Your post is a bit unclear, are you growing outside or inside? If inside, that weak light is the problem. Plants are thin and leggy because they are stretching for light... Even if they werent, 75w is way too little to even grow one decent cucumber plant.

Want some real results? Grab a 600w hps with a full spectrum vertical bulb, put treillises on the walls and grow your cukes that way. In a 10X10 room with 2 of these, i can grow about 15 indeterminate tomatoes, 15 cucumber plants, without using more then the width of the totes, or about 1.5 foot all around. That leaves the majority of the space free for other crops. Layer them in a stadium type shape and youll be amazed at how much can be produced indoors!

I think that tomatoes require a cooler temperature part of the day so they don't desiccated up. Anything over 80F is not good for the flowers. Try lowering to the 60's at night and heater during the day. You might get better growth then.

Anyone interested in used 350W metal halide high bay lights. Very reasonably priced.
