5 x 5 ... what to use?

[nadvida2007]

I'm planning to get two 400 watts HPS with bat wings reflectors and place them at about the midline of the square ceiling.... What do u think? I'm trying to flower maybe 20 plants in this 25 sq ft room. will heat be an issue?

(2)400's is a touch low, at just 32 watts per square foot, if you intend to fill the whole space. Up closer to 50/ft is better.

How tall is the space? Heat could be an issue for sure, and good ventilation is key.

20 plants with a 400 watt hps is a bit much. I would get a 1000 watt system with a vented hood so you wount have any heat problems.

5x5 i'd go with 2 600w. Thats a lot of square footage. Depends on height too i suppose.

You can find 600w for $100 online, look at Urdedpals posts, he put it on here some where.
