Yes 55f is night temp. But it only dipped to that once because ccold night as heat upstairs waswnt on. Usually it only gets to 57f-59f or a little bit better.
HID lamps for seedlings?

Would 30-36 inches for my 1000w mh be overkill, I.e. harm my plants in any way? The temps shouldent go anything above 77ish for sure. I been having them under my 500watts for 5 dys, so I figure they can def handle it, right?

Exactly what I was thinking....

if u have other plants under your HID's then it isn't a waste of energy but if you're firing up all that wattage for your seedlings then it's wasted energy. also don't put seedlings under 400 or 600 watts right away. harden them off by gradually making them closer and giving them a longer duration. the key word being "gradual".

Just posting follow up pics of my seedlings grown under 1000w HID. I agree with the argument that it is cheaper to veg under another light source but in my belief it is a short term savings that is costly to the long term benefit of the plant. Have a great day everyone, Larry

The plants above ^^^^^ are @ 9 days from sprouting. Below are the same plants now @ 14days. I will continue to post for a couple of more weeks but using HID from the time it breaks ground gives your seed plants this kind of jump start. I will be topping these before the next photos as they are already at the 5th and 6th set of leaves. Happy Growing

Same plants 11 days later (over)ready for final transplant and another 2-3 weeks of veg. Happy Growing and don't forget to use your HID to give your seedlings this kind of start

I generally leave my seedlings under flourescent until the sucker leaves open up, 12-24 hrs after breaking soil then right into the MH.
Sometimes I will have a seedling slow to germ/break soil and the others are already in the MH. In that case, I go straight to the MH.
NOW, from time to time, I will have a seedling bleach and not like the MH at all. So yeah, I prefer to use the flourescent first.
