About your "box", are the sides closed? you use any reflector? I got metasilicate, in powder, to prepare 1 litre solution, but it is suppose to last for 8 hours only. I can't spend more than $3 (in euros, I live in Spain) everytime I need to develop a PCB, and also, because that litre of solution is capable of developing 20 boards. How can I get rid of this??
