Hi I saw on a Jorge video that you can use a green bulb in your grow room so you can work during the lights off period as the plants cant see the green light - does anyone know if a simple green coloured bulb from a hardware store is all that is needed? Thanks

Will a dehumidifier help lower the temp then? I have one of those already so thats not a problem to use Thanks

Hi I wonder if anyone can advise me (again!) there's one thing that troubles me about ventilation. If I am to keep my grow room at around 78 degrees and I am intaking air from outside to cool the room, what happens when it's more than 78 degrees outside? Surely if the outside air is warmer...

Right, clean, dry, mould free and pictures I got it :hump: I know many people do it but is it safe posting all your work online, can' you be traced by your ip address or summin?

Yes polyethene is plastic, like thick black plastic damp proof membrane. The floor of the actual grow area will be covered with carpet but the room it will be opened up into when im working in there will have a carpet - I guess then if it's kept clean it'll be fine? Thanks people :mrgreen:

Hi I am going to make a grow room within a room that is not used, the floor of the grow room will be covered with polyethene but I'm wondering is there any need to take the carpet up in the room that the grow room is in? Any advice appreciated

Hahaha :hump:

Thanks for the help, I just wondered if the light on the nute solution was any probs. In the one I'm looking at the tray covers almost all of the res with very little gap either side so that should be ok i guess.

And this causes no problems with the nutrient solution warming then? Thanks

When using a flood and drain table do you need to use a top sheet cut around your plant pots to stop the nutrient solution being directly under the lights during the flood cycle? Thanks for any help

Hi there My set up is ebb and flow growing in rockwool cubes. First off at what point do I stop just spraying the seedlings in the propagator and put them in the ebb and flow table. Then how often should I feed them and for how long should I flood? And does this feeding cycle change as...

Thanks for the help fellas

Got some double dutch, sposed to be the bollocks I'm told, big hit and big yield. I hate working on cars to be honest and as for weed, only time will tell but I got a feeling the rewards will make it all worth while. Yea the seeds are low in cost when you look at what you get out of it but...

Thanks fdd How much light should I be looking at to keep a couple of mothers going? and is pruning time intensive or just a once a week thing?

Sorry to bump :? but Would a mother be better off in a room on her own under a couple of fluros to keep growth slower? I kinda need to decide as I'll be building real soon. And am I right in assuming I'll have to keep pruning mam to keep her to a realistic size? Thanks

OK thanks Can I just confirm that I soak the rockwool plug put the seed root down and I just keep it in the propagator, keeping it moist by spraying with just water until the roots come through, at which time I plug the block and get it into my ebb and flow unit? Just want to make sure is...

When do I take a rockwool plug containing a seedling or a clone out of the propagator and push the plug into a rockwool cube and get her vegging? Would it be when the roots come out of the side of the rockwool plug? Thanks

Hi, I want to keep a couple of mother plants and start using clones to grow from I just wondered how I keep the mother long term. I understand she will be kept in a constant state of veg so do I need to constantly prune her to keep her small and stop her getting too big? Would I keep my mother...

Cheers guys I bought a primair after, keeps the fan turning as much as you set and kicks into full power when the room gets too hot - switch it on, forget about it, nice

Hi How does everybody control their temperature in the grow room - I assume its by using a combination of fans and heaters but how do you control them? Do you just turn them up and down as you check your thermometer or do you have something more complex? Please I really need to know a poor...
