I would recommend getting dried/dehydrated vegetables and then just soaking what you’ll feed your turtle so it rehydrates and you have the rest stored. That’s why I do with my turtle. I bought dried carrots, bell peppers, squash, sweet potato, and zucchini. I get them all at Amazon, and I soak them in hot or warm water for about 30 minutes before feeding them to my RES. I’ve have the dried vegetables since last April and haven’t run out :)
