My NFT hydro system
Hi Stella!
I have been a fan of your site for a long time now; It helped me hydro gardening in my new so much in getting me set up (finally!) Start greenhouse! I am a total newbie, gardening, but have a small hydro Veggie/cabbage patch in the free enjoyed for many years. I built their own hydration systems, armed with photos and instructions found online from various sources mean. I have taken your advice about how to use the flora series of nutrients.
In most cases, I think, I enjoy beginners luck. However I had with a Royal battle turned spider borders (not diagnosed, until the damage was too severe to save the plants) and a disaster with a timer on the pumps failed. Live and learn, as they say.
I search info, why my plants, while end apparently never go up strong and healthy, are currently only workshop and workshop without flowers/fruit growing. I read about "Increase" the tomato plants, and plan, try. I have in the attached photo, which is from my NFT system, tomatoes, cucumbers, peppers, peas, beans, squash, lettuce and strawberries. The only things that are produced are the cucumber plants. The rest are well displayed and strong, but you don't have either or a few flowers, blooming fruit set. The lettuce is limp and irregular.
I know this is vague information, and that there is a lot of things, which perhaps could be the problem. The greenhouse of fans that hot air exhaust is barrelled, and there are ceiling fans, gentle breeze over the plants in circulation. I fog the plants twice daily, and refilling or replacing the reservoir solution is needed. I use the recipe for "Transition stage flower to fruiting". The light is natural daylight. I am in Maryland, and as all the others have experienced a very hot summer of this year. Many days it is well over 100 in the GH and not a lot cooler at night. I suspect this is the primary problem (too hot), but I'm also concerned about whether I'm doing something wrong with the nutrients or some other facet that I can control - how should I put in additional lighting closer to the smaller operated (salad)?

Any advice or tips would be very much appreciated! Thank you for all you do for any more help!

Hello Jeni,.
Gosh, which have an impressive system to push together! Hope we can help.
Definitely, I suspect the record that the high heat wave for your crops not fruiting is responsible. The optimum temp for hydroponics is between 70-80 degrees. 100 + is definitely too hot. You need to get it barrelled out there, perhaps with more powerful exhaust fans. Some other random ideas:
Sure, use 1 make the "flowering" stage of nutrients, not growth or transition.
2 Try, some insulation wrap-around the nutrient to try vats, the temp of the solution down. Write an aquarium thermometer in it and bind to the pump, so that it can be retrieved easily. Hot Nutes will kill or keep the plants. If you have the means, you should also to chiller for VAT; but these are expensive.
Set 3 note some shade cloth over the top of the greenhouse, at least during the hottest part of the day. You should get much sunlight from the side walls. And think of a way to increase the air Circulationa and waste gas, heat better built.
4 If you steamed up the plants while sunlight shines down hot on them, this can actually damage "Steam" and it.
Well, there are some ideas, you are in the right direction. Hope that inviting to join other hydro fans with other helpful ideas!
Good luck to you and hope this helps!
