ok, stay away from the use of foil as it give off alot off heat, what i can suggest is that u can geta shoe box minus the cover, line the inside with mylar and use that as your reflector,,it's quite easy to do
Sorry for changing the topic , but i have a major issue, I was doing some LST but i broke my stem close to the third node, the plant is about 1 foot...what to do? will it grow from the third node?
