polystyrene beads
Hello Ron. I live in the tropics and plan to use the 2-litre bottle system for tomatoes using ebb'n'flow.
We get about 12hrs sunlight throughout the year. I've read somewhere that a possible medium to use is 1/4" polystyrene beads (those found in 'bean bags'). Since they float, I've got to weigh them down somehow. I can find rockwool here, but they are for heat insulation. My question is: are any of them suitable? The other thing which is holding me back is nutrient. As tomato hydroponics is not yet popular here, I cant seem to find suitable nutrient. nutrients for green and leafy vegs can be easily found.(168-40-200, I think) Other than that, I'm all go. The 4 x 3 rig and pump are all set! Best Regards, Azhar Ahmad |
