i got a 400 watt HPS bulb will this work for about 2 plants?

[Gorecore]

Yes. You should be able to grow about 6 plants with that much light.

[Psyclone]

Yes but you can't put it into a regular light bulb socket in your house...you'll need to buy a ballast. You can get kits from ebay to sun micro online stores.

o really that sucks I dont know if I want to deal with a ballast. What is a good light bulb that I can use with a regular house socket that will grow 2-4 plants?

[Psyclone]

Compact fluorescents are your best bet.

i was reading that the cheaper low wattage bulbs give you taller, skinnier plants with a smaller yield than if you used a HPS bulb. I want the most I can get since I will only have a couple plants. Should I get a ballast and deal with all that?

[danthebadman]

i would stick with the hps and get a ballast...im running a 400watter right now and they look amazing but i did spend near 1500 uk pounds on my set up

[jbomb269]

i will be using the 400 hps with ballast i was just wondering if it makes any noise because this setup must be quite lol


also can I run 3 computer fans on 1 9v adapter wired up?

the ballast should make no noise what so ever

and 3 cpu fans for what? intake or extraction?

intake (sucking air in to your grow space) yes you could use them but maybe more than just 3

for extraction i would not bother

[jbomb269]

ya there for extraction the area is only 3by3

[jbomb269]

also if i have a socket that can hold a 250 watt bulb does that mean that it can use a 250 watt HPS bulb with no ballast or do I still need the ballast?
