Decided to grow some of the most vigorous Hoyas in the ground in the greenhouse floor. It did get too hot in there durring summer but i opened the back side so that wind flows right through. Ill also add more shade cloth. Im going to leave them in pots and let the roots attach through the drainage holes. Ive done tbia before in my old greenhouse many many yrs ago. It looked really cool! Difference now is that this greenhouse is like a huge trellis. :) icrassata is already attached.
