Light distance for Seedlings
Orion1522started grow question 4 years ago
My question is my 2 seeds have popped out and I am using 3- 8.5 watt 5000K LED lights to light them up. Both plants are under humidity domes so how far should I put the lights above them? I have them in a make shift grow tent for now as my regular tent is finishing up a grow.

Probably just above the top of your dome. That's not much and you want to keep them from stretching out too far. As long as it dont push to much heat 5 inches + 🤘😤

I would place them around 20-40cm depending on the seedling state/growing

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?

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.Other. General questions

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,

Sorry hat the question earlier before but I'm new here so I dont know how to undo the solved quesion status. The LED has about 300W and I want to dimm it. not simply turn it on/off. Preferably with some kind of integration in home automation systems like Home Assistant. Thanks :)
