I desperately needs information on growing marrows & pumpkins in a NFT system. Present system is 110mm diameter by 3 meters long. But I can change to any other suitable system . What size/space is needed for the root system? Which is the best medium, perlite, gravel,bark or gravel ??
PH & CF for marrows ??

Any info will be appreciated

Thanxxxx
