I have been going over and over various different designs for my growroom over the last couple of weeks and I cant decide on what I want to do. What I need from you guys is some ideas on what would be an easy to maintain, functional grow cabinet. Here are the few requirements that I have to deal with:
1. there is no height restriction
2. I need to use the minimum amount of surface possible to comfortably fit three indica (bushy) plants
3. I have never built a growbox before
some things to keep in mind is that I am a rookie and would like to possibly get into the ScrOG method. I have no idea about lighting and all I do know about the lighting that I will be using a HPS system. I don't know whether I will be using a 250W or 400W. I don't know what the advantages/disadvantages would be between these two lights.
I am really depending on the experiences of you guys that have been gardening for a while to help me hit the ground running. I am all about paying it forward and will really appreciate your valuable insight. Thanks alot to you all in advance. Let the brainstorming begin!!
