OK, so I have set up my greenhouse with growbags and an irrigation system, and am having good results with growing several varieties of tomatoes and chilies. I'd prefer to automate the feeding of my plants though, so am considering adding a Venturi injector onto the main feed lines so that I can add feed directly via the drippers.
I'd like to know:
- Is mixing Tomorite with every watering a reasonable idea or beyond stupid?
- If it is reasonable, how should I adjust the amount of feed? The bottle says 4.5 liters + 20ml of feed per bag, twice a week, but for continuous feeding, I'm assuming I'd need to set the feed amount to some ratio that's much more dilute.
- Has anyone done this and had success or problems?
I received a reply from the manufacturer:
Thank you for your email regarding Levington Tomorite.
As yet we have not tested this product with automatic irrigation systems so cannot offer any advice. Continuous feeding can lead to a build up of "salts" in the compost which can harm plants if not flushed through with clean water on a regular basis.
So to be on the safe side, rather than add a weak solution to the drip feeder, I'm going to opt to leave them unfed during my time away.
