When to put the light on?
Panzora
started grow question 4y 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.

Increase light hours autoflower
My autoflowers are 6 weeks old and showing flowering signs. Can I increase the number of light hours from 17hrs to 20/22/24hrs? Does it cause light stress and can trigger vegetation or make it hermaphrodite?

Tent too hot?
I added two blurple lights - I'm not sure how much they're helping growth but they are definitely making the tent hotter - about 5 degrees F. I have a fan blowing at the bottom of the tent and at top over the lights but I'm worried that it might be too hot. Should I ditch them?

Diferencia en el color verde de las hojas
Estas plantas automáticas están recibiendo la misma alimentación, agua, etc y están en el mismo tipo de sustrato. Pero unas (las más oscuras) reciben luz artificial adicional (Neón CFL) para llegar a tener 17h de luz al día. ¿Es normal la diferencia? ¿Cuál se ve mejor?

300w COB CREE Distance?
I've put my 6 seedlings under a 300W COB CREE UFO light, atm is a 30cm distance from them, I do hope is not too close. I've only a 140cm height and more would be problematic to manage in the long period.

From 24h to 18/6h during flowering ok (autoflower)?
Royal AK47 Autoflower: Changing from a 24h light cycle (since beginning) to 18/6h when already flowering - no problem or not recommended? The temp is a bit too high (~30*C) I think.

Different lights
Hello people, hope you all doing fine. So, I have 3 different light models, I´ve been using them individually for plants. I use only autos and adjust the light distance individually. Should I place all the lights in the roof togheter so all plants get the same amount of light?

Lightning question
Hey, Growers! This week I had to open together the two boxes, so now all the plants have both kind of lights. Do you think, it can have a negative effect on them, or maybe it's good at least for the 140cm height White Widow,because the bottom parts get some more light from there?
