I've just gone by Jorge Cervantes 'rule', he says optimal without co2 is 75F for flower. Either way I'm no expert but the plants are thriving. Third week of flower and right plants are consuming 15 gallons of nute solution per week in rdwc. Ppms at 800.
Do you think I'll see any negative effects with the temps I'm using? Honestly bringing the temp up to 85 would make the nute solution temp unmanageable, I'd definitely need a bigger chiller. The way I have it setup now, the chiller only needs to kick in twice a day and my nutes sit at 68f all the time with the chiller not needing to run with lights off at all. I appreciate you chiming in on this discussion, I'm here to learn.
Thanx. Plants want 85. Cold plants grow slower. Highest yields with high resin are achieved around 84-95 degrees. Strain spacific. Are you useing silica in your nutes? Vitamin K and sulphur increase yield and potency. But they are best uptaken at higher temps. Silica will allow you to get those temps without stress or shock to the plant. Soil temps around 65 to 72 is good but other temps close are fine. Nutes a little warmer are ok but you could have less oxygen in then. I'm a soilles soil guy and organics. Used to grow hydro. So some compromises have to be made because of many other factors. Also night temps shouldn't ever go below 65. Prefer above 72 all the time. The colder it all gets at night, the longer it takes to warm up and start growing at a decent rate..
