What type of growing medium works best for very hot weather and i am thinking of building the barrel system they have on here .How would i grow from seeds? |

I like hydroton, but it's expensive. I use either lava rock(scoria) or river stone(3/4-1", I think that's 25-40mm? on the bottom, and clay pebbles on the top few inches. You can start seeds directly in the media beds, or use rockwool or seedling trays. A lot of options. Some ar eusing Grow Grips, but I have had zero luck with them germinating. |

The larger seeds like lettuce/peas/corn will usually germinate in AP direct. Smaller things usually have a poor germination rate. This is my seeding bed: |

Colum, you think lettuce seeds are "large"? I guess compared to mustard seeds. |

Large in comparison to other things. They grow very well direct sown, I've tried basil with nothing. Tomatoes are quite hit and miss. But anything bigger than lettuce go well. |

I find seeds in AP a bit hit and miss, particularly in warm-hot weather if they don't get enough water. You have to hand water and/or raise your water level up a bit to keep small roots moist. I find much greater productivity with all seeds using a simple seed raising stand. Just runs for 1min 10am and 3pm (twice per day) and I re-use the plastic seed trays I get from hardware/garden store - or else you can buy them very cheap. Use commercial seed raising mix and slow release fertiliser pellets with bit seasol/foliar every now and again. Germination to plant out rates are very fast and I can bring tomatoes to first flowers and basil, spinach etc much quicker than AP. I then simply transplant into my AP beds and/or wicking beds and re-use seedling trays ready for when first stuff picked. The seedling stand is only 1.2m x 500mm and fed with overlapping microjets. Water is caught underneath in a cut down IBC 300mm high sump that I grow duckweed in to add to fish tanks. ----- on media I did try cracked pea gravel (a local WA gravel product) but it simply got too hot and also heats up the water returning to the FT. Lost quite a bit of water [edit: to evaporation] keeping water level up high. IMO clay media is best as it also tends to wick up a bit which helps the plants *but* the cost is an issue. In my buckets and small beds I use gravel at bottom and clay on top - the gravel stays wet all the time. And the clay is in the flood and drain sections. |
