I have some seedlings that just emerged last night and are ready for some light. My T5 that i got from HTG Supply (that is only 5months old) has pooped out on me. I usually veg my clones and seedling under this, now that it is out do you think it would be ok to put them under a 400 MH?! I really dont want to kill these guys because there basically all i have left, from an incident.

So can this be done harm free?

Yeah I do it all the time. Start with the light 18-24 inches above the canopy.

Keep it up really high to begin with and you should be fine. T5's throw a ton of light for fluoros and the transition to MH shouldn't be that big of a deal. They may shock initially but not for long and a 400 watt MH should really produce great veg results.

I would put the light 3 feet above the seedlings at first just to make sure you don't fry them. You'll get good light coverage this way, if you have lots of seedlings growing. In a week or two after they start growing and doing their thing you can adjust the light up or down as needed.

Thanks for the speedy reply everyone! I'm gonna setup the 400mh in the room and take a few pics. I know its probably gonna be alot more heat in the room than usual but it'll have to do until i can get that T5 replaced.

Once again thanks all!

as above,
should be np's as long as you keep the light/s up at the mo and progressivley lower as time passes.
