Looking to buy an HPS system, need advice

Hey I am thinking about buying an hps system but am not totally sure which one would be the best fit for my plants.

Would a 400 watt system be sufficient for 4-8 plants? So far I am considering Hydroempire, Organic Hydroponic Nutrients, Indoor Grow Lights and Supplies - 400 Watt HPS & MH Advantage Mini System - $279.95$239.95 or finding one on ebay.

I would like to keep the price as low as possible but the idea of getting a system that would be able to use an hps or mh bulb is pretty attractive.

Any suggestions?

It'll be pretty tough to fit 8 full-sized plants under a single 400w system, and you'll most likely end up with some pretty wispy buds from the plants on the edge of the light footprint. A 600w-1000w would be more efficient for normal sized plants. (2-4 feet) If plants are kept short and the canopy even, like with a SOG, it'll be much easier to make the best use of a 400w light. Just remember to keeping things properly ventilated and under 80 degrees Fahrenheit.

Also, I haven't been to the site in a while, but I've found some really good lighting deals from a site called "Discount-Hydroponics". May be worth looking into. And don't forget to check places like eBay, Craig's List, etc., for great deals on used/new systems.

thanks for the reply, i will probably scale down the number of plants i have to fit within a 400 watt systems abilities since getting anything larger would add more heat to the room i am growing in. It would also be more expensive, I would like to save money if possible but understand the difference in using an hps and not when it comes to better yields.

Anyone else have any suggestions on what i should look for in a 400 watt system or maybe a good source to look for one? What features are important to have? I know air cooled systems are much better but honestly i can't see myself getting a ventilation system with tubing.

check out hydroponics.net theyre a good source for equipment like that

Ive used HTG Supply's lighting products bought off ebay, and have always been very satisfied with the item, shipping, cost, and quality I have received.

Nothing but good things to say about them.

i second HTG. I bought a 600 from them, they did not have the bulb i ordered so they sent me a different one for free and then sent me the back ordered one as well.

I third HTG I bought a 400w hps from them and a T5 for veg very pleased with both and the cheapest prices!:rasta:

I like Discount Hydroponics. I got a 400 watt system from them that has a switchable ballast (MH/HPS). It was $130, included ballast, bulb, light socket, reflector etc. I like it because you can switch from veg to bloom. Great for a 1 light system. I looked 4 years for a better deal, didn't find one. Good luck. When you call them 1-877-476-9487 tell them you are interested in economy price and they will greatly cut their web prices. At least it worked for me.

chenman. You might look into getting a motorized system. Can cover more planys that way.

a motorized system would be a bit outside my price range at this time but i agree i light mover would be great to have.

lolagal, what does the economy price include? Do they cut prices by cutting the quality of the equipment?
