Hey guys, I've got a question on some of my seedlings. So far, I've got 9 sprouts going using 6 CFLs. I bought a 400w MH light for my veg. tent. The question is, how big should my seedlings be before I throw in the 400w? I've noticed my seedlings are really starting to stretch and those CFLs aren't enough lighting. Any advice is appreciated, thanks in advance.
On my current grow, as soon as they popped out of the rockwool cube I put her straight into the bubble bucket under my 400w MH. Granted, I had it dimmed to 50% the first week or so and then bumped it up. But I don't even think that was necessary. Like selassie said, as long as it's at a comfortable distance, i.e., it doesn't cook the seedling, you'll be fine. Just keep a thermo beside the seedling and monitor temps. But no problem putting a seedling straight under a 400w MH.
