Temat: O mierzneniu pH Temat: O mierzeniu PH ...so the plants are finnished at different times. It is therefore important to pick a good mother plant to take your cuttings from. Cuttings should be 4 - 5 inches (100 - 125mm) in length and in good health. It is a good idea to starve the mother plant of nutrients for a couple of day's so the cuttings taken will be looking for nutrients. Prepare the rockwool prior to taking cuttings. This is a simple proccess but must be done 12 hours before cuttings are taken. SBS 36mm and 25mm Grodan Rockwool blocks that fit perfectly into the 75mm and 100mm Grodan Cubes, or can be put straight into Hydroden Clay Pebbles. Make up a bucket of nutrient solution to a CF reading of 10-12 CF and pH reading of 5.8. It is important that the Rockwool is not lying in a puddle of nutrient solution within the propagator and now too wet or damping off will become a problem. The cutting should be taken just above an internode and cut with a single sided blade or scalpel.... Źródło: forum.haszysz.com/showthread.php?t=19443 |
