"LAPOND Hydroponic Grow Kit - 3 Layers, 108 Plant Sites, Pump Timer"

Description

This hydroponic outdoor grow system is designed for fast, maximum-convenience vegetable gardening. Perfect for beginners! No experience needed. More nutritious and better-tasting than soil-gardened produce because oxygenated water and nutrients are delivered directly to the roots.

Adopted food-grade PVC-U pipes, each PVC pipe diameter is 2.48”/63mm, hole size is 1.2”*1.2”/30mm*30mm with ample space for vegetables, flowers, and plants. Suitable for lettuce, spinach, pakchoi, cabbage, radishes, strawberry, herbs, rape, beets, garlic seedlings, canola, celery, etc.

The water pump with timer allows you to set the on time at 5/15/30 minutes intervals and off time at 30/60/120 minutes intervals to reach the nutrient film technique. The circulation mode can also be set manually or automatically according to demand, making the pump more durable, saving nutrient solution, and making the vegetables grow better!

Extremely simple to assemble and use, only need nutrient solution (not included), no odor, very clean. It is easy to take care of, no arable land, clear weeds, save time and effort.

Being close to nature, you can purify the air and make full use of space to keep the crops out of the soil. Especially suitable for leafy vegetables in homes, gardens, and offices. LAPOND provides a 1-year warranty on the Hydroponic Grow Kit and accessories. Please contact us if you want to add extra pieces.

Will 1 inch rockwool cubes fit in net cups? Yes, I threw away the garbage ones they provided and replaced them with 1-inch rockwool and it fits perfectly.

Can I grow marijuana in this system? There is not enough room for the roots. Try a system that uses a 5-gallon bucket like Atwater Hydroponics. They also have good support, but I only grew tomatoes with that system.

After the fill cycle, the water does not fully drain out. My understanding is the water has to fully drain out or the roots will rot. Roots rot when there is insufficient oxygen for long durations of time while being submerged completely. As long as the 5min on/30min off cycle continues, there will be plenty of oxygenated water around for roots to be healthy. Even if it does not drain entirely. Google search 'Deep Water Culture' hydroponics, and you will see that roots can remain totally submerged in water for the entire life cycle of the plant as long as it has a decent bubbler to introduce oxygen. My quick advice is to pull up a plant once a week and inspect the root system. If you see bright to off colored white roots (or perhaps even tan colored due to using organic nutrients), then you know things are healthy! If you pull up a plant and its root system is brown with a somewhat tacky/slimy appearance, then you know you need to run the water longer for more oxygen (try 15min/15min), nutrient solution is too strong, or pH is out of balance.

Is there a growing medium better than the sponge that isn't so hospitable to algae? All you need to do in order to avoid algae on any medium is to cover it completely. You can make a circular cutout that will prevent light from reaching the sponge, that will go around the plant's stem. By blocking light from reaching the sponge, you will prevent algae from growing in the first place, and the plant won't have to fight the algae for nutrients and will grow faster and stronger as a result.
