Last year we had blight in a poly tunnel . All the plants were in 10 or 12 " pots
We are planning to increase ventilation this season for next season .
My query is we are planning t to glow toms again in the same tunnel. Clean all pots and inside of tunnel with Jeyes fluid. Dipping the pots and spraying the polythene . Will this work and if so what concentration of jeyes can you recommend.
If not what else can you suggest
