What are the best drip emmiters for gravity system?

Flowki · Jul 24, 2021

Im hoping to use 15L res tubs per plant, with individual line to each plant. The small reses will only be elevated around 1.5 to 2 foot off the ground, the base of the reses will be above top pot height, basically. There are a few reasons why the setup is intended this way, I'll save you the details unless they matter. The real questions I am asking is what drip emitters will be the best (if any) under this low pressure situation. I am hoping that a 24/7 gravity system is doable, I don't want to use a large single res and pump/s. I'd be looking to refil the small reses every third day, if the gravity pressure or emitters allow it?.

With vpd somewhat in line, I think the plants will avg 4L each per day. On the ''last'' day their should still be around 3 to 4 L in the reses, acting as a pressure buffer. Would that be enough?.

I can't see why it wouldn't work, you can buy drippers with a 5mm nipple and a little tap to adjust the drip rate.
If you need more pressure raise the reservoir some.

What are the odds of such small drippers blocking with calcium, I'm hoping since it will be continues flow then the salts will not solidify within the drip head or exit hole?. The height is locked due to room dimensions.

Do you or anybody else have opinions on reliable drip emitters at this flow rate?. I could buy some from a basic garden store but I'd tend to favour a specialized company in terms of product quality, so long as they are not extortionate.

I have never had any problems with them blocking or anything building up but I've soft water idk if it's possible with hard water.

I've got a automated system that I put together for around £30, it's basically a pump (£15) and some 5mm tubing with a manifold and some Ts Xs and taps to spread and control the flow rate.
Being 5mm right through the chances of blocking are slim, the reservoir has a filter and so does the pump in feed bucket.

Where did you purchase the emitters?.

Have you looked into blumats?

I've used blumats but with split reses at that height, the results were hit and miss, potentially due to pressure rate. A large single res or pumps are not my thing. Some strains don't like the same amount of N as others, since no run off in blumats N was building to much for my liking. If I reduced N to stop that, the strains that liked more N or getting a little more light intensity suffered. I don't want to be locked into one strain, so drippers will hopefully give the ability to use individual run off where needed. That at-least removes the need to use dual large slave reservoirs with varying nutrient rates, too much hassle.
