He must be polling your leg.
Promix has a line of actual soil.
But it could never sustain a plant for 3 months.
Was it in a pot?
Or did he have a hole in the ground full of it?
In the ground might work.
Sun and led light was a great combo in the greenhouse.
Our summers aren't exactly the sunniest so the led supplement was vital.
Next year more light spread out better.
I had 1100 watts at one end and 300 at the other.
Poor planning but a last minute fix.
We will see who wants to sponsor it and what they have.
We are with Ontario Hydro here.
Rates aren't horrendous but not cheap either.
I'm thinking solar down the rd a bit.
We don't get much sun so it may be pointless.
Hopefully they get more efficient in the coming years.
I've other projects more pressing.
Like the dam boiler.
They hooked it up wrong.
I have to switch it on and off to get hot water.
Otherwise it just runs forever, fek.
And the grow room needs finished asap.
Lots to do before we think about solar.
Hope everything is going well my friend.
Nice of you to drop in.
Take care.
Stay safe
