Both of those questions are kind of difficult to answer. The short answer for watering frequency, would be to not let them get too dry nor too wet. If you are trying to germinate seeds, don't let the surface of your soil dry out before they have sprouted and developed some roots. When I start seeds, I lightly mist the surface of the soil several times a day until the seedlings are germinated and well established and after that, I just go by hefting the pots. If they start feeling a little too light, I'll add some water.Thank you very much, Bob!
Was curious how often do I water seedlings in seed tray and how low/close should I hang the grow light to the tray?
As to the light distancing, this could vary wildly according to the intensity (Lumens output) of your particular type of light. Hold the back of your hand under the light, determine the distance that feels uncomfortable to your skin and keep your plants a little further than that distance from the light. I have two different LED lights in two separate cabinets, one of the lights puts out 10,000 plus lumens, the other puts out 15,000 plus lumens. The top of my pots are about 13 inches from the light.
Not trying to be critical, but it looks to me as though a lot of your light is being wasted by just going out into space. You really should have your light inside a cabinet with the walls and ceiling painted flat white, so that most of the light is reflected back onto the plants. Don't use glossy paint, it can create hot spots, the flat paint reflects light more evenly. If it gets too hot in the cab, cut a hole in the top and mount a computer type fan to exhaust the heat.
Good luck, hope this helps.
