What light do I need?

by Angela
(U.S.)

I've been successful growing lettuces under regular fluorescent grow lights, and another kind of plant with a hydroponic bubbler system under 600 watt conversion. I'd like to try some tomatoes and bell pepper though to add to my indoor garden, but I'm concerned about how much light they will get. I've seen the lighting chart (very helpful!) but I just don't get the coverage without supplemental light under the "canopy". Tomatoes get so big, and bell peppers are short. Could I get by with one conversion light? Would 400w work or do I need a 600w?

Answer from Stella/Simon:
Hi Angela,
You have hit on a problem that many have written about; how to provide light ample light for both tall and short plants? Unfortunately, there is no easy answer to this problem.

Lettuces do indeed do well under fluorescent grow lights, but bell peppers and tomatoes will definitely require HID lighting, specifically HPS when they are in the flowering and fruiting stages. You do not indicate how big your garden is; a 400 W HPS should be ample to cover a 4 x 4' space. The tomatoes might get too tall, and I would suggest you pinch them down and try to make them more condensed and even maybe branch them out at a lower level.

Hope this helps!
