cfl 125w or 250w 60cmx60cm tent for autos?

Have 2 autos (hbd) in a 60cm x 60cm x 140cm tent under 125w clf in reflector. Currently in veg with blue spec bulb, but expecting to state flowering in next week. Planning on buying a red spec bulb and cable and adding to tent with blue spec. Unsure whether to get a 125w or 250w bulb. Only small space, so will 125w and 250w be too much heat / light? Any advice?

I plan on getting same size tent with 400w hps 4x plants. U will need some cooling though. I have 250w cfl in veg room.

Sounds like I'll be fine adding another 250w cfl. What extractor fan you using? Most on market seem like overkill for such small tent. Be adding couple more next grow

After much debate and thought will be high velocity 5" fan and filter combo. Think 340 m3/hour. If I was you your not benefitting really from having 2 lights. Just upgrade to 1 bigger light. Either cfl or hps. Because its a small 0.6x0.6 you not got much square footage to cover IMO.
