This is my First ever Grow. I was wondering, how far from the seedling should my light be? I have bought a " Barrina L.E.D. Full spectrum 200W Grow light". It is Dimmable, and I have it set on 50% of its capacity, as it looks to be VERY bright on the new baby Leafs. Should I have it turned up All the way or? Thank you in advance for the help.

Without a light meter I would recommend 24” at 25% intensity. If the plant starts stretching lower the light or increase the intensity. Look into the smart phone app called PHOTONE, each growth stage has different lighting intensity and measured using PPFD/DLI. I set seedlings at a DLI of 18-20 and adjust this through the different growth stages

Welcome to the forum.
Light intensity is measured in PPFD (photosynthetic photon flux density.) There is a free phone app available to measure PPFD named Photone. Here are the minimum PPF guidelines by stage of growth:
Seedlings: 300 PPFD
Veg: 600
Flowering: 800
Measure the PPFD at the tips of the plant and adjust height as necessary to achieve the proper PPFD.

Welcome to the community. I have 2 680w lights that during the seedlings and early veg stage I have them turned to 25% and move to 50% in full veg and go full force in flower. Good luck with your grow. You can learn a lot here from these master growers. I’m a rookie myself 4th grow and ILGM

Good morning. Im not sure how to link it but, I typed in " barrina led grow light model inw556624650ac " and it took me to AMAZON web site and I found it there. Hope that helps. Scott

Avg hanging height for a light is 18-24 inches
You will wanna go 25-50% for seedling
50-75% for veg and 75-100% for flower.
You can also use a ppfd meter or an app like photone and use the described
Ppfd by @MidwestGuy above.

Good evening Sir…
Can I let some light hit my plants in the " VEG" state, during the dark hours? I see that I can not let ANY light hit my plants during the " Flowering Stage" as this will stop the Budding Process. Is this correct?
Thank you. Scott

Best to keep dark times dark and light times light.
Yes and no. 18/6 is considered veg lighting but 12/12 that is flowering light time. If you switch from 12/12 to something longer like 13/12 you could cause the plant to reveg. (This can be useful to do in some circumstances) light leaks during your dark times can stress a plant into hermaphritism. Reveg only applies to photoperiod plants, autos can be grown under 18/6 even 24 hour light.
At work we use green lighting to work on plants in the dark, it doesnt stress them apparently. Hallway lights are green also.

The LED density of most decent light sets are fairly constant.
If you don’t have a light meter and only for the time being, place the light at this height above the plants.
Seedling -24" from light
First half of growth phase - 17
Second half of growth phase - 12
Flowering - 15
Good luck. I just use my lux meter on my phone and then play “Kentucky windage” which means lux 8K-10K seedling, 15K-30K first half of veg, 30K-70K second half of veg and 50K flower.

Can I put small earth worms that I find outside, in my potting soil to help it?

I have heard mixed results from this. I would recommend using the worms you find to start a worm farm, a little research and a couple bucks you will have a sustainable source of both great microbes and bacterias as well as nutrients for many grows to come.

I toss a dozen nightcrawlers from the bait shop in my compost bin each year and they thrive. Im not sure they help it along nutritionally but biodiversity even at a macro/microscopic level is not a bad thing.
When I sift out my compost I have to remove hundereds of worms so clearly they multiply. They clealry inprove my decomposition rate where I lack building microbial heat.

Generally you’ll need to feed them leaves, our soil’s and pots are not ideal habitat and structure non clay like outdoors. Probably too wet then dry with frequent drowning on watering but it could be done if you read up about it.
Not recommended sorry, sounds cool, in practice bad probably cause worm stress and maybe death plus won’t add more than a spoonful of casts a week giving nothing to your soil
Imagine a race of stoned worms which after many generations saw you as god, that’s certainly one reason to try like imagine the day you showed them fire and shit… all chanting your name in Godly wormy hails wooowaaaawoooowaaaa hail the creator of fire.

Mine works fine enough. It really depends on the phone but its enough to get close. Light meters are not cheap. Some cost more then my light does.
