FIRST GROW!!! Vertical 330w CDM Allstart MH BareBulb 2x2x5 GrowBox

After a few months of research and sleepless nights (Insomnia) I'm attempting my first GrowBox! I think I've finally found a sound design for my space and budget constraints. Going to construct 2x2x5 GrowBox lined w/Mylar through the inside. Most of my inspiration comes from Scottyball Pineapple Express G-13 lab's Seed to Harvest, so I will be going that route with a few modifications. So let me know what you think please and any suggestions are welcomed!!!

P.S. Below is a picture of my concept drawn on paper, don't laugh I'm not an artist... :/

Its gonna be a prett nice setup when your done. I dont see any other nute's in your list? I would use more than just Flora Bloom. I myself am running Sensi Grow/Bloom A/B. Its ph perfect and a really good name. I just ph my tap water add nutes and done. I also use Voodoo Juice to give me perfect fast growing healthy roots. Oh and if i were you i would up the size of your room to 2'6'' to allow a lil more room for your plant to grow. Being that you are only gonna have 2' to 3' of actual growing space (vertically) you might want to think about more floor sq ft space. You can make your screen bigger and have more room for more buds. The light you have is not really enough either, even for a 2'x2'. Go to Walmart and get some 26w CFL's. They are equal to 100w bulbs (somewhat) snd if you put 2 in there on top of what you already have it would do really good.

I might increase the Length and Width a little I've been considering that these past few days, lol. I'm only using Flora Nova Bloom because of where I got my inspiration for this set up! Scottyball 400w CMH Grow so beautiful and all he used was Flora Nova Bloom through whole grow. My bulb should be fine, or at least I hope, lol. Im using a Phillips 330w CMH Allstart bulb!!! It's equivalent to its Phillips 400w CMH counter part from what I've researched. I could be wrong so don't take my word on that; it's just an conclusion I've come to from research not actual use. :/ I will deeply consider adding in a few CFL's around sides of box if need be though; it would only help my grow anyways! Also I will covering entire inside of box with Mylar!!!! I'm going to build the frame today to get a physical idea of size I can't wait. I will post a picture when I have assembled the frame. Thank you!
