I now have a problem. The tomato plants are touching the roof of the greenhouse. I don't know if I cut the tops off if it will grow sideways or just make more shoots and keep going up. I don't suppose I have much choice, I'm not opening up the roof lol. The plants in the grow tubes are doing well, now I just need to add a few hundred feet more. I will have to put them outside as the greenhouse is full. I am going to try and grow more cukes, only this time I am going to put them in pots and raise them a little. I don't think they like the water to well.
