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.

amount of sunshine for autos in late flower - open air, outdoor grow
We're getting 14-15 hours of strong sunshine a day. Now that I'm late flower, should I move my autos into a spot that will get shade for half of the day? Seems like they may not need to be pounded by this much light/heat at this point and could use more down time.

3000 watt power use
This is my first time using such a powerful light in my opinion, 3000 watts seems overkill but that's what i want. The question IS, is it better to have 1-2 plants under the 3000 watt or worth it to manage 4 at a higher distance? Cheers. Don't keep techniques in mind.

Light spectrum during veg and bloom periods
I have 2 1000w full spectrum lights. Each light has 2 switches-a veg button and a bloom button. This gives 3 settings for the lights-veg only, bloom only and both lights on at the same time. What settings should I use during Veg and during flower and how close should I hang them?

Posible quemadura?
Cada vez que entro en floración me pasa esto y no encuentro solución. Uso una tienda de 1,20 x 1,20 y tengo un led de 730w empiezo a pensar que la luz es demasiado potente y las plantas sufren de calor. Hubo dos dias en los que llegó a 32 grados actualmente estoy en 29/30

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?

Spider Farmer SF1000 or Mars Hydro TS1000?
What would you recommend between Spider SF1000 or Mars Hydro TS1000? Both seems pretty similar, which one to chose? I’m planning on growing two autos at a time/or one photo, 70x70cm space.

For folks with Mars Hydro TSW 2000 experience. What dim did/are you keeping your light on during weeks 2-3? I have done research and looked at MH data, but I would like tried and true experiences. Current dim is set to 2 notches below 50 at 18in. Thanks.

My Timer malfuntioned and gave them over 22 hrs of light?I was wondering why they kept growing this fast and big until i controlled the system and noticed they get to much light and stretching this hard. So i turned the hrs down to 16 to stress them into blooming, will this Work?

Heyho So apparently my plant got bigger than I thought. After stretching its only 30 cm from the Mars TS 1000 (Its already on the highest possible position) And I'm running it at ~80% Do you think I can turn it up to 100%?

Light distance and when to top?
I'm using a 300W LED. What distance should I keep the lights at now that I've transplanted and the plants are doing well? I'm thinking 24" and then move up as they grow until flipping. Also, when should I top? I've read that waiting for 6-8 nodes is the right way to go.

78,600 lumens at canopy, ok for pre-flower and flowering?
I have recently received a lumen meter. Measuring 78,600 lumen over canopy, is that OK? For my other grow, does anyone know how many lumens seedlings need (at about 25000 now) ? I can convert from PPFD or PAR. Educate me! Thanks

If humans took weed to grow on another planet where the sun was up for 28 hours and down for 10 hours, how well would it grow? Would the plants adapt to the different light / dark times? Or maybe 24 of hours light, 6 hours of dark? Theories? Earthly Proof? Comments? 👽
