Hi all. I am setting up my first grow. I am using a dr80. I am trying to fit a Phresh 6 x 16 filter a 6" cool tube and a 6" inline fan. There doesn't seem to be enough space for all that. Is it alright to put the fan on the outside? I am planning to put four plants in the tent also. Any feed back will be great. Thanks.
as long as it still has the power to pull the air through the filter & cool tube, it will be fine. middy
Let me understand. You are pulling air from inside the grow room through the cool tube and exhausting outside of the room, correct?
Yes. It will be filter with duct to cool tube, duct from cool tube to fan which I want to put outside the tent cause I have no more room inside.
My plants have been above soil for one week now. Right now they are getting light from T5's. I want to switch to a MH soon. It will be a 400w MH. I have a dimmable ballast. Will it be better to start at 250w or just go right to 400w. This is how they look after one week, do they look ok? I think they are going good, I'm probably just worried cause this is my first grow. Any help will be greatly appreciated.
And I dont think theyll need 400watt mh for a week or two, once they have established some roots and more vegetation. 250 Im not sure about, but I know that seedlings require fairly little light until they establish themselves, those little leaves cant take in all the energy youd be shooting on em
Just keep em under there untill there about a 1/3 of the way up your space. That way you can flower and be comfortable. Just dont veg them to long that you run out of height to flower with.
IMHO, I believe it is more important to get the other details of your grow down before fooling with CO2. Just providing a lot of fresh air will give your plants CO2.
Easiest way to add co2 to ur plants is seltzer water sodium free in a spray bottle just lightly spray the leaves
I am going to switch to 12/12 today. I have 4 plants going, I have been LST two of them and I'm going to top the other two. I read somewhere that you should too in veg and wait 7-10 days before the switch. I was going to top and switch today, will I be ok doing that?
I know it is a bad pic but I think you can kind of see the problem. I have some yellowing on a couple leaves on one plant out of the four that I have. Can anyone give some insight as to what I can do and if I should be worried about it.
