Hi Bob , if you are flowering in about 2 years then you are doing well. 2 years is about the best I have done in my system, although I have flowered a back bulb in 15 months, I dont know if this would count as it was a very large backbulb ! Anyway here's my method .
1) Use only strongest plants from flask.
2) Plant into 50mm X120mm root trainers . The media I use is coconut husk chips which has been rinced out a number of times in rain water. the ph should be arround 6 . I aim for an ec below 300 microsiemens.
Some of the blocks of coconut hust are so loaded with salt that I sometimes have problems getting the ec down to acceptable levels
3) The pots are placed in a tray which holds about 5mm of nutrient , A few of the pots in the trays receive dripper tubes through which nutrient is pumped
3 to 4 times a day (depending on daytime temperatures)
4) The fertilizing programme has a 6 week cycle .
Week 1&2 50% magnesium sulphate and 50% multifeed ( a medium nitrogen hydroponic feed)
Week 3&4 Multiffed only
Week 5&6 Calcium nitrate only
Ec March to October 300 to 400 microsiemens
November to February 400 to 600 microsiemens
5) The ph of the nutient must be between 6 and 6.8 I add dolomite lime to the pots every 4 months this keeps the media " sweet"
6) The nutrient is aerated 24/7 and I give the plants an oxygen boost every few days using Hyprox. Also very important I heat the nutrient to 16 to 18 degrees celcius do not exceed this temp as it drives off the disolved oxygen. Well I have come to the end of my typing ability for now would you u like to compare notes on your system ?
