I cant see an iron problem so go easy on that stuff. Be patient my friend.. as the weather warms and you get some months on your system it will just boom. Trust me it will happen.

Had a bit of a growth spurt with the hot weather

December Update




Excuse the slow talking, was a few beers down at this point.
Note to self, record before beer.

Latest Update!

Looking good.

Love the video updates, very moody music on the underwater ones :-)

Good tip; stick your camera in a jar!

YAY!!!

Fish UPDATE!

cool system

Thanks,

It's not ideal yet - just need to save up for some 2mx1m growbeds x 8
Then I'll be happy :-)

Hi guys,

Having some bug issues lately, my tomatoes are being eaten out.. Not sure what from, moths or caterpillars? Lots of holes in the tomatoes and eaten out..

I have just tried some dipel - not sure how others overcome this?

Cheers!

Any ideas what the white spots are on the squash leaves?
I'm thinking of also running some 200L blue barrels down the opposite wall to utilize all my space..
What do you think ?

What's your pH? Looks like you've some deficiencies of minerals and elements, especially iron (yellowing between dark green veins) and maybe potassium (need a closer look at your corn to be more certain), either through lack of supply or pH lockout. If pH is OK (6.5 - 7.5) I'd be dosing with some seasol and probably a kick of chelated iron too. If pH is out of whack, judiciously adjust and see if the plants improve over a week or so; if not, then supplement with seasol, iron and maybe potassium. Continue to adjust the fish feed accordingly.

If your fish are still small and not taking that much feed, then you will not be able to "naturally" support too many more plants? What's your nitrate level? If you keep adding more GBs, then you may need to keep supplementing which has an associated cost; you'll also run the risk of getting nutrient levels out of kilter as not all of the minerals and elements in the supplement are used up by the plants and will build up over time, eventually breaching the "too much" barrier and that oversupply will be detrimental to the plants and/or fish. There is a fine balance; sit quietly one night and think some more about how the nitrification cycle "works" and apply this to your system as it is now and where you want it to be in the future. If you have excess nutrient, add plants and/or remove fish and/or reduce feeding; if you have insufficient nutrients, add fish and/or feed more; if you have insufficient filtration, add GBs; etc. etc.

The white spots look like a fungus or mildew? Spray liberally each day with a fresh solution of 1 part whole milk to 9 parts clean water, or, once per week with some eco-rose/eco-fungicide (contains potassium bicarbonate which will raise pH if it gets into the system water so use cautiously) If you can get the pH and/or minerals back into balance, the plants will be better able to fight off the infections and spraying will become less necessary. In any case, the infected leaves which are growing out into the thoroughfare should be removed to prevent the spreading of the fungus as people brush passed. Immaculate hygiene will help limit the spread.

Thanks Bunson -

I'll check the water levels tomorrow -= I assumed the yellowing was caused by the constant 40-50c demp in the greenhouse lately with every day over 30c

I'll give it a dose of seasol now,

Cheers

If it's your pH which is preventing plants from taking up the nutrients, there is no point adding more nutrient to the water (that could cause other problems) because the plants still wont be able to access those elements. Check your levels first, then take action accordingly.
