Heating Pads

[Tommygirl]

Ok, who here thinks it's a good idea to use a heating pad to warm your res a couple degrees?

[Cyclonite]

why do you want to warm it? Well your target temp should be 60-70 F

[Tommygirl]

My res temp regularly stays as low as 64, and sometimes goes lower than that. I'm concerned that it's too low and is stunting the growth of my buds. I just want to bring it up 2-4 degrees without having to put out $30 to do it.

If it doesnt go below 60 for an extended period of time dont worry about it. Insulate your rez...

[Tommygirl]

I have it sitting on a folded up blanket to keep it from making direct contact with the floor because when it did the temp dropped to the high 50s. Sadly, I can't keep the room above 68 - 70. I'm sure that's part of the problem. Think a comforter would do the trick?

[Cyclonite]

Not sure what container you have but buy some actual insulation for houses and suck with a high rating. You could wrap them in a loose garbage bag and pump it full of spray insulation or instead of a bag use a larger container and fill in the gaps with insulation. A blanket is better than nothing. Thats a good temp for the room to be....are you using HID lights? they can warm it up and boost your harvest big time....its well worth it.

My res is just an 8 gallon Rubbermaid type thing with holes cut in the lid to fit the net pots.

No HID, though I'd love to have a nice 250W'er HPS. I just can't afford it right now. I'm using CFLs at the moment. I have 126w total and 84 of those watts are 2700K while 42w are 6400K. I'm considering replacing my three 42w bulbs with 3 100 - 124w ones. If I can find some that I can afford. Replace at least one of them anyway.

I'm also gathering what I need to build an E&B system.

my res stays at 70-72, the lady at the hydro store told me thats ideal, however ramo from urbangrower.com suggest 52f is ideal for mj, now ive never tried this and dont know how true it is, but i do know advanced nutrients spend close to 1 million a year in research and development on growing marijuana, so it may be true

[Tommygirl]

Wow...52F? Unreal. Maybe I ought to set the res back onto the bare floor.

[caliorbust]

52F is supposed to be the temperature at which water can reach peak oxygenation, but i definatley would advise against any heating of your res

[Cyclonite]

thats too cold go for 65-68

Hi tommygirl
I'am a carpenter and build high dollare homes.if you are trying too keep the temps in the res at one temp I would insulate the bottom of my tub with two pices of foam board.they are 3/4" thick and come in 4'x8' sheets.They have a silver foil on both sides.very easy to cut.You can cut the board and make a box that fits the res,glue it together with a tube of silcone and a couple of nails.than set your res down in it.Or you can get one or two cans of foam insulation in a can.WEAR RUBBER GLOVES when you spray this stuff or you will wear it off your hands.Turn the res upside down and spary the foam on the tub.Bottom abd sides.The foam will expand two or three times it size.Let it cure and you can shape it any way you like.It is so lite in weight you will only add two or three lbs. to the tub.After it's cure shaped and ready you can paint it with a water base paint,water base only.
Hope this helps and not to confuseing. The foam board and spary foam you can pick up at most home building stores,hardware store{homedepot & lowes} .

All the options for answers above are so cool I can't even pick just one!

Cold water will hold more oxygen then warm water will. 68f is just about perfect for this plant.

If you go below that you can use submergible water aquarium heaters from wally world for less then 15 bucks.
