600 watt metal halide for newly germinated seeds?

[Noonin NorCal]

Hi people i was wondering if a 600 watt MH would be to intense for seeds. We germinated seeds in water and just threw them in 3.5 inch plastic containers. We have a closet in the flowering room with a T-5 and a bottom heat pad set up already but are having heat issues with the room, plus we might have some light leak issues if we fired up the T-5. The 600 watt MH closet has clones already in there and there is room, could we put them in there without bottom heat? Is a heat pad really necessary? Thanks

Im not using a heat pad on my clones or seedlings right now. In the winter maybe. Not needed now. You can use a 600w, how far is it away? I would lower it over the course of a few days to a week if possible and see how they respond watching for bleaching but it should be ok.

Why are you concerned about light leaks? From outside or inside going outside?

How hot is your veg?

The 600 W MH light is on the ceiling as high as it can go so probably 8 feet or so. I have a bedroom thats flowering 4 weeks in and there is a closet in the room that is set up with a T-5 and a heat mat. I was worrying about that light leaking to the main room. I have a black/white tarp would work for the leak if there was any. Plus we have only so much power we can run from that room, we could probably get away with using half the lights on the T-5. The veg. closet is in my garage, it does stay nice and warm. its probably low to mid 80's during the warmest part of the day. If i put them in the 600 Watt room they would not be directly under the light, its a pretty small room though. Thanks for the quick response Tess

Thats far enough away. It might even be too far. If they start to stretch too much lower it with chains (2x4 drilled into studs with I hooks)

I was going to say, any leaks, panda paper it up.

I wouldnt start tripping on veg heat until 85.

Looks like for now ill just put them in the 600 Watt room, I'm just gonna raise them with a 5 gallon bucket. Thanks for your help Tess

I have a station set up for autoflowers. It uses the same bulb from seedling to harvest and the seedling flourish.

The bulb is a 600 watt Solis Tek at 10,000K. This duplicates the sun with a 96% color rendering index including UVB.

Using the same bulb start to finish allows the plant continuous growth without the need to refurbish the chloroplast distribution because of frequency changes in the light source.
Fresh popped seeds are kept at 50" and moved up as they grow, harvest distance is 18". With 18 hours of light less intensity is needed to reach 100% of the Daily Light Integral.

In the past 4000K CMH was used but technology does not stop and this Solis Tek bulb is the latest improvement.

I am not really adding much to what tessarecting said, just mentioning the benefit of using the same light throughout the entire grow, any quality full spectrum will do the job.
The output of the top full spectrum brands has got to the point where the differences are close to the margin of error in the testing.
