Over the last few years quite a few questions have been asked via the comments throughout the site. I thought it’d be nice to collate a few of the best in their own section. So without further ado I’m happy to announce the launch of “Ask Percy”!
First we have a question from Frederik.
Hey mister, thank you for the awesome website.
I have one question: After a cycle of growing, do I need to throw out all the contents of the bucket and refill it again with new material or can I keep the contents but just add new nutrients?
I really appreciate this! Thank you so much.
Many thanks for the kind words.
Good question. I have recycled the contents of a hydro bucket (perlite and vermiculite mix) and things went fine on the second grow. I assume that you did a good flush at the end of the previous grow so that the nutrients have been washed out well.
If you have a gardening sieve it would be a good idea to pass the perlite etc through it to remove the fine roots of the old plants.
Then it would not hurt to rinse it through again with water. In case you have an issue with algae you could rinse with a little hydrogen peroxide (well diluted). It will evaporate away. I hope this helps.
All the best.
