    You guys really helped me out with finding a FT with the IBC idea..

    so now i need your help for some grow bed idea's.. ???

    i dont want to cut up the IBC for a grow bed, and i thought of the idea of cutting rain barrels in half but its too much work on the siphon side of things..

    any idea's??

    I am in the same process as you , trying to get my setup together . Maybe a master siphon that drains your beds at the same time?

    I too am looking for beds , rather not use blue barrels unless i have to. Home depot has large totes that can be used they are the perfect depth , but again the siphon issue and expense at like 20 bucks a pop also they are not very wide or long...

    I think old bathtubs are the way to go

    3 bathtubs as growbeds
    1 bathtub as sump
    one megasyphon

    the perfect unit.

    cheers Lou

    dont do heaps of blue barrels. I almost had to sell my heart and lungs to pay for the plumbing and decided to halt the extension till I also work out another way (30 x 1/2 barrels that is)

    Bathtubs or make GB me thinks

    Uniseals make the plumbing a little cheaper.

    Just a thought.
    Cut the ends out of the half barrels and join them together
    either heat gun or stainless nuts/bolts with silicon.
    If you join 10 together you'll have 3 long growbeds.
    Seems such a shame after all the work you've done to let
    it go.

    cheers Lou

    thanks for the responses guys.. i've been doing alot of thinking on this.. found a guy that sells IBC's for $100.. i might just fold and buy 3 of them, 1 for the FT, one i'll cut horizontally, use the bottom as the sump and the top as a grow bed.. the 3rd i'll cut each side vertically and get 2 larger GBs.. what you think?

    Hi All,

    Have come to conclusion the cheapest (and probably best) way to connect blue barrels is with "TopHat Grommets" you can get both 19 and 25 mm. I would go for the 25 mm personnally. Cost of a grommet is less than $1.00 each, then use a straight pvc hose connector.

    Grommet into base of barrel then push in connector. Grommet into 90 mm pvc pipe and push onto other end of connector.........job done. Connect all barrells together the same way and at the end fit a Mega Syphon using all 90 mm fittings.

    Can get the TopHats off ebay or here is a link I found......

    Couple of photos.........although like others I did mine the expensive way.

    have used the top hats and they are bastards to put the pipe through and then they leak. Would never use them again.

    As per our discussions, I would agree that's the cheapest way. To do a bank of 10, it would cost approx $60 for the outlets and Siphon (not inlet)

    nick - I have 5 bb with 19mm grommets of inlet and outlet, no worries here. You need to drill a hole 3mm wider, im sure you know that. Less or more, you wont get it in or it will leak :)

    Yep, 3mm about right. They recommend and I bought a 22 mm holesaw for 19 mm grommet. Use a bit of silicone lube or vasoline when assembling (don't use oil). I had no problems with them leaking, you probably made the holes too large.

    I question Chainsaw, you dont have any issues with it breaking the MS early if it has a minor leak?

    ahhh :)

    With the top hat grommets, occasionally they could leak a little bit. As its on the siphon side, if it sucks a bit of air in, could it break the siphon to early? I think not, however you run them :)

    Nick, Tophat Grommets are not designed to push a pipe through............for that you use a "Uniseal". TopHats are designed to be able tap into a larger pipe (normally PVC) and run a low pressure hose from it, normally with LP irrigation poly pipe,and using the poly fittings.

    You wont have problems with sucking air or affecting the syphon..............

    One test is worth 100 expert opinions.
