we call this a "coliseum" setting. I've seen this before. Automation and hydro does not solve the problem. The temperature of the crown should be 25, the temperature of the root should be 18 celsius. The root is located at the level of the lamp. The photo shows that the plants are hot. The leaves are crumpled. Here it is necessary to regulate the temperature of the solution in the pipes.
It is necessary to install additional automatic cooling of the reservoir with the solution, and this is not so simple, especially for the beginner. Yes, I see the work of a professional. I know that the most effective method of cultivation is clones and hydroponics. I planned to make in the installation racks under the clones to show the maximum result. But, unfortunately, I had to postpone this experiment, because I realized that it is very labor-consuming to fill all space with clones, so that there would be no gaps! It is necessary to grow them, then cut them off, then sprout .. very troublesome, and it takes an unrealistic lot of time for me, and what if it's a newbie !! This is a job of a pro, my friend!
As for hydroponics, I do not know how you are, but we do not appreciate it at all with gourmets! I tried to grow hydroponics. I did not like the taste or trip! The taste is artificial somehow, as in McDonald's meat))), first kills, and after 15 minutes you are sober))). This is not marijuana, it's surrogate! IMHO
For this reason, I refused hydroponics!
Hydroponics gives 30-50% more than the soil. Clones give 30-50% more than the classical cultivation. I got on 1000 watts, on the ground and four bushes 2.5 kg dry buds. Really, having slightly modernized the installation, I will get 3,5-4 kg. with a square meter and 1000 watts,- I'm telling you exactly. If I had not killed one plant now, it would have been 3 kg.))
Conclusion: most likely your friend uses the wrong bulbs, advise him Fmlmps Green power - this is the best sodic in the world. Phillips on lighting greenhouses occupies a leading position in the world !!
PS: as we say, the hands of this guy are golden, if he is not too proud, let him write to me, I will tell you how, under the same conditions, he will be able to remove not 1, 5, but 3 kg of dry buds!
