    Ventilation Advice

    How do I constructively say "no". You can't make a square peg fit in a round hole mate. It looks to me like you are trying to run before you can walk...... (wow cliche after cliche) or you would know this already. Growing is not the piece of piss that many new growers think. A few pots, bit...

    vert grow question?

    I am on my first vertical (sog), using cool tube for a couple of reasons but what I really like is no part of any plant is more than 8-9" away from the bulb. Looking very promising at the moment, 3 weeks to go. 10-15% light loss doesn't neccessarily mean 10-15% loss of yield.

    Air Intake flower room--please help

    Heat discipation / concealment is not an issue for you being legal. But here in blighty..... vent and recycle simply means to vent into you house and create air movement through out the house and loft. My extractor for ligths are on a closed system and draws cool air in from the bedroom below...

    Looking for opinions/tips on setup!

    720 cfm fan with controller will take care of all your needs and some in reserve. Overkill can always be toned down and it's never a bad thing to have exra ammo in your arsenal.

    Air Intake flower room--please help

    OP... be carfeull of venting up ya chimney. Having a fire burning will produce a very different heat signature to IR camera than having 700+ cfms of warm air blasting out at pressure. As much as possible try to vent and recycle inside, better co2 and less suspicion. Especially during late flower...

    gorilla grow tent trouble

    LOL. You probably used the horizontal poles for the uprights. I did the same thing. My uprights were a different length to horizontals but all the connectors are the same.

    First official grow room (with pics!) Help with possible problems.

    I wouldn't worry about that, 2 weeks rooting clones, 3 weeks veg. Use ya cfl's if growing to fast. I find the timing is perfect, if anything ya might need a few extra days vegging.

    First official grow room (with pics!) Help with possible problems.

    Lovein the toilet connector on ya filter. Good job. I made the same mistake of buying a cheap tent. See them poles holding your filter up..... I guarantee the plastic ends will snap when you introduce some heat, it might take a week or 2 but it will snap. Ya need to re-enforce with tape or...

    Heavy 16 problems in ebb and gro

    I set my flood levels to 1/3 of the pot height. roots are never fully submerged and therefore won't drown. Each flood and drain sucks oxygen across the rootball so no rot. So long as you don't submerge your roots completly you can flood and drain continually, think NFT. I would advise against...

    600w hps air cooled ventilation questions

    There is no such thing as overkill in this game. You can always use a fan controller if ya fan pulls too much. Better to have that increased power available to use than not have it. So many times I have psoted about my shed full of under powered, low-medium quality equipment that just doesn't...

    Heavy 16 problems in ebb and gro

    DIY Ebb & Flow - I'm learning!

    I tried and failed with the drippers. Salts are your enemy with drippers, easily clogged and as with ventillation, your water/feed will always find the easiest route. when your drippers / nozzles get a slight blockage, the flow stops on that drippper and pushes through an easier route. You may...

    1 fan with 3 filters vs 3 fans + 3 filters for three tents?

    You cannot apply a formula to the resistance your ducting will create.

    1 fan with 3 filters vs 3 fans + 3 filters for three tents?

    You put your 2 flower room lights on opposite each other and your veg tent, I am assuming will be using CFL's. So no you won't be increasing the heat like you describe, you will be disipating heat around all 3 tents. Also during the winter months you will be heating the other rooms when lights...

    1 fan with 3 filters vs 3 fans + 3 filters for three tents?

    It is doable from a air scrubbing perspective but not sure how it will fair for cooling. Connect you fan directly to your filter and put it in you big tent high up. You then need to connect each of you tents together with ducting. So connect big flower tent to small flower tent then connect...

    DIY Ebb & Flow - I'm learning!

    There is a natural progression with growing. My ultimate goal and most probably share, is to have totally nil medium. Nothing to wash, nothing to try to get rid of every grow, nothing to buy in aand ultimatley nothing to raise suspicion. I think you will still have root damage with you hydroton...
