First Time Grower.

This is my first time growing. I initially started out with 18 plants, and after some died and i got rid of the males, i ended up with 4 healthy females.

They are now growing under a 1000 watt High Pressure Sodium bulb with a wing reflector. I also have 2 humidifiers, a heater, several fans and we use a window inside the home made grow tent to regulate the temperature.
The grow tent is a portioned off section of a bedroom, the tent is made from heavy plastic completely enclosing the area.

My plants are now about 4 feet tall and are about 7 weeks old. We are using PK 13/14 and Cannazym nutrients.

Sounds like you have a good idea what you need to do, good luck with the grow, looking good. Does the room run cold? Funny using a heater with a 1k HPS above them. What kinda temps you looking at?

im using the heater during the night. the temp stays between 78 86

the humidity stays right around 50 because its just starting to flower

sub'd good luck with your grow!
