what is your system like? how does it work? what else do you grow with it?
(very briefly unless it's your favourite subject & you just can't stop ;-)

This is an on again, off again thing.

Basically the nutrient is Part A added to Part B and mix at half
strength like it says on bottle.

Could be light as it was grown under 30% shade cloth. Basically gets the
full, morning sun, then the shade cloth cuts in as sun moves. I might
have to relocate it out into full sun and just start under a piece of
shade cloth.

Bolting is probably correct. Hot weather was a factor on some, but not
all. Did it even in winter.


OTOH, we scattered the seed heads from various lettuce last year on a
garden and this year we have about 25 square feet carpet of lettuce (Cos
style). We are amazed and have an elegant sufficency of lettuce for
tossed salads.

Even when they are obviously going to seed, they are doing it so slowly.
Received copious amounts of manure on the soil and lashing of worm wee.

i suspect they have their feet in so much nutrients that are bone idle.


Anyway, I am looking for peeps who might know to save me running a full
lot of experiments.

No good running them under 30% shade cloth if that is the problem.

Long term purpose, was
a) different sort of gardening,
b) indoor garden in "sun" room (has clear ceiling)

TIA
