How much light does a seedling need?
kevzzzstarted grow question 5 years ago
Is there a limit to what it can use? Could an LED grow bulb a couple inches away provide enough light? Up to what age? Thank you so so much. My first grow and I really appreciate it!

They don't need much! That should work fine for starting them in the seedling stage! Then ramp it up for Veg!! Cheers and happy growing!

thank you friends for all the help :) I should have mentioned the plants are destined for outdoor. The current ones I started got stretchy with a LED desk light (not sure wattage, not a bulb), so I'm going to try a mix of this bulb + outdoor sunshine and see how goes.

they need strong light fairly early or you will get weak, stertchy plants.
if it falls over and healthy otherwise, the light is too intense.
That light would be excellent for clones that need minimal light.. .but 16umol/s isn't going to grow much. MAybe directyl over 1 seedling with somethign reflecting light back in small area too? if it doesn't stretch, it is enough.

Remember that watts from the wall in terms of led lights = yield. The bigger the better! Just take into account the height you have to work with and then look for a lighting setup that will max what you can handle!

1 light or 2I have recently purchased a Mars hydro SP 3000. Great light.. It replaces my Blurple Mars hydro exo 120. I wanted to ask what peoples opinions are about me using both lights for veging. My grow space is not that big. 1.8m x 0.8m and 2.35m high. Will it be too much light and heat?Setup. Lighting

20hr light to 12/12Hey guys,
want to switch lights to 12/12 so can start getting the Gorilla Glue that never flowered going, the others still finishing up post flush and need to cut them early next week, will it seriously lesson the final crop of other girls to switch before?
