Don't look bad, but they are getting leggy.. Put a fan directly on them, harden them so they can tolerate a fan full blast... Needs brighter light, as close as possible to the plants... What are you feeding them? What kind of hydro are you doing? All an all, don't looks to bad, but I would get a fan on them and a brighter light, nearly touching the plants without harming them.. Joe

Thanks tessa for the compliment. It's my very first time to grow tomatoes and I've tried so hard to learn whatever I should from books and from internet. I'm quite happy about the result, but I am kind of disappointed about the taste of sweet 100 and the early girl that I bought in a garden centre. It's not as sweet as I thought! I found that there are not much as a choice for me to choose from in a garden centre. Should I go buy seeds from internet next year to try something like sungold, black man sea or just something that I would never find in a local garden centre. Please give me some advise.

Roots need room to spread and breathe. Also, remember to put your vine support in at the time of planting or shortly thereafter to minimize damage to the plant(s) and plant a marigold or two in your pot to help control pests. Try planting Super Sweet 100. One of the most flavorful cherry tomatoes there is, IMHO of course, and with care will produce fruit until a freeze here in the Austin Texas area. Now, if I can only find some cheap 20 gallon tubs for my plants. I want to experiment with location in my new yard before installing permanent raised beds so anyone who reads this and might have a source for me please answer back. Happy gardening!!
