Cheese & Lambs Breath

Things have been going well, had a bunch of aphids primarily on the Lambs Breath and a few on the cheese. I sprayed the aphids off the 2 LB with the hose in a different area than where I grow and sprayed the grow area every day with end all for 10 days and crushed every one I saw on the plants and removed leaves with more than a couple on it. The numbers have gone down significantly. I tried samples of the cheese and LB last week and was happy with the effects so the 3 are going to get chopped soon. The weather is getting down to single digits Celsius overnight and has slowed the growth significantly, but causing some pretty cool colors. The cheese is an 8 week flower and it’s in week 9 and the bigger LB is almost 8 weeks of a suggested 7-9. The smaller one has a couple weeks to go. Has anybody harvested with a couple aphids? Will they just bugger off or die once there is no juice for them to eat or should I give the buds a rinse to hopefully remove the stragglers? Thanks, Happy Growing 🌱
