Hi buddy Syd Barret !
I'm glad to see you are having a try at those .
For me Sweet Seeds is : 12 seeds popped , 12 plants grown and 100% satisfaction .
Nice selection on tastes . Strong worked auto .
Just smoked 1 Killer Kush Auto Joint and I'm high with nice taste in mouth .
Crystal Candy Auto candy orange taste can make you junk about her taste !
You are aware on Cal/Mag issues so you can start them 24/0 hours of light for few days .
Blue white spectrums keep them growing more while leds full spectrum makes them blooming a little bit faster from what I observed .
Also to avoid mold a lot of little plants are wiser than making compact big buds for sure .
Have a good grow with them !
