Hi mate, everything looks good from here. If you are worried about it, download the light lux app. You can use your phone to measure lux which can be converted to PAR. MigroLight have a great video on youtube about it. 60000 lux is around 500 PAR. I hope this helps, good luck and happy growing

i have just been kinda guessing 1/3 further than specs will mitigate cross over from lamps in the middle and lower light levels at sides.

Trying to get setup rightI know I prob need to get a nicer light and ditch all the crap lights but for now I have what I have. Perhaps after some success I may be able to get a new light to replace all of them. But how far should it be? 2 feet above rockwool cube? And what watts per plantSetup. Lighting

I Made a Big MistakeI forgot the timer open and the plant has been lighting for 2 days now. Normally I have to turn the lights off at 6 pm. What should I do?
Should I wait until 6pm? Or should I turn it off and switch to a new light schedule?

Can you use a 450 watt white led light to start seedlings? If so what distance should the light be and when should I make it closer? The reason I am asking this is because I don’t like transplanting autos as they are fragile to transplanting from what I’ve looked up

LED distance in grow 80x80x160I placed the LED at a distance of 45-50cm from the seeds
and consequently it was about 65-70cm from the larger plant.
I have 4 plants
Is it ok like this?
I don't have a luxmeter and I use the phototone app to get an idea of the PPFD in each plant.… Show more

I've found some lights I have left in my garage, and since I would like to upgrade my setup, I would like to know if these lights could function as grow lights.

Setting up air cooled refactor.I've got a new air cooled light refractor, a tube like one. I've set it up such as the pic, I'm thinking of putting the extractor where it shows on the pic with the air flow going the way of the arrow, would this be OK? I can't find anything online about setting this one up.
