3 days since planting onto the slab and the tomatoes are doing very well. At this point I give them each 300ml of nutrient solution at EC 2.2 and pH 5.8. A small amount of run-off drained out the slab on doing this.
I have placed a support cane in the block to prevent any plants from falling over. I will get round to using the roller hooks over the next few days. With the roller hooks the string is tied to the aqua tray and goes up to the roof where the wheel and hook rest on a support bar. This allow the vine to be supported by the string and lowered when they get to too tall.
At this stage it is very important for me to maintain a relative humidity within the greenhouse of between 60-75% with temperatures reaching a maximum of 25-26C. This environment will enable the plants to set off well without being under any stress through excessive transpiration (water loss). The day lengths are still being extended to 14 hours of light using 2 x 400w metal halide lamps.
