Hi dude, Nice reflector man, its simerler to the one I use
I use. I highly doubt you'll have a problem with plants fighting for light when you have a nice bright powerful 600 in there
Nice tidy setup you have there too, Also
SCROG is a great method to train your ladies low profile and it also allows maximum light coverage and even light coverage which in turn rewards you with nice big buds and lots of them... More so than if you just let them grow vertical like nature intended
I put a couple of Bar Heaters in my grow space connected to a thermostat so when the temp dips below say....24oC then the heating comes on and brings the ambient temp back up to 26oC
Perfect and the thermostat is fully adjustable so you can modify the settings to perfectly control your rooms climate, (The Thermostat also has a socket for cooling so you can bring in more cold air should you need it in the event that your room becomes too hot...So look out for a stat. They are brilliant
also if you use erm a milk crate etc you can elivate your pots and reduce the coolness the ground transfers to the pots....Hope that help man - STELTHY
