sorry for slow reply!
i use a 250w mh for seedlings and veg but a fluorescent light will be better than an hps. obviously you dont start the seeds in the nft tank...
Bluefunk Reviewed by Bluefunk on . NFT Setup - HELP ME!!! Hi, Just a few questions, i am a complete novice. Gonna start a grow using NFT. 1. Am gonna buy budget kit from Growell.co.uk, includes 250 w hobby bulb, is this bulb good enough for 2-4 plants?JK What sort of yield would each plant produce? 2. Gonna grow in a Growell Grow Tent 1m x 1m x 2m, Do you recommend any ventilation products to help with heat distribution? Rating: 5
