what size net pots for hydroponics

Which size net pot to use?

Does anyone have an opinion on the best size net pot to use with hydroton?

Is it better to have more or less hydroton/medium for the roots to be in before they get to the air and water? Will the size of the net pot determine the size of the plant in any way? Or is the size of the net pot determined by how large you will be growing the plant (like just providing more support for larger plants).

I’m making a bubbleponics system with an 18 gallon tote (probably 12 – 14 gallons of water+nutrients), putting 6 plants in it. Is there any advantage to using 5″ pots instead of 3.75″ pots?

popojojo:
Cool, that makes sense.

faller:
I wondered about the possibility of doing more, smaller plants, sort of like a SOG? You’re gonna laugh, but my bloom light right now is a GlowPanel 45 LED light (yeah, 28W total ) and a couple 23W CFL bulbs. I’ve got a 4 bulb 2′ T5 fixture with blue bulbs, proly gonna get red bulbs for it and use it too. I actually got a yield of just under 1 oz (dried, Maui Waui ) on my first grow using only the 28W LED light and 1 23W CFL, in a 5 gallon bubbler bucket with 10″ net pot and hydroton (but it took 7 months). I’m looking at adding a 100-200W LED panel in the near future. I’m following those threads to see the best one to get

Great idea – I’ll fill the tote with water to sit for a few days under my lights and see if it stays cool – it’ll be on my basement floor, and I’m currently using LED and CFL lighting so I think the temps might be OK w/o the cooler. Last winter when I started my first grow, I insulated the floor of my tent cause I thought it was too cool, LOL. IIRC, air temp got down to 65F at night with lights off. I never thought to check the temp of the water in my bucket, just air temp, thought the plant would grow faster if it was warmer (now I know the small amount of light I was giving her was a big part of her problem). I wish I had come here and read everything I could find before starting, cause I made a TON of mistakes. I’m not complaining cause I got almost 1 oz from my Maui Waui girl, even with all the mistakes I made. But it’s amazing how much good info is here and I’m looking forward to a much better 2nd grow! And hopefully this time it won’t take 7 months.

Net Pot size for Tomato/Peppers

I am going putting together an Aero/NFT system.

The net pots will go into a 5×5 vinyl post. I plan on using net pots with neoprene to hold the plants.

Do you recommend 3″ or 3.75″? The smaller ones will make it easier next year to start plants in. The larger should help with bracing and growth.

Thanks for any feedback

I almost exclusively use 2″ net pots to grow both tomatoes and peppers in. The roots grow out of the pots so net size won’t really affect its ‘holding’ ability. besides tomatoes are so huge you’ll have to stake them anyhow.
Be sure you secure the vinyl posts as it will roll over if the plants decide to lean to the left or right too far.

Good point on the securing of the vinyl posts to prevent rolling.

I do not have an NFT yet, but I use 3″ baskets for my Toms and Peppers in a DWC setup. As mentioned above, staking is needed.

So it sounds like 2″ will be fine. The cost is half, plus it will be easier to do starters with them.

I will definitely take your advise and strap the post down.

I was going to do 4 per 8″ post. But looking at Grizzman’s set up, he was much closer together with his peppers.

Thanks for the help,
Chuck

Hey Chuck, check this article out. It has in depth step by step plans to build a setup like you describe. BTW, this magazine is incredible! This is off topic, but they also have a article about plasma lights. Pretty interesting stuff!

My peppers were set at 8″ on center.

another goofy question from the peanut gallery. when you say ‘peppers’ I assume you mean bell pepper varieties AND like spicy peppers too? Am I correct in my assumptions? They are similar enough to group them all together? I ask because I have German Green tomatoes and Cajun tabasco seeds I was going to plant together. would that be ok? Or should I go with one of my bell pepper plants instead?

I don’t know about others, but I do not lump them all together.
With “peppers” and tomatoes, you have got at least 10.000 varieties of each.

Growing tomatoes and bell peppers in one setup and with one nutrient isn’t the worst you can grow together, though. Bell- and hot peppers (generally speaking) are not unlike tomatoes, best grown with high Potassium and relatively low Nitrogen formulas. Well, tall bell pepper plants are often growing fast and can use more Nitrogen than their smaller relatives. And, most hot peppers (c. chinense, c. baccatum, frutescens and pubescens are much happier with lower nutrient concentration but don’t mind somewhat more Nitrogen (in respect of lower concentration) as tomatoes. PH is compatible anyways, all in all – no big deal to grow them together, as long as you follow these rules that aren’t a big secret anyway. 😉

Btw: your Cajun Tabascos should be capsicum frutescens, and in case, they grow slowly and build up quite a structure before going to blooming and fruiting stage (what you aim for in fact) – and hence they will take several month to mature and grow best with low nutrien concentration and high potassium content (as seen earlier). The good thing about them is that they are quite robust and forgiving, if treated decently.
Btw: Capsicum frutescens is what grows best here in Thailand and in this “rough” climate.
