Hi all, what would cause slow sideward trajectory? My purple lemonade is 5 weeks, it’s 32cm high, yet it’s barely growing outwards. Is this normal at this stage? (Very first grow) (photos) 4weeks and 5 weeks
I'm going to venture a guess and say you're light is pretty high above the plant if so bring the light or plant to withing 16 to 18 inch of the light and if you can turn down the intensity to about 50 percent for a few days and then slowly adjust the intensity if you can't just turn it up full and lower the plants a couple inches or raise the light
I good app for PPFD is tent buddy, it had a PPFD and DLI calculator also has a VPD calculator as well, great app just keep those numbers in the parameters and Bob's your uncle
the stretching is due to the lack of light just like the lack of side branches
I don't know how your watering is, but remember to let the soil dry out well before watering again
last thing, are you giving them something to eat?
Training techniques can improve branching, LST, HST. Some lights can encourage stretching. The light I have noticed the tightest internode distances with so far are dual spectrum HPS.
