Added by on 2015-08-24 – This is Week 6 in the system and it is clear that more light is needed. Slow growth is apparent where there is less light and where there is direct light, the growth is larger and looks healthier. The light that I am currently using is (2) four foot fluorescent lights. I may either add two more fluorescent lights, or I can add HID light. I have a 600 watt digital light that can switch between high pressure sodium and metal halide bulbs. That should solve the problem. I prefer the fluorescent lights for keeping the energy and cost to a minimum. Thanks for watching!

    What is that brown spongy looking thing you're using to grow them in, inside the nutcups? I'd seen that when you first sowed the seeds, what is that? I've seen rock wool and I've seen perlite and lava rock but am not familiar with what you've used, am very interested in doing this!?

    I'm very interested in how the parsley grows … i have a heck of a time growing parsley in the ground and would like to make it

    looking at the setup it appears you are using a directional "t" joining the main dump line. does this leave a residual pond in the grow lines and if so does it alter your nutrient ph?

    not a little more light but a crapperload more light. even the stuff that is growing is stretching for light. Lets assume you have 25sqft of grow area. You need a minimum of 20w/sqft of florescent lights if you have t5's, way more if you have lesser inefficient lights. 20w x 25sqft = 500w of decent light is the minimum to grow that much space. A 600w metal halide with a light mover would do it so you could grow basil and higher light stuff than just lettuce.?

    bro, rotation…?

    you position the light wrong, it's suppose to be horizontal…

    I may do that because the growth was better directly under the lights. Great suggestion!

    I have a 600 watt HPS / MH combo, but I wanted to try the grow with fluorescent to save on energy and since I was only growing lettuce and herbs, that light was sufficient. Thanks for commenting!

    Yes, the pump runs constant. I will probably try cycling the pump for increased energy efficiency in the future. Thanks for commenting!

    Do you run your pump all the time? Im in the process of building mine and I bought a timer.. My setup is completely different from yours though.
