Are the yeilds the same as a hps or HID????I hear you. But, heat issues, AC power draw and 5 year lifetimes are motivating me to them.

Very cool. I am going to run over and check 'um out.
Thanks for the heads up Yow.
Those are cool, but the reason to spend money on the higher end meters is to allow control of your CO2 device through the monitor. It monitors the CO2 and turns on your generator or tank to keep it within a specified range.check out this co2 monitor for $130. staying with SB and being cheap this can save lots of money(no need for the high dollar systems but able to keep a closer eye on levels)

that is exactly the reason i liked it. if you want to run co2 you can do it cheaply. by using this you can adjust your timer and save $400-500. my co2 system(regulator/timer set, filled 50# tank,and this monitor) cost $302. with a couple of small timer changes it now stays close to 1500ppm all through lights on. why the need to vent? i use a sealed room.Those are cool, but the reason to spend money on the higher end meters is to allow control of your CO2 device through the monitor.

You may be able to work out a vent / refill schedule by using lamp timers and that meter though.
Cheers Lions bro yeh i think you might be onto something with the changing of the res more often, i been using a reasonably smal res and it makes me need to "top up" the res with fresh water to bring the TDS back to the desired level which in turn MUST be affecting it i thought because maybe the plant is using more of one nute type than the other? ? I might start changing the res more often! Does the plant use more or less nutrients at this stage of growth? ( i am at 7 weeks )My humble thougts on the yellow leaves:
Yes - yellow leaves such as yours seems to be the norm... Dirt and I have seen it around week 6. I believe Stink has seen it too. I think it is a combination of salt build up and heat - but I don't know? Next round, at the start of week 6, I am going to change my res a little more often, lower my PH to 5.5, increase my off cycle time, and run my lights higher above the canopy. Good news is the yields and the bud seem to be unaffected by the yellow.
In soil, yellowing leaves can often be a sign of overwatering. By week 6, the roots are quite big and long in the Stink system. The root mat holds much more water than the more singular root sites found earlier at weeks 1 - 3. By week 6 - my posts drip much water through the entire off cycle - as water is more readily held in the growing root mat. At week 2 - the water drains completely after a couple minutes. Also, humidity in most flower rooms is at an all time high by week 6 - lowering transpiration and required water. Maybe we are 'drowning' roots that were previously used to hanging in oxygen? Perhaps - try increasing the off cycle to 6 minutes if you have a capable timer (or 5 minutes, 30 seconds, if you have a DRT-1 or similar digital timer).
Your plants look great! The red hairs will come. What strain are you running - some strains will finish with fewer red hairs than others?
If you can accurately maintain your 1500 during lights on you don't need to vent. Unless you know the dispersion rate of the CO2 it can difficult to hit that 1500 using an unknown starting PPM.why the need to vent? i use a sealed room.
The humidity and heat stress isnt a problem, i have better than average ventilatiopn in the room and its all from a clean fresh air source.They looked good overall. Hows the humidity in the room. Mine do it some times when the humidity is up for a few days strait.
