Growing Watermelons with ExploGrow™

Posted to Hendrik Putter’s Farmers’ Union group: 

“Here’s a comparison for you to see what a difference the ExploGrow™ made!” 
“Both watermelons are from the Crimson Sweet variety. The only difference is that the biggest one was planted 2 weeks later! Same water, soil, etc.”

Mr Putter also shared this email to his Farmers’ Union: “We expect Crimson Sweet to grow between 8 to 9 kilos. The watermelon on the scale is the same one as in the photo above, it’s not my biggest watermelon  yet weighs about 11kg! I DEFINITELY recommend that you use this product! Remember, seeds were not even treated!” Hendrik Putter


Lab results: Brix (sugar content), appearance and taste: 

“These Brix results are substantial, however, the most important test for me and the laboratory staff, was the taste. There was a remarkable difference in taste.The treated melon was sweet, juicy and a nice dark pink colour. The untreated one was very slightly sweet, lighter in colour and texture-wise also different.

Head of our laboratory and QC, Linda Willem, and one of her assistants, ate both and where in agreement that the ‘explogrown’ one was far better. It is the sweetest watermelon I've ever tasted! I believe that this result will bring ExploGrow lots of business!”

“Hey ‘oupa’ we tried the watermelons and the treated one was much better than the normal one.” André & Leah

Spar Somerset called me and ask for more “EXPO” watermelons, nothing else! When my wife gave me the message, I almost fell out of my chair! I dropped off 400 on Friday and they sold out in three days!Hendrik Putter, Watermelon farmer
