Propagation for 2009 - 02/02/09

It took longer to clean down all the systems and paint the floor than expected, in a heated greenhouse i would have liked to have started my seeds off earlier to give them a head start to the season.

I'm propagating more seeds than whats needed just incase some of the seeds aren't viable and so i can pick and choose the better plants later on.
I've also used a selection of different propagation media incase i have better success with one and not another. I've used 1.5" rockwool cubes, fleximix, jiffy 7 peat pellets and a new media called sure to grow which is like pillow stuffing.
I pre-soaked everything with VitaLink Plantstart and BioPlus, two great products for getting well rooted little plants. I set the EC to 1.0 and the pH to 5.8.
I am using a T5 LightWave 8-Way flourescent lighting unit above the propagator and i'm really impressed by it. I can choose to have 4 lights on at once (4 middle tubes or 4 outer tubes) for when they are young and all 8 lights for vigorous growth when they are large enough.
Sometimes when the sun came out temperatures would reach above 30°C in the propagator, it was essentialy a greenhouse inside a greenhouse. To prevent cooking my young plants i used black and white reflective sheeting to reflect the suns rays away from the propagator, and lifting the light away helped. Opening the vents helps cool down the propagator but drops the humidity levels in there, I can keep an eye on my temperatures and humidity levels using a hygro-thermometer and it tells me the maximum and minimum levels of both readings.
Now i'm waiting for seeds to germinate i can organise the rest of the greenhouse.

A Fresh Start

Last year's grow was a steep learning curve for me. It ended well with lots of fruit and veg for staff at aquaculture and most of the customers who came to visit.

However there were a few problem issues such as god damn mealy bugs, it was near impossible to control these fluffly sacs of goo. They appear to be imobile but managed to get into all nooks and crannys they could find and laid hundreds of eggs that spread throughout the greenhouse carried by the wind.

As the growing year drew to an end it became a good chance to completely clean down the greenhouse and start a fresh.


I started by dismantling all the systems and cleaning them down with hydrogen peroxide, it's safe to use and doesn't leave a harmful residue like bleach can.

The paint on the floor had been annoying throughout the season and was chipping up. I attempted to bring up any loose flakes but when i realised i would be there for days lifting the whole layer off, so i decided i should just paint over it and hope for the best.

With a new lick of paint and a wipe down the greenhouse was ready to start a new growing season.
