no moving parts uses an air pump for the motive and to generate suction to pump the liquid this also dissolves air into the water i did also think you could add them between the pots to generate a greater current ... also can be used to mix nutrients into the system the...

jet pump design coming on reduced its size so inlet and outlet is 36mm pipe and will try 3 connected together which should increase the pressure and push the water faster

based on the Current Culture H2O - Hydroponic Cultivation Solutions type system basically configured like they have it 2 tank connectors on each bucket and then connected to each other ...you can connect in a circle and use the reducing tee to connect to your water pump and filter that...

Decided to attempt a 3d Printed undercurrent Hydroponics system (UC RDWC) , as they are very good systems but just cost a stupid amount of money. It seems that things like the large tank connectors realy drive to cost up. i also seem to have collected a lot of filament that i can...

Wheelie bin / barrel-ponics hydroponics looked up the concept the other day just get a barrel fill with water, mix up your nuits in it . The plant your plant of choice in the top in net pots and never water or feed again for the whole seasion. i used masterblend 4-18 -38 with...

looked into Master blend but its pretty pricey so worked out a pretty identical mix using a good fertilizer as master blend is £60+ for just 4 kg using what i found is like £60 for 50+ kg YaraTera KRISTALON BROWN (3-11-38 + Mg, S, B, Cu, Fe, Mn, Mo and Zn) AS BASE = 10gram...

it does but you have to quiz them on what actualy is used in the lights , it is tempting as if they are using the same leds and drivers as are used in original products for like £500 each you could buy 3 for the price of one original Florence even if there is a slight difference in...

just looked on chilledgrowlights and the have only a few things for sale on their site have thay hit the wall or something ??

i seem to always lean towards driver output figures on what it can deliver to the boards or cobs , its just weard that the 2 kits i used as examples seem to be using 2 different conventions 1 input watts and the other output thats all . it makes it seem more powerful than it is ?? some how

but then why is the 320W XL QB V2 R SPEC LED KIT based on the output watts of the HLG-320H-C1050A output power 320w surley you do one way or the other and base your watts of the kit on input watts or output watts, not both ?? ie this light kit should be something like a 353.28w with...
