I want to start getting clones from my gal. I currently have a similar machine to the botanicare 25 site cloner and wanted to know what my best option would be for lighting the clones? I need a cfl that is: reasonably priced and produces low heat what is my best option 1. GrowBright 4 Foot 2 Lamp High Output T5 With Choice of Bulbs 99.95 10k lumens 2. GrowBright 2 Foot 2 Lamp High Output T5 With Choice of Bulbs 79.95 4k lumens 3. SylverStar 4 Foot 4 Lamp High Output T5 With Choice of Bulbs (not this specific model) but similar which runs about $149.95 20k lumens VERY IMPORTANT-----> also keep in mind that I would probably like to add one more 25site clone machine in the future. thanks
