plants are going to start falling over
 

Thanks for the answers Ron I have a few more though..... i'm a little worried my plants are going to start falling over.... Again I am growing tomatoes and they are 2 to 3 weeks old. The water was getting dirty and i took the plants and put them somewhere so the water could drain out while i cleaned there tank.... i left them out of the tank for the day so the dirty water could drain a little and in the morning i would feed them some fresh new water. I came home this morning and the rockwool was still water but half what it usually is and a few plants are falling over a little so i poured some reverse osmosis water over them... no minerals and a few more fell over.... One day without any new water is that not good? they still had water in the rockwool... I propped them up with bottles till the morning. Will i need to put up sticks or something for them to grow against they are still real young and other tomato plants i have seen looked like they didn't ever need to be held up. Any thoughts? If it helps any i posted a few messages up from here

thanks Brett kalluminati2001@yahoo.com

Tomatoes can come back from no watering after about 24 hours if the roots do not dry out but no longer.
And yes you have to build some king of trellis system to hold the plant up especially when they produce fruit.
