Time to Walk the Walk!

So I will be doing a DWC in 20 gal totes. I have 10 white widow seeds, the brand I believe is seedsman. My plan is to grow these seeds out and get a couple of clones from the strong plants to be mothers (that will go in soil and give me a good long supply of future children to work with in my grow box).

OK so I built a grow box in my garage its 8'x4'x6' tall. Now I know how Noah felt. Check it out. the places with no white paint is where the mylar will go, it should arrive tomorrow. Got my carbon filter and air outlet, small air intake, fan assisted, I have 2 400 watters HPS for inside and will be getting a 1000 MH/HPS to go in between the two 400's in a week or two - that should be plenty of light right? Fill you in more soon...

I germinated the seeds last night, 9 of the 10 were ready this morning. I put the germinated seeds into starter plugs( I believe thats what they r called) today and have them under T5 lights. My first question is are the new seedlings OK under light right now, they r just breaking out above the plugs. How often should I be wetting them, dont wanna dry them out and turn em into toast. Heres some pics of what I am using for lights, my T5's, I will use this until they get a little bit bigger and then the 400MH for them. Heres the seeds I used as well, anyone got any feedback on these genetics...

The 10th seed has germinated so its in with the rest. Thats them all under the lights. The seedlings are slowly raising up so I dont think the light and heat is hurting them. lights are about 1 ft away right now. Should I put the light only inches above the babies or keep as is for now? Feedback and some thread buddies much appreciated. I will elaborate more later...

Pics of seedlings, trying to get this computer stuff down...

Dont know if Im gonna get any help b4 I go to bed but am wondering how they will be over night, the lights will be on. Worried about them drying out, I will wet em a bit b4 I turn in. One last question, water Im using is tap water left out for 24 hrs. Do I need to ph it for seedlings, if so what should the ph be for this stage of plant life.

its been a week since I last posted, let me tell you this growing lark is a full time job. Im sure as you get more experienced no time gets wasted and you can do other things with your life other than be in a garage sweating and working any spare momments you have and getting it in the neck from your other half that it is feeling neglected, but other than that I love this shit its fascinating working so closely with mother nature and her blessings.

So yeh I have been going forward adding to the grow room as necesitates. Promise will put pics up tom. Still not much to see of my lovely children yet, to be honest I was and am still worried that they are ok. I am new to this and dont know what to expect, got done with the T5's about 2 days ago, have had them under a 400 MH since, the light was up high to begin now it is 2 ft away. Im wondering if they should be bigger for their age, anyways just ranting would love help and please stop in.
