LUX meter grow question
dauntlessstarted grow question 4y ago
Can someone check out the LUX meter video and tell me how I should be positioning my lights? I think maybe I have too much light on them.
My meter says 600 (x100) that puts me at like 60000 lumen. The converter I used put that to 1541.36 umol/s/m2 which is a lot of light already

Idk which meter you are using. But because you are using leds and hids they have different wave lengths and you need a meter that you can get 2 dif readings off and then add them 2gether to get a true ppfd map. Here's what I'm talking about. Use this and it'll give you a proper lux reading. As 60000 lumen from a high led light is only in the 800 range. And the SF1000 is only rated in that range, but you are using another light with a dif wave length.
Good luck

You want to position the probe level with the canopy, that's the reading you want because that's what the plants getting. If its to strong either lift lights away or dim light power until you hit the reading your happy with.

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?6y ago

Irregular light schedule.I am thinking about giving her 24h lights a few days a week and then go back to 18h. Just to give her a boost. Will this irregular light schedule harm her?
My first thought is that it doesnโt matter much since she is an auto, however I know that plants love balanced environments.Week 3

UV LED slowing down growth? Sorry previous question without the question!The plant has a rectangular area in the middle where it is not growing as quickly. The difference is almost 10cm. I suspect the lamp. Could it be that the centrally installed UV LEDs are causing this? They should grow more inside because of more light.

Cycle 18/6 or 12/12I dont know yet if do a 18/6 of floration or 12/12.
The my idea is to do 8 weeks no more. I dont have time.. then maybe is better keep the 18/6 of cycle and change just the led in lamp led floration?
The first plant has been moved in the soil the 25/2 with 6mm of root

Light height full power vs dimmedHi, with light height, does it make a difference to the plant if I'm at full brightness and further away vs dimmed and closer? I'm going to start running out of tent space soon so I'm expecting I'll need to dim in late flower. I think it's ok just looking for assurance :)
