Hey friend, Congratulations on getting into indoors. First off, AMAZING setup. I did this same type of build around 9 years ago with uniseals & 5 gallon buckets except I did a room conversion with 2 8 plant systems. I do not want to hijack this diary but if you want to see them check out Chronicknowledge42o on youtube ( it is younger 20 something me with not nearly as much knowledge so ignore that aspect XD )
Secondly, Would you be alright with me offering you some pointers to help you out with basic indoor growing info? First off, I know you are in a custom build I do not know how much manipulation of the environment that you have. With that said I will continue, Cannabis plants love heat and humidity. It is the buds that hate it, We can speed up our veg with warmer temps & a bit of humidity in the environment for the leafs to have some foliar intake to back up the smaller roots during this stage of growth. The first 2-3 weeks from seedling life into young plant life it especially helps. Good veg temps are 79-84 MAX all the way through veg & no more than 9 degrees less with lights off.
The humidity of 60-70% for the first couple of weeks works great too. The reason we want to keep our temperature gaps within 9 degrees less with lights off, If we expose them to fluctuations larger than that in veg or early flower we cause our plants to stretch a lot which we do not want. Once our plants finish growing vertically by weeks 4-6 of flower with photoperiods & with autoflowers we watch for this by eye, Once it happens we can then open up our temperature gaps between lights on and lights off as now it will send extra energy into the budding process and resin production simulating the ending of the season is nearly here. We can also use light deprivation in the last 2 weeks & cold feed temps the last week before chop to further this process.
If you do not know about it yet check out VPD, Vapor pressure deficit and how it relates to growing cannabis. All growers should learn how to use a VPD chart and log their rooms numbers, Grab a thermal laser temp gun like the fluke 62 MAX & a PAR meter if you do not have them to better read your plants and grow to their needs. This equipment also helps us dial our plant to light distance in optimally. If you do not have them grab yourself some sungrip light pulleys to help manage your light to plant distances really effectively. If you want to see how well these work check out my 200 light 7,000 plant diary it made moving all the lights managable lol. If you ever have any questions feel free to ask I am always around to help out friend. Happy growing!
