Using a 4ft x 4ft x 8ft closet.
600 watt hps light hanging about 5 ft above top of the plant
( was originally about 2 ft above but it almost immediatly began to burn the leaves)
Using a commercial 24 - 16 - 8 plant food.
Watering every 2 days/ every 4 w nutrients.
As far as ventilation goes the closet door is generally always open unless i have company. It is currently ventilated by 1 fan blowing exhaust outwards (photo shows fan facing inwards, but it was turned around shrtly after the photo was taken) and 2 smaller fans circulating air within the closet.
I want to build a ventilation system that can work with the closet door closed and keep the space at an appropriate temp.
Its currently staying around 80 in light hrs and about 75 or less during dark hrs.
I have yet to check the pH and the PPM.
I dont know how to check my PPM, can someone explain it to me please?
Some leaves were damaged when the light was originally too close to the plant.
Here are some pictures attatched.
Please hit me with any info/suggestions/ideas/help that you can give me.
I'll take whatever information i can get on how to make this work! Thanks!
