Question, to you and anyone else who uses a greenhouse...do you need to 'paint-brush' your blossums in order for them to pollinate, or do you open up to allow natural pollinators?
I see the photo of your tilapia was taken a year ago May...what has been your average harvest weight?...how many do you have in what size tank?
I leave the doors open so it can pollinate naturaly but you tend to get uninvited bugs at the same time you don't need. I am using IBC Tanks for the fishes and about 200 gallons of water on each tank. I was trying to keep 30 tilapias in each tank but things got out of hand and they started breeding too fast, Before I realized I had over 200 tilapias and my system became unstable, I had to give most of them away to friends. About the harverst weight, I could not say for sure, if it looks big enough to eat then it goes to the grill...LOL
