Blue Diesel week 1 pics 400MH

Heres some pics at 1 week under 400 watt mh an about 80watt of cfl

Sounds like a lot of light for that seedling.

I guess i shoulda mentioned its 4 plants haha they seem to be liking it tho

a little overkill but they will at least be use to the HPS and you wont need to harden off.

i had 6 plants to start with but 2 didnt sprout im mainly using the cfls to keep the plants from leanin in to the MH ill probably take them out when the plants r bigger

what do u mean by harden? this is my 1st grow using HID lights

anybody know what was ment by hardening??

Just most people start their seedlings off under low power CFL lights, as HID's can be quite powerful/hot for seedlings. Obviously when they move em to on to the HID light source it can be a bit of a shock for them as they are used to the less powerful/cooler CFL's so they need hardening off (introducing slowly) with the light source not too close. As you've started under a HID your seedlings should be used to the light and heat so they won't need hardening off
