How can I dim my grow light?

The way my room is set up I have to keep a 400W light about a foot or so above freshly rooted clones and they don't look happy about it. Can I plug the ballast into a dimmer or should I look for a screen to put over the light? Or do I need to change up my grow room?

2 options.

1. Dimmable ballast

2. Aircooled reflector.


I personally only use 200w CFL for cloning/veg time and hps aircooled for flowering.

My light is aircooled though not as effectively as it could be. Should I be able to put an aircooled 400w light a foot away from rooted clones without harming them?

Maybe I'm just lazy- but I'd probably just lift the light if its lumens thats bugging your clones.
If it's temperature then you need to think over your room temperatures- I have a 600w passively aircooled that hangs only ~6-8" above the canopy.. that said, those are hardened mature plants, but a 400w a bit higher shouldn't be a problem (aircooled that is).

But seriously.. you could buy things, make things, redesign things.. but if you're cooking your plants the easiest solution is to lift the light a bit.

I am with the CFL user. Use cfl or even fl for cloning and the first part of veg.
