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.

600w hps
Wouldnt let me PM. I have a 5ft long 3ft wide 6ft tall white walled grow room and am thinking about a 600w HPS light now. Will this fill the entire room? If so how many plants should I plant? Will this one suffice? Would a 400w hps be more suitable for this space?

12.0v LED strip effectiveness
Will this mini led strip help my other weak light out? Or is it wasted energy. I’m still putting the plant in the sun as soon as it gets onto my balcony but while it’s really cloudy and in the evening this is all I’ve got.

Light set up.
My only question i have is about my light set up. My plants are 7 days today and i noticed that my plants are all facing towards the light. I have my light at 60cm from the top of the plants and 75% on the dimmer. The light is also 1000 Watts. The tent size is 4x4.

Hello fellow growers :D thx a lot Firstly, is the reason why my plants (especially cookies) are very slightly curling/folding at the ends of the leaves because the LED is too powerful?(Reason to be worried?) Secondly, should I start adding nutrients? Just 1/4 of Bio-grow for now?

Just ordered a 150W Quantum Board, can I swap my Blurple UFO mid grow to the new board? Is it possible to increase flower size this late into a grow?
My Blurple apparently uses 230W actual draw but is advertised as 600W. If that 230W value is correct, does that suggest my new, much more expensive QB is not as good? Will it make a difference to the plants health? What are the benefits from the QB? Thanks!

Did I start LST too early?
At day 22, did I start LST too early? I feel that I may have stunted the growth a little from overheating, but didn't want to wait too long to start training. Also, would a higher-powered light cause less distance between the nodes, and therefore make LST harder/less effective?
