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.

Can too much light in Veg cause EC to skyrocket?
Hello everyone, I have 4 plants in a 3x3 area under three of these lights - https://amzn.to/2MhseVH 360w all together which is what I expected to use during flower, I didnt realise that you dont need to use as much during veg, all plants have had to be flushed with EC's at 10

Hans panel 180 use veg mode or not
I've got a hans panel, it's got veg setting and flower. i had it all day on veg mode, seedling was stretching so i placed maybe 30cm from the lamp, but now leaves turned bit yellow. Would it be better to put it on flower mode and place the seedling further away?

Thoughts, good idea or bad idea?
I got an idea from when I was pruning pecan trees growing up. If I install small LED lights directly inside each "window" or "pocket" will that improve total light and production, or will I just burn the plants?

Do you lower light intensity and temps towards the end of flower?
So I’m in mid flower, start of week 7 to be exact. I’m curious on when you guys start pulling back light intensity and going with a little cooler temps. I’m running a 240W S33 from AC infinity in a 3x3. Should I be going strictly off of PAR or VPD at this point.

Does it make sense to buy another Viperspectra xs1500 with 150watts? So my question is, if the power of 2 same led lamps add up together?

Led on 18/6 grow/flower photoperiod
I have the idea to put a led in my second tent for pre growing photoperiod girls, I have some room left over for some autoflowers who also grow & flower on 18/6 light - leds can switch between grow/flower. If I switch the led to flower will that be OK for my photoperiod girls?
