16/5/22: Week 3: VD15 for both. AN stands a little taller. But she comes of enzymes and TP goes on them this week, following their guidelines as far as when to give them the nutrients but I'm far of giving their recommend dose. 15.5 CM for AN GROW & 14cm for TP GROW. Both have been put into the 150x150x220 homebox and I have my 70x70x160 inside my big tent, this will allow me to keep the RH high in that tent while the photos veg and autos will be in full bloom.
17/5/22 both girls were topped above the 5th node.
18/5/22 Figuring out how VPD works. You could read for hours about this stuff and still not dial it in for years.
But here's the basics. VPD 0.4-0.8 kpa for early seedling. So under or around 23c and around 50-60 RH. atm my VPD is 1.05kpa and for most of my plants the optimal range is .8-1.1 kpa. Temp is 80 F 25C and RH is 70%. To find the perfect VPD (Vapor Pressure Deficit)check out optimal ranges of VPD for growing stages, also your strain should have the optimal VPD. I don't have an infrared temp to check the LVPD (Leaf Vapor Pressure Deficit) that's a whole other ball game. Im not going to get too boged down at the moment with VPD&kpa. As I said that's in a whole other league. Im going to run a basic VPD environment though. In heavy flower my temp will defo be in the 26-28 range as I'll have the 20L dehuimifier in my 5x5x7.
22/5/22 Solid growth coming from these 2 ladies. 15+ cm growth in a week is great. Hopefully I'll get another 4-7 days of growth before they start flowering.
