Plants are looking good, just don't burn down the house with all those plugs, open water, heat and humidity. Safety first...a growcab is no place for open plugs. If you spray, be careful where the overspray goes. One "oops" cancels-out 50 "atta-boy's".

The effective light from CFL's only extends about 6 inches, depending on wattages. Unless trying to keep the heat in, the foil is really unnecessary.
