When to put the light on?
Panzora
started grow question 5y ago
Hey there, Do you need to put the light on the pots directly after you planted the seeds in the ground? Or do you need to wait untill they poke true the ground and then put the light on them?

Plant can't absorb light till leaves open. But I leave the lights on anyway because I don't mind paying my electricity bill.

Bulb or ballast?
Just checked my grow and noticed the light was ever so slightly flickering and also my tent was a few degrees colder..anyways I stayed and watched the light for maybe 40 mins and it would go off for 5 mins on for 10 and keeps doing it..

Short period grow
Hey fellow growers. So I have an odd question, Is it actually possible to start grow with 12/12 straight away? And how will it affect my plants? Let's say I have 3 autos and one photo. Will I have anything worth the time if I start straight with 12/12 light schedule? Thanks you

Idiot - new light, wrong sized grow tent
So I’m an idiot. All this time I thought I had and 80/80cm grow tent, when it turns out it’s actually 60/60, and I of course just ordered the SF2000 light, which is almost 65cms on one side. Should I just order a new tent right away to make it fit? Or could it be squeezed in? 😭

Led Grow lights
I have a viperspectra xs4000 light 480 watts I am running it at around 25% on the dimmer switch and my lights are about 24" from my canopy. I've noticed some of my pistols wilting and looking stressed. Should I try to move my lights higher or continue dimming them down more?

Shifting outdoor plants from outdoor to indoor
So I was wondering if outdoor plants(week 2) getting regular sunlight (~12-13 hours) can be shifted indoors for faster growing (18/6 or 24/0 or 20/4)? Anyone tried before? it is safe? Will it cause to make them hermaphrodite?

Small light/ big tent
I just upgraded tents. It’s a 4x4x7 foot tent. I have a Mars Hydro TS1000. I know that’s not enough for that tent. But I have a plant in its 2nd week of flower that out grew the last tent. Is it ok to just keep that light above that one plant in that size tent? Thanks!!

How much light does a seedling need?
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! Specifically this one https://www.gelighting.com/led-bulbs/e2624/ge-grow-balanced-spectrum-br30#
