Would you please explain to me how you do the 'drench'?
I only recently started s/h growing and now how some phrag and lycaste pots that have serious algae growth. I haven't done anything about it cause I don't have a clue how to go about it (even though I have some physan). Maybe I've let them go to long and I'll have to start with freash media before its all gunked up?
Generally speaking however, if the pots aren't too gunked up and you were doing yours :
Do you tilt the pot to get out residual liquid and then run buches of dilute physan through it or what? Do you leave it in there? If so, how long? Do you have to flush it out well with water afterwords? Should you generally do this periodically as a preventative measure even when you don't see algae growth? If so, how often? Any details I missed? Any s/h potted genus or species that tends to be negatively impacted by this type of treatment?
Lastly, is it OK to use the pool algacide stuff instead of the physan for this?
Sorry, I know, that's alotsa questions.
Thanks for your consideration.
