So my friend told me he has some anti-algae chemical for the reservoir, so does he still need a lid? The only reason he doesn't have a lid is because the tub he is using was given to him and whoever gave it to him didn't give him the lid and he doesn't want to go buy a whole new tub just to get the lid. Would it be possible to use a piece of plywood or something in substitution?

First Hydro, Just a Couple Resivoir Questions A friend of mine is planning his first hydro grow and doesn't have internet access but wanted me to ask a couple questions: 1.) Do you have to have a lid on the resivoir? 2.) What temperature should the resivoir water be? 3.) A guy with 3 years of experience that is helping him get started recommended feeding the plants for 15 minutes every 2 hours, but my friend has read conflicting articles, some say every hour or as little as every 4 hours. What's the best schedule to keep for Rating: 5
