Here is the skinny on these LED for growing your tomato plants gang...

You need at least 4 panels of 96 LED's (BLUE) and this works awesum for fresh cut clones.

FOr anything else, veg or flower stage, the LED setup will work but you will get very slim harvests.

LED's will be the future for almost all lighting in the future (say 3 years) but for growing tomatos and getting the most out of your efforts, stick with what is proven and tried and tested.

Right now, they will not produce big fat thick tomatos.
