These seedlings are two weeks old today. They've been under a 2' t5. Are they ready to switch to 400w metal halide? Would they grow faster or would I be wasting electricity? image.jpeg image.jpeg image.jpeg image.jpeg

I'm just wondering if they have enough roots/ leaf sets to absorb all that light. I'd rather not waste electricity by switching until they're ready

I ran my MH on 18/6 at 3 feet away, as I have a small tent that picks up a lot of heat. Also ran it on 75% with my ballast. Switched to HPS bulb a few weeks later. Still @ 75% to avoid heat issues. 2 1/2 feet away

Growth is very good

They plants need as much light as u can afford to give them. You can even go 24/0 if you like.

I started my seeds under 600 mh 24 hours on. Just not too close. They sprung up like crazy and it was an amazing experience
