why 2 heaters? 4x 24w bulbs will give you enough light for most plants, but at that point you might want Co2. Pressurized would be your choice but if you do not have that kind of money go with a DIY Co2 yeast creation. Use 2x 2liter bottles connected to one line with a T-valve. I would suggest also using a plant substrate like Eco-Complete, it will fair much better for your plants. Also be careful with gourami & angel mixes... My gourami one day decided he didnt like my angels fins at all...
