Just wondering a rough range when seedlings can take 1000w. i currently have em under 400 the light is a few feet up. i can do around 3 feet on my 1000w with flood table. id think after the third or fourth node....what you think?
 
when they are SEEDLINGS!!! LMAO but for real, just keep the light up high ....
 
hmm, ive found that its the heat, not the light amount.

have started seedlings 1 foot away from a 600. (they need to more or less start under the light (as soon as possible after sprouting)its only when they´ve allready adjusted to a weaker light when you need to keep the lights far away)

id watch it though the first day :) but the biggest threat is drying out the seedlings, not light burn.
 
haha i would never.

yeah i mean alot of heat is bad for them, they would die from far less heat than a vegging plant for example. but keep the light up high. like a few ft. and slowly take it down.
 
It seems like using a 1000 watt for seedlings is overkill and a waste of power IMO... do you have a dimmable ballast? For seedlings you should use a couple of T5 HO tubes.. much less heat to worry about and you wont fry the seedlings.
 
Thats like saying how old does a plant have to be to take the sun....
The moment they sprout.....but you dont really.need to use the 1000 if you have a four hundred..id veg under the four and flower under the thousand...save electricity
