Hello lads, I have a diy RDWC system with airstones, just like the current culture ones. I had root rot in my firts grow and have had it ever since to some extent, just getting a bit fed up now. Lost full grow after full grow with a few decent grows in between. I now have 10 plants with the rot again due to the 3 day hot UK weather spell, came on in 2 days and crippled them. I can't really afford to buy or run a water chiller but res temps are not to bad 22 max in summer. I am running live with Hydroguard, tried sterile first grow and it was disastrous.
The advice I am asking is there any way I could convert this system to another type of hydro. I have been thinking flood and drain or aeroponics, anything really. If I can't I am going back to coco DTW. Can't take anymore losses.
Would this work? Normal pots suspended where net pots would be filled with Rockwool Cubes,these would be irrigated twice daily from main reservoir which in itself could be fed from a larger reservoir to keep it topped up. The system would be recirculating and changed weekly with fresh nutrients.
The only adjustment I would need to make is a larger hole for the pots to go where the net pots are and a simple irrigation line from the main reservoir. My tubs are quite tall so a good gap between the pots and the nutrient level would be achievable. Sorry about the crappy drawing. This could be a 4 to 10 pot system in 2 rows.
