Funny old thing hps. If I have cmh on, then turn on leds, I still see mainly white light. If I run hps with cmh, I just see that yellow blur and can hardly even make out that the cmh is on. I know it's on though, also I know it works well by itself in a 4ft x 4ft area. It will all make sense when these flower
It's so bright in there, I can't even see the infared dot on the leaves from the temperature gun
I'm going to switch the plants round, the sad's on the right are slightly taller, so I'll move them to the left under the cmh, after their next feed. Less heat to them, few of the top leaves are getting shark teeth leaf
I have to use hps as well, as it's cold in the UK. It's an easy time to use lots of light, so I make the most of it. I have all my windows open 24/7 to supply all the plants with fresh air, if I added another 400w lamp, the ambient temps would be too hot. I've max'd out the ambient temps and am growing auto's on 24-0 to keep the C'99's nice and warm in the dark period.
I was using another cmh instead of one of the 400w's, but the ballast broke and fucked the lamp too, which has ignition problems.
Overall though, this is where my growing skills come in. I'm going to fill both these 4ft x 4ft tents to the brim with bud. in the next 21 days
