All of this is coming from a noob grower, on my third right now, but imo:

1) Go with the larger tent if you can. More room is ALWAYS better when feasable.

2)I don't see the carbon filter being a problem, however, even if it isn't optimal, you will have plenty of time to replace it IF you start noticing smell.

3)Idk. Sorry. I just got my first samples of FF nutes about a week ago. If you email them, they will send you free samples that would be enough to run at LEAST one grow of 4 plants, and maybe 2.

Hope it helps!
budlover13 Reviewed by budlover13 on . A few simple questions Hi folks, So I'm going to order a grow tent. The two sizes are 40x40x78 and 56x56x78. I only need about 4 plants and plan to grow them to about 4.5-5ft tall. Will 40x40 be a sufficient area for four plants or should I really opt for the 56x56? I don't plan to do anything fancy like SOG. Will just be plants next to each other. The second question is about carbon scrubbers. I bought one 2-3 years ago. It's only been used once for about 1 months, and was only on when the fan was on Rating: 5
