Looking for some advice for first time solo organic grow please

Hello have been browsing the site cant seem to find an actual search option other then scrolling through pages of threads. I am a first time solo gardener. I have seeds on the way and need to be ready within the next couple of weeks. A few things im wondering about are...

Lighting inside my tent, I was thinking of using 400w MH for vegging and 400w HPS for flowering time. My tent is 4x4 by about 6 ft tall. Will 400w be too much heat? I dont think so but im wondering. Also is there a certain brand of bulb that is better then others? Not on a super tight budget but not looking to go broke either.

Soil..? I am wanting to go organic, looking for a pest free sterile medium are there any brands I should use or avoid?

Cfls? I have read they can be good run down the sides for extra lumens is it worth the effort?

I will be growing in 3 gallon pots to start dont plan to let plants get too tall before putting into flower.

Thank you for all your help info advice in advance.

A 400w for a 4'x4' tent is great. Heat will depend on your setup and venting situation but assuming you are running with a decent setup (inline fan, air-cooled hood, etc) it should be easily controllable with a 400w in that space. I've only used Eye Hortilux bulbs, so I don't have much of a basis for an opinion on other brands.

There's no real reason not to use any CFLs you have and if you want to. I usually take out the CFLs after the plants get bigger just because I can't be bothered with constantly adjusting them to keep them close - personal preference though.

For organic soil, I would say Roots Organic "Original Potting soil", and their organic nutrients arent bad either...as for the cfl's, the more light the better, but its completely up to you. Also, I recommend the 3gallon "Air Pots"..they are great for your roots because they don't cause the roots to go in circles. They air prune your roots, allowing you to have a better root system.

Thank you both for the reply I appreciate it. I did mean to come off sounding dumb, I no longer have the ability to call or go over to the caregiver who was teaching me everything as his illness finally won and hes past on.

Also he had issues with bugs and mites I believe it was the soil who knows? I did not like the Fox farms soil he used or the nutes he was using for my own personal garden I love mother nature and want to stay as clean healthy and chemical free as possible. I look forward to starting a journal about my first real garden experience. Thanks again for the replies.

I would recommend using larger pots. You never know....

400 sounds good just make sure you got some fans i try to go as organic as possible i use iguana juice from Advanced cfls are all i use to grow
