Hey there, Would it be okay if I offered a few pointers to help you out? So cannabis plants love heat and humidity it is the buds that hate it. Your temps for this stage are way to cold. We want to get good fast vigorous growth and get out of veg into flower ASAP. So we want to look for temps around 80-82 (84 MAX) with lights on and no more than 9 degrees less with lights off. We do not want more than 9 degrees less when the lights are off if we allow for a larger swing in temperature than that it will cause the plants to stretch at this stage.
If you haven't gotten them already get yourself a PAR meter & a thermal laser temp gun like the fluke 62 MAX they will really help you better read your plants and grow to their needs. Check out vapor pressure deficit and how it relates to growing cannabis it is a really neat tool to utilize.
If you ever have any questions feel free to ask. Check out my 200 light 7,000 plant diary and follow my profile. Happy growing!
@JsGrowShow, I see, Just trying to help friend! I do have some experience with hydro myself I built 2 undercurrent systems back in the day 8 plant 8 gal buckets and uniseals. That still seems a little on the cool side. Good luck friend I will be staying tuned.
