Rangaku
started grow question 3y ago
Has anyone ever moved a plant from HID lights to LED during flower ? Keen to hear from your experience as it’s looking likely that I’ll need to do exactly that in the near future .

Yes it can be done. A lot of times you may need to add a little more cal mag is about only issue. Plus Temps won't be as strong. Good luck. 🌱🌱🌱

Yellowing leaves & tips curling down on 14th day. Coco / Autopot / Hesi / Mars Hydro fc-1500
Would gladly use some help with my first grow 🙏 2 main reasons come to mind after googling: 1. I overwatered thinking it's hard to do since I'm using the Air dome. 2. Too intense light. Was checking a lot of growers that actually grow 24/0 and went for it 75% 40cm.

Auto and regular plants in one box.
I got an auto plant in a box, waiting for flowering to start very soon. Light schedule 20/4. Now I planted a new photoperiodic seed in a same box. What should I do, keep the 20/4 light schedule before the auto plant finishes and after change to 18/6? Or change it right now?

Mars Hydro TSL 2000 questions
Other than recommended distance from the manufacture, how do I know how dim/bright the light should be? Also, since these are autos, do I flip at 5 weeks, or just keep going until I’m ready to?

Lighting Horsepower
I have a Horticultural Lighting Group 260 QB V2 R Spec light (260 watt LED). I previously had a 20" x 36" tent and the light was great. I have just gotten a 36" (91cm) x 36" (91cm) tent and wondering if this is enough power for great production or if more light would be better?

Grow Light for 3x3 tent
Looking for a good grow light for a 3x3 flower tent. -Price is not an issue -Low heat since I am venting into my living area. -Even light distribution. I plan on doing a SCROG so having the same light intensity on the edges as the center would be best.

How much light - PPFD - without CO2?
How high in power should I go with my lights without CO2 enrichment? I can comfortably provide 1200 PPFD to the canopy, but I'm holding it down near 900 because I'm not sure the extra power used would yield an increase in, um, yield.

Is 500 ppfd on new seedlings ok?
My light dimmer only lowers to 500 ppfd. I’m starting autoflower seedlings in a space tote before I move them into my perpetual harvest tent. I’m currently propping the light on its side so that the indirect light only hits around 300-400, as an attempt to reduce light bleaching.

Wrong power cable in my LED light: still light when switched down off.
Have you ever made this mistake? My second harvest was someway worst then my first. Sure I did some watering mistakes but during my chores in the room and in the tent, I found out. I used a random power cable on my PAR LED lamp so when It turned off still had some light on. Bang!

Help! Timer problem.
My timer on 18-6 broke and i'm not sure if the girls had 24 hours for the past couple days... by putting them back into 18-6 will that trick them into flower? Hope not. Thanks :)

Light schedule
I am doing an outdoor grow and also have a grow room set up for germination. Outside is only getting about 14 hours of light, is it beneficial to bring my girls in under my LED's for 4 hours to make sure they're getting a full 18 hours of light? then bring them back outside

Lighting question
I am running the Viparspectra 450w LED as my light for 4 autos in a 2x4 space. I am worried this isn’t enough, especially because of its lower levels of red. Should I upgrade to something stronger like a Mars hydro 600 or 1000 before flowering start?Or if not Mars something else?
