Do seedlings need a certain amount of light? And what does my ph levels need to be? I just germinated them and put them in the soil.
And how can I prevent stretching?
well you can prevent stretching by keeping the light close to the top of the plant if your using cfls keep the light about 1.5-3 inches away from the top of the plant. put your hand under to test the heat if its too hot for your hand your going to burn your plants if its just rather warm your safe to go.
