How far should my Spider Farmer SF1000 be from my plant

Hi ILGM community,

I’m fairly new here and I posted my fist topic about lighting a few weeks ago. After many members helped me pick out my first light for my one plant. I went with the Spider SF1000. It came in today and I installed it. I don’t have a lot of space so here is my current set up.

My question is about distance. How many inches away should the light be? Also, the light has a percentage. How high should I set the the lighting? Max at all times or lower like 50 percent?

Thank you for all the help!

Here is their chart which should give you a starting point.

From there you’ll want to keep an eye on your plant. If it is stretching, lower the light height a bit. If nodes are very close and you want some more stretch you can raise it.

Technically you could also go lower height and lower intensity to help control temp in the tent but that light really doesn’t throw much heat regardless.

Hope this helps!


@Mm2021, first of welcome to the community and to the forum. Nice choice, cool space, seedlings, to cuttings, 12-24 inches for new growth. See pic! Reviving plants for my friends, and big 1 Super Lemon Mac is my bad, gave her wrong bottle of feed, is what I guessing. Since I have so much going on, 2 tents, dwc, clones, thank god, I not doing an outdoor, I’d be in trouble. Hope this helps you with your grow, happy growing

Thank you @CygnusX1, @OldSkool and @MeEasy for the information. It really helps to get a visual. I may only have about 22-25 inches to spare.
