I am trying a homemade hydroponic system this year to grow 24 chillies, I am also growing plenty of chillies in soil as well and the. The system cost me just over ?100 to make but I am sure it will repay itself as I don't have to buy soil and the water is recirculated. So far the signs are good, the hydroponic chillies have grown a lot bigger than the soil grown chillies.
I don't use any lights to grow the chillies, they are grown in a polytunnel. If anyone wants the details of how to set up your own hydroponic system let me know and I will post the details.
This years chillies: Bhut Naga, Purple Jalapeno, Bulgarian Carrot, Scotch Bonnet, 7 pod, Red savina, Fatali, Habanero Chocolate, Hungarian Yellow Wax, Serrano Tampiqueno, Fresno, Scorpion Trinidad, Red Savina, & Peter Pepper
