This is my first grow. I'm using a 200w LED and have 10 ice non feminised seedlings. They are planted in soil, a mixture for herbs and tomatoes. All ten sprouted above the surface just over two weeks ago. They are all only about 2 inches high and have there first fan leaves between 1/2 and 1 1/2 inches with the second set coming out now. They are a nice fresh green towards the stem but are dark green for most of the leaf. They are looking healthy besides the colour. Soil ph seems fine, water every 3-4 days as soil on surface drys. I am not in any rush but this seems like slow growth and am open for tips to improve upon for my next run of seedlings. Is there any chance the LED is too strong for them. It is about 60-70cm away or about 25-30 inches.
