Appreciate advice /info on this little symptoms.
I just done my first hydroponic with White Widow auto and got just over 100 gram ( wet) for single plant… Did not grow big around 50-60 centimetres, buy the buds are fully loaded ( using led).
The only thing i found that towards the end i noticed green, algie looking deposits on my container and around my little stones in mesh holder.
Is that normal or I’m missing something?
some algae is normal to prevent it keep containers light proof and keep top layer of lecca dry
Appreciate, thank you for your info. 
. Wasn’t much but was not sure. Possibly because i cud only use white container.
Paint it easy fix
Will do Donald
