and that is lower at 40w per square foot. most want 50w or so. 40 works for me though. you want between 30w and 50w. so i am taking the economical approach and i dont have a co2 boost. in my opinion you could grow 15 plants under a 600 and they would be very crowded. if vegging you could fit alot more plants under the same mh but then you need a big enough hps to put them all under.
