Veggies in S/H

[DelawareJim]

Well I've been doing S/H for 18 months and like it so much I've converted almost all my house plants to it or to hydroculture as well. I’ve also learned a lot about hydroponics in the process.

So the next step is veggies. I'm experimenting with some lettuce in S/H in my basement under lights and they do okay, but not as well as a hydroponic lettuce in a greenhouse; mostly due to cooler temps and underpowered lighting (40 watt shop lights versus a 20,000 lumen HO T5 fixture).

My next trial will be S/H tomatoes outside on the deck. Has anyone tried this? I will be growing in either a 5 gallon bucket or a 15 x 15 x 15 square planter.

My biggest question is if the drainage holes should be proportionally higher? Since the drainage holes in our 4 to 6 inch containers are about ¼ of the way up from the bottom, should I go up the same ratio (3 ½ to 4 inches up from the bottom of a 15 inch container)?

Any experience with this Ray?

Cheers.
Jim
