Gardeners who've enjoyed "bumper crop" results with our Original Tomato Booster the past 9 years had just one request: Could we make the booster grow tomatoes even bigger, better and faster? So we rolled up our sleeves and developed this brand-new, improved model! Our new, big red Super-Gro Tomato Booster offers a larger, 1-gallon-plus reservoir, (50% more capacity than the original!) and a fourth fertilizer cup that provides four-point drip irrigation. Two extended "wings" collect extra water for irrigation, plus its big 25" x 13" "footprint" chokes out more weeds. And research shows that the red color stimulates bigger growth and earlier ripening.
