Lamp to Plant distance - Outdoor.

HappyLittleAxeDentsstarted grow question 3 years ago

If growing outside, what is the best way to calculate lamp (star) to plant distance for the journal each week based on time of year and rotation of our lovely planet? I am being facetious, of course! It's just a fun question for you all. Hope everyone out there good!

You would have to consider the earth rotation and axis alignment as well as you position to the equator. Also there’s the suns rotation around our galaxy and in turn our galaxies rotation around the universe itself and the gravitational pulls of each I turn pulling on each other at precise points in time and space! And don’t even get me started on the position in the celestial time space continuum factors you have to take into account... just grow indoors man, way easier! Lmao... cheers 💨

I think setting your room type to Outdoors would remove that question but I would guess approx 148,197,640 kilometers?

This question reminds me of the debate of light.. is it a ray or a wave? Haha science hasn’t proven one way or the either yet. But cool to think about the way sun light can travel so far and have so much energy left to grow a plant on earth.

Lighting cycle for VEG stage. Is 24x7 OK?Hi, Should I use the VEG lights 24x7 from the time I plant my seed until it's ready to bloom, or would something like 18 hours on and 6 hours off make more sense? Is there a "best practice" for veg lighting? It has worked for my first 3 grows. VIPARSPECTRA 600W LED Thanks, Mr.STM

Bad idea?Will a mars hydro TS1000 be too strong for a 60x60x140cm tent? I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.

Lights Hi guys! What light should I get? The viparspectra xs1000 or the marshydro ts1000? I intend to grow in a 2x2 space. Would the viparspectra be as bright as the marshydro because its more efficient?

Lux Meter and Hydroponics Who has experience with using LUX meters to position lights in various stages of hydroponic growth. I feel I am giving mine too much light, based on the readings, but don't want to pull them back. Currently 10" from the plants.

Light penetration for inner defoliation?? Outdo High, y’all. This is Dark Star from T.H. Seeds. She’s a broad-leaved Indica 3 weeks into flower. Looking up into my plant I’m getting 15% light pen or so. Should I be shooting for a certain percentage or perhaps clean out a majority of the inner veg? 2nd year (legal) grower.
